DREPANULID.^. 77 



Concerning this species, Sir George Hampson writes : " In 

 American and European specimens, the palpi are minute and 

 porrect ; the hind tibice have two pairs of spurs ; fore-wing 

 with vein 7 separate from 8, 9, 10. In Himalayan specimens, 

 the palpi are absent ; the hind tibiae have but one pair of 

 spurs, and vein 7 of the fore-wing is bent upwards, and almost, 

 or quite, anastomoses with 8, 9, 10." Many entomologists 

 would certainly be inclined to regard such differences as amply 

 sufficient to separate two species, if not to indicate them 

 as belonging to different genera, notwithstanding external 

 similarity in shape or colour. 



Exotic Genera of Drepanulid^. 



Cydidia (Guenee) includes some large Indian and Chinese 

 species formerly classed with the Geo/neirce. The type, 

 C. substigviaria (Hiibner), which is common throughout 

 Northern India, measures two inches and a half across the 

 wings, which are varied with white, grey, and brown. There 

 are two zig-zag lines towards the base of the fore-wings, and an 

 oblique dark line runs from the ti}) to the middle of the inner 

 margin, outside which are two or three black spots above the 

 inner margin. There is also a sub-marginal row of black dots 

 on all the wings, and a large black spot at the end of the cell 

 of the hind-wings, most conspicuous on the under-surface, 

 which is whiter than the upper. The insect resembles a 

 gigantic species of Diepana in general shape and colour. 



Miuiallo aniilia (Cramer) is a common South American 

 moth, which measures about two inches across the wings. 

 The antennae are strongly pectinated, and the abdomen is 

 moderately stout, and extends a little beyond the hind-wings. 

 The fore-wings are narrower than in Cydidia ; the costa is 

 somewhat arched, and the tip slightly falcate. The wings aie
