f5=V^ SATYRIDAE ^T^ G Weymer 173 Family: Satyridae This family, which By very rich both in genera and sjiecies, is well distinguished by several characters not only in the perfect insect but also as larva and pupa, so that Satyrids are easy to recognise in is all stages One of the chief characteristics of the butterflies consists in the basally swollen veins of the fore- In most cases it is only the costal vein which shows this bladder-like thickening, in many cases the median likewise has it, but in some genera also the submedian, e g in Oressinoma, Coeno7iympha, and to a less extent in Pierella The first three genera Callitaera, Haetera and Pierella have the submedian of the forewing, apart from the above-mentioned bladder-like thickening, also basally forked and form in this the transition to the Ithomias, which is also indicated by the partly thin, hair-like scaling and the transparency of the wings Of the subcostal veins mostly arise before and the rest behind the end of the cell of the forewing, but several genera differ in that the subcostal vein only arises at the end of the cell or behind it The middle cell of both wings in all the Satyrids is closed, the lower discocellular vein of the hind-^-ing moreover in almost all the genera runs into the curve of the upper median; only in two of the first genera, in Haetera and Pierella, is this not the case In Haetera the lower discocellular and the median meet at the origin of the middle median vein, in the genus Pierella on the other hand between the origin of the middle and that of the lower median wing The shape fore^^'ing, of the wings is Sometimes both wings are rounded, sometimes only the undulate or dentate Often the forewing also shows angles rather variable whilst the margin of the hindwing is at one of the racUals, sometimes the apex of this wing is sickle-shaped or the costal margin itself is produced into a sharp point Moreover sharper angles and points occur at the three median veins and at the submedian of the hindwing or the lower median vein is prolonged into a rather long tail {Corades and Bia) The inner margin of the forewing in the greater number of species is straight or deviates but little from the rectilinear, only in the (J(^ of the genus Antirrhaea and in one species of Caerois is it so much outciu'ved that the anterior part of the hindwing is covered by it In this expansion is placed on the under surface between median and submedian the so-called scent-organ, consisting of a row of closely approximated, stiff hairs, which often form a semicircle or a wedge-shaped, pointed ellipse, the curlj^ tips of the hairs bending over towards one another In addition to the genus Antirrhaea the scent-organ is only found in the ^^ of the Caerois-species In one species of this latter genus, however, it is placed close to the inner angle on the underside of the forewing, so that it is not covered by the hindwing Tufts of hair are also found in the genus Bia on the upperside of the hindwing, smaller hair-pencils in some Euptychia Perhaps these may likewise be regarded as scent-organs, as they only occur in the ^^ The greater proportion of the species of Satyrids are above uniform dark brown, so that the markings are confined to the under surface Here belong most species of the genera Taygetis, Euptychia, Lymanopoda, Pedaliodes and Pronophila But all these genera show at the same time a number of species which are brightly coloured also on the upper surface and have striking and beautiful markings On the underside the ocellated markings are represented in a variety of ways Several species have also beneath larger or smaller silver spots or silver stripes and dots Some Chilian species have the wings entirely silver-coloured above The antennae of the Satyrids are mostly thin and delicate, at the same time rather short, not reaching half the length of the forewing The shaft widens very gradually into the little-thickened club, only a few genera have a short, broad club The palpi are usually densely and strongly haired, sometimes the eyes are also hairy, the forelegs in both sexes aborted The eggs of the American Satyrids, as far The larvae several species is known, have a rather spherical by raised transverse ridges as they are spherical form, with the sides ribbed or regularly divided are spindle-shaped, thicker in the middle, or hemi- narrowed towards each end, but the head in thicker than the anterior segments, also sometimes with short, obtuse horns above, in The body terminates at the posterior end in points, which are mostlj^ straight, but sometimes also curved upwards The colour is mostly green, but there occur also longitudinal stripes of various colours They live on grasses, reeds, species of bamboo, sugar-cane and palms, remain bidden by day and come out at dusk to feed others also at the sides provided with conical protuberances on which are placed short bristly hairs smooth or finely granulated, spineless The pupae are comparatively short and thick, without strikingly projecting angles attached at the tail-end or lie free on the earth or are hidden under stones They are either Many of the tropical Satyrids are dusk-butterflies, i e they remain at rest all day and fly about near the ground in the early morning and the dusk of evening with unsteady, sometimes jumpy flight in woods or thickets Here belong the dark-coloured species of Taygetis and Euptychia All day long we find single Taygetis in the dense timber-forests, resting with closed wings on the ground, where they can CALLITAERA 174 By G Weymer Herr scarcely be distinguished from the dried fohage and are not noticed until they fly up has been kind enough to give me these notes on the habits of the Satyrids, for which I who Haensch, am much indebted to him, has observed that specimens when pursued lay down flat on the dry leaves on the ground and could then only be found by startling them up The transparent species of Callitaera and Haetera, as well as the nearly allied Pierella, are always found in the shady timber-forests, mostly singly near the ground, and prefer the narrow foot-paths When one comes near them, they rise at a distance of a few paces and fly along the path close to the ground, soon settling again, but only again to fly In this way the weak-flighted insects may often be followed for quite a distance, off on being pursued The least shy of light are the genera Oxeoschistus, until, leaving the path, they are lost in the wood These are freLasiophila, PedaUodes and Corades, thus in general the most brightly coloured forms quently mountain species, occurring at elevations of over 2000 m They are met with gregariously fluttering backwards and forwards on the road or feeding on the ground at the excrement of cattle and other The species of Corades substances, but always near to thickets, where thej^ take refuge in danger not easy to recognize in a bush, as they rest on twigs

in Colombia, Ecuador, Peru and Bolivia even at elevations of over 4000 m single representatives of the genera PedaUodes, Lymanofoda, Pseudomaniola and Cosmosatyrus Among these inhabitants of the

bears white dots before the apex of this mng The under surface is grey-brown, darker in the marginal area, with fairly straight brown lines on both wings, or white dots instead of the eye-spots on the binding and some similar dots at the apex of the forewing A black dot at the base of the forewing and or at that of the hindwing From Pintuc in Ecuador (800 1000 m.), Chanchamayo in Peru, and Bolivia the under surface the ground-colour of both wings straight brown lines — — — — c) With three almost straight, upperside a blue spot on each wing varj'ing in size, —4 mm dark lines only on the underside of the hindwing On the Ground-colour dark black-blue The blue spot of the forewing is elongate, broad and 12 mm long, and is placed on the discocellular That of the P hortona Heiv (43 b) horiona parallel — ANTIEEHAEA By liindw"ing is much lai-ger, At the inner margin — nearly round, 10 of the — 13 mm hindwing there G Weymeb in diameter, 179 and extends nearly to the costal margin in the (^^ a patch of light ochre-yellow, appressed scales surface yellowish grey, on the forewing with brown lines, contiguous in is 10 12 mm in length Under the middle and diverging anteriorl}- and posteriorly, and with a short oblique line in the cell, and black On the hindwing there are black dots basally to the almost straight parallel transverse dots near it hortensia Fldr is a horiensia lines and before the distal margin a row of similar dots Amazons and Ecuador local form which is distinguished by narrower wings, smaller blue spots on the forewing and less rounded spots on the hindwing, M-hich are placed further from the distal margin From the Eio Negro — Geuus: Antirrliaea Hhi — Medium-sized and large butterflies of 65 105 mm in expanse, mostly dark-coloured, only a few having blue, white or red-yellow markings The palpi are densely covered with stiff hairs, the antennae thin, thickened towards the end, mthout distinct club In most species the veins of the forewing are not swollen, only in archaea the costal vein is somewhat thickened and in hela distinctly swollen In the hindwing the costal vein does not arise direct from the base, as in the preceding genera, but on a common short stalk with the subcostal The precostal also arises at the point of separation of these veins This is likewise the case in all the following genera of Satyrids The principal distinguishing character of Aniirrhaea consists in the scent-organ of the cJ(J, a brush of hairs on the underside of the forewing between median and submedian This differs in size, shape and position in the individual species, being mostly basally — The hairs are glossy, mm long and have the tips bent pointed, anteriorly and distally rounded towards one another In most species the scent-organ stands out before the costal margin of the hindwing, in single cases, e g in geryon, it even remains hidden if the forewing is much brought forward in setting In consequence of this brush cellule b is very broad between median and submedian, up to 12 mm., and the submedian and inner margin are semicircularly curved posteriorly In the female the scent-organ is absent and the submedian and inner margin of the forewing are straight The genus is distributed from Guatemala to South Brazil through Central and South America a) In the oo the subcostal and upper radial of the hindwing arise near together but separate out of the anterior margin of the cell, converge somewhat for a short distance and then diverge strongly Hence the upper discocellular is short and only reaches '/s to the length of the middle discocellular The inner margin of the forewing In the o
