BOMBYCIDjE. 



dark line beyond the discocellulars ; an erect postmedial line ; one 

 or two doubly curved subniarginal lines ; a large chocolate apical 

 patch. Hind wing darker ; inner margin chequered brown and 

 white ; a slightly curved subinarginal line. Underside of hind 

 wing with postmedial and submarginal lines. 



Abdomen in some specimens with first and last segments dark. 



Larva mottled and streaked with yellow, brown, and black ; the 

 first three somites very much swollen ; paired dorsal spines on 5th 

 to anal somite. 



The larva described by Hutton as bengalensis was probably a pale 

 variety of the common form, from which it differed in being 

 whitish, marbled with yellowish red and black ; the moth men- 

 tioned in connection with it was evidently Bombyx mori.

Head and thorax ash-coloured. Abdomen and wings rusty red ; 

 fore wing with some faint bluish marks near outer margin. 



This species is certainly either a Bombyx or Theophila, and pro- 

 bably the latter, having the outer margin of the fore wing angled.
