inclosed within the same iris Underside as above, except that the costal margin of the posterior wing is of a much darker brown and is marked beyond the middle by an ocellus similar to the others, but smaller that the central spot is much larger, extending to the inner margin, and of a darker brown that the ocelli are much larger, especially that nearest the inner margin which has absorbed the : small ocellus mentioned above and contains two pupils Expan 3^ in In the Collection Hab Waigiou of A R Wallace It was not until after the accompanying plate was finished, and I believed that I had figured a new species, when I ascertained that it is identical with the Morpho bioculatus of Guerin It is not, as supposed by Boisduval and Westwood, the female of Melanitis (Dyctis) Agondas, from which it differs in the position of the nervures It is a Drusilla, and was placed in that genus by Dr Boisduval under the name of Hyades Indra The Dyctis bioculatus of the " Genera of Diurnal Lepidoptera," Plate LIV.* is not the Morpho bioculatus of Guerin but the true female of Agondas and not being able to discover any resemblance to the butterflies then before me in the figure given of Dyctis Agondas in the " Voyage de TAstroIabe," I figured it and a series of the females in the "Proceedings of the Zoological Society," Annulosa, Plate LV under the name of Melanitis Melane D bioculatus, though agreeing with the other characters of Drusilla, differs from all the other species or varieties in the arrangement of the discocellular nervures of the anterior wing in D Horsfieldii the first and seeond disco-cellular nervures are very short and of equal length, the third very long and curved; in D bioculatus the first disco-cellular nervure is very short, the second very long, and the third short On examining the numerous examples of Drusilla in my collection, I find that there is considerable difference in the length of the second disco-cellular nervure iu Horsfieldii, as stated above, the first and second disco-cellulars are of equal length in all the others the second nervure is three or four times the length of the first ;

and that there is a third ocellus near the incomplete Hab Aru W YV Saunders and W C Hewitson stated my belief, and I may repeat it here In the Collections of I have elsewhere (excepting D Horsfieldii from the list in consequence of its differing in the length of the disco-cellular nervures) that D Catops and Selene of Boisduval, D Phorcas and Milsecha of Westwood, D Myops and Macrops of Felder, and D Artemis, Anableps, and Dioptica of Volleuhoven, are only varieties of Urania D Dimona should, very probably, add one more to the number it differs, however, so much from all ou the upperside, that I have preferred for the present to cousider it as distinct ;
