been mentioned before as being of use for the other families. The 

 coloured plates accompanying the letterpress are not very good, but 

 will be found better than nothing ; many larvae and pup^ are 

 depicted including 18 Hesperidce. 



The following is a classification of the known larva? ; — 

 A. — Larvae generally more or less brightly coloured ; the 

 skin opaque, not translucent looking ; the pattern 

 both longitudinal and transverse. 



a. Larvae with the dorsal area chiefly velvet-black with 



longitudinal yellow and blue lines as well as yellow, 

 transverse lines and the head red and black ; 

 or with the ground-colour greenish-white with 

 broad, black transverse bands and head orange 

 spotted black 

 a\ Colours black, yellow and blue, the black appear- 

 ing on sides as oval patches ; head red and 

 black . . . . . . . . . . . . Genus Bibasis. 



One species only; the pupa stout, pinkish in colour with isolated, black mark- 

 ings and covered with a white powder ; with an oval, bare, greenish patch 

 occupj'iug the middle of thorax . . . . . . . . . . Soia. 



b^. Colours as in Bibasis sena except that the black 

 on sides is continuous and does now show in 

 oval patches, with the head similarly red and 

 black ; or colour greenish-white with broad, 

 black transverse bands and head orange with 

 black spots . . . . . . . . . . Genus Ismene. 



a". Colour exactly as in Bibasis sena . . . . fergussoni. 



b". Colour greenish-white with broad black cross- 

 bands ; head orange with black spots . . . . gomata. 



Pupge as in Bibasis sena ; that of fergussoni exactly alike except that it is 

 stouter, larger ; that of gomata much lighter, greenish-white with black markings. 

 Larvae of Ismene fergussoni and Bibasis sena feed upon Combretum eztensmn, 

 that of gomata upon Heptapleurum venule sum belonging to quite a different 

 family. 



b. Larvaj dorsally suffused with mauve of a dark shade 



or bluish-green approximating to that colour ; 

 the head never red and black-patterned nor 



orange spotted with black Genus Hasora. 



a\ Larvse with no yellow, longitudinal lines ; spira- 

 cles white alexis. 



b\ Larvae with yellow longitudinal lines from seg- 

 ment 2 backwards. 

 a-. Larva with the double, sub-dorsal, yellow line 

 on each side of the dorsal line ill-defined ; a 

 spiracular, white line. Spiracles light-yellow, badra. 

 b". Larva with the sub -dorsal lines rather broad, 



well defined ; a supra and sub-spiracular line, chabrona. 

 C-. Larva with the sub -dorsal lines finer; only a 



sub-spiracular, yellow line . . . . • • butlen. 



The spiracles of these last three are all yellow ; badra can be distinguished 

 also, by having many black, transverse lines. The pupse are very similar to 

 each other, of the type of Bibasis and Ismene ; green in colour, powdered with 

 white powder ; the " boss " between the eyes rather sharply conical. The 

 piracies in badra, butleri and chabrona are black ; those of alexis are yellow.
