Show 458 MR. A. G. BUTLER ON THE GENUS EUPTYCHIA. [NOV. 22, BRAHMCEA. By the kind assistance of Mr. Frederic Moore I have discovered that m y Brahmara petiveri is identical with B. lunulata of Bremer, figured in the third part of Menetries's catalogue, the habitat of that insect being stated as North China. B. whitei I believe goes under the name of hearseyana, which I imagine must have been the name intended for it by Mr. A d a m White, the specimen which he figured having been brought over by Gereral Hearsey.

A Monograph of the Genus Euptychia, a numerous race of Butterflies belonging to the Family Satyridce; with Descriptions of Sixty Species n e w to Science, and Notes on their Affinities &c. By A R T H U R G A R D I N E R B U T L E R, F.Z.S., Assistant, Zoological Department, British M u seum. (Plates XXXIX., XL.) The very numerous genus which I have now taken in hand has for some years remained comparatively untouched by entomologists. The species are confined exclusively to the N e w World, the majority of them being natives of South America. They are generally rather sober in colouring; but some species are exceedingly brilliant, and often varied on the underside with silvery spots and streaks which appear embossed, as though molten metal had been dropped upon the wings. Euptychia is closely allied to several other Satyride genera, from some of which it seems scarcely to differ except in colouring or locality. Professor Westwood, in the ' Genera of Diurnal Lepidoptera,' has separated it under two names, Neonympha and Euptychia, following the example set by Hiibner in his ' Verzeichniss der bekannten Schmetterlinge;' but most entomologists now agree that the two genera are synonymous. In the ' Genera,' although great trouble has been taken in dividing them, several species are placed under both heads. In the present paper I have placed the insects as nearly as possible in natural consecutive order, and divided them under sections, to render their determination less difficult. This Monograph includes all the species in the National Collection, |
