PSYCHE.

171. G. Greyi, sp. nov. $. Palpi, front, 

 collar, and thorax hoary-gray; abdomen on 

 the upper side orange-pink annulated by 

 seven lines of jet black, tipped with a long 

 tuft of cream colored hair. The underside of 

 the thorax at the base of the wings and the 

 metathorax are orange-pink. The pectus and 

 lower side of the thorax and abdomen are 

 pale hoary gray. The legs have the tibiae 

 heavily clothed with dark hoary scales. The 

 tarsi are blackish. The primaries on the 

 upper side are hoary-gray like the thorax, 

 paler on the outer margins. The inner 

 margin is provided at the middle with a 

 series of long blackish hairlike scales, which 

 project outwardly and give the inner margin 

 a lobed appearance. The wing is ornamented 

 by a spot of deep black velvety raised scales 

 at the end of the cell, and is crossed by an 

 obscure denticulate sub-basal line followed 

 by a geminate more distinct waved and den- 

 ticulate transverse median line, followed 

 beyond the cell by a similar less distinct line 

 which curves outwardly and runs from the 

 costa to the inner margin at its lobe-like 

 hairy projection there apparently uniting with 

 the transverse median line. The outer 

 margin, which is broadly pale hoary gray, 

 is slightly clouded with darker brown on the 

 apex near the costa and on the outer angle 

 and is marked by a few obscure submarginal 

 brown spots. The secondaries are dark 

 brown broadly laved with orange-pink at the 

 base and on the inner margin. They are 

 crossed by an incomplete black median band 

 which runs from beyond the end of the cell 

 to the inner margin, where it coalesces with 

 a short blackish longitudinal ray situated 

 near the inner angle. This transverse line 

 is followed by a very obscure submarginal 

 dark shade. The neurations, which are 

 pale, stand out in strong relief upon the 

 darker ground of the wings. On the under- 

 side, the wings are hoary-gray with the neu- 

 rations pale yellow and standing out dis- 

 tinctly upon the darker background. The 

 contrast is made more effective on the median 



area of both wings by the clouding of the 

 intraneural spaces with dark brown, or 

 blackish. The secondaries have the inner 

 margin broadly laved with orange-pink. 



? . The prevalent color of this sex is dark 

 chocolate-brown, darkest upon the outer 

 margins of the primaries and secondaries. 

 The primaries are crossed by the same lines 

 which appear in the male, but modified by 

 reason of the different form and greater 

 expanse of the wing. The black patch of 

 raised velvety scales at the end of the cell is 

 distinct in this sex and the tufted formation 

 of the patagia which are margined with black 

 externally and sprinkled with ochraceous 

 hairs is very characteristic. On the under 

 side the costa, which is produced just before 

 the base and has its costal margin quite 

 straight beyond this projection, is clothed 

 upon its edge with long projecting hairs. 

 There is no trace whatever in this sex of the 

 broad orange-pink markings of the male.

I have two females of this species which 

 were bred by Mr. Good from larvae. He 

 exposed a virgin female in a cage and suc- 

 ceeded in assembling the males which are 

 referable to Moschler's genus Gastroplakaeis, 

 which, without a knowledge of this fact, 

 would at first glance appear to bean improb- 

 able assortment of the sexes. I take pleasure 

 in naming this beautiful species after my 

 good friend, Robert M. Grey, who is one of 

 our most ardent collectors, and who for 

 nearly a year rendered me faithful service in 

 expanding and arranging my great African 

 and Indian collections. 



Leipoxais, yen. nov. 



Allied to genus Libethra, strictly cong 

 eric with Gastropacha haetnatidea, Snell., 

 which is referred by Kirby to Libethra, 

 where, however, it does not belong, as is 

 clearly shown by the neuration. The palpi 

 are large, compressed, directed forward, and 

 heavilv clothed with hair. The antennae of
