59. Endropia gracilis, n. sp. (no. 502). 



Wings subangulated, above pale sandy brown, speckled 

 with grey and black dots ; a larger black dot on the discocel- 

 lulars ; an irregularly edged straight discal greyish fuscous 

 stripe : primaries with a second interrupted angulated stripe 

 limiting the basal area ; costal margin up to the angulated 

 stripe blackish ; a blackish pyriform spot upon the outer 

 margin just below the apex : thorax white, with blackish 

 shoulders and brown anterior margin ; head and collar orange ; 

 abdomen pale sandy brownish speckled with black dots. 

 Under surface bright stramineous, the wings speckled and stri- 

 ated with dark brown ; the indistinct stripes of the upper 

 surface replaced by dark brown ones, the discal stripe being 

 placed upon a diffused ferruginous band : body whitish, with 

 the tibia; and tarsi stramineous, bases of the tibial spines 

 black. Expanse of wings 1 inch 4 lines. 



60. Endropia abjecta, n. sp. (no. 366). 



Pale testaceous, tinted with pink, mottled and speckled with 

 grey : primaries with the apical two fifths bronzy brownish ; 

 two transverse externally white-edged ferruginous lines — the 

 inner one at basal third straight, the outer one, which crosses 

 the disk obliquely, abruptly angulated towards apex ; a tri- 

 angular costal lilacine patch between the outer line and the 

 apex ; a ferruginous discocellular lunule : secondaries crossed 

 by a central line similar to those of primaries ; a slightly 

 irregular grey discal line : body greyish. Under surface saffron- 

 yellow, mottled with rose-colour, with bright rust-coloured lines, 

 as above in shape ; legs orange. Expanse of wings 1 inch 

 8 lines. 



I find, from an examination of specimens in Mr. Moore's 

 collection, that my genus Thiopsyche will have to sink as a 

 synonym of Walker's Corymica, the type of which is a 

 Bornean species formerly in Mr. Saunders's collection and now 

 in the Hope Museum at Oxford. Mr. Pryer has sent the 

 female of G. Pryeri. 



Amphidasida?. 



61. Biston robustum, n. sp. (no. 333). 



Wings above smoky brown, with pink reflection, irrorated 

 with black, crossed by three angulated and sinuated black 

 lines, two of which are parallel and discal, the third crossing 

 the discoidal cell and very indistinct upon the secondaries; 

 primaries with an abbreviated central interrupted black stripe; 

 secondaries paler than primaries : thorax blackish ; the head,
