anal flap green dotted with white. Spiracles orange with the 

 ends white. 



In another form the head is black ; body black dotted 

 with white, dorsum brownish, violet-brown or drab ; the 

 longitudinal stripes sometimes broken or wanting ; horn and 

 true legs shining black ; venter pinkish. 



These are the principal colour-forms, but intermediate 

 forms also occur, and all are subject to variation. The only 

 constant marking is the dorso-lateral stripe. Length 40 mm. 



Pupa. — Shape the same as that of other macroglossine 

 pupae ; tongue -sheath not very prominent ; tip of tongue 

 rounded and depressed ; antenna slightly longer than fore 

 leg ; a short narrow coxal piece. Surface moderately shining ; 

 head, thorax and wing-case very shallowly, irregularly corru- 

 gate, veins of wings raised; abdomen pitted except for a narrow 

 band near the hind margin of each ; no sculpturing on seg- 

 ment 4 ; front bevel of 9 with a number of short, closely 

 set ridges. Spiracle of 2 a narrow slit, with a raised oblong 

 transverse lobe projecting from 3 behind it, and an emargina- 

 tion of the hind margin of 2 in front of it ; remaining spiracles 

 oval, slightly raised. Cremaster triangular, tip narrowly 

 truncate, a small pointed tubercle at each lateral angle of 

 the truncation ; ventral surface slightly hollowed longitu- 

 dinally and with a rounded central keel. Colour degraded 

 greenish- white ; wing-case covered with leaden-grey reticula- 

 tions ; tongue, antenna, legs and veins of wings rusty ; 

 thorax with a leaden-grey dorsal stripe and an obscure rusty 

 dorso-lateral stripe ; abdomen with a diffuse dark dorsal 

 stripe and suffused with pinkish rust- colour ; spiracles black, 

 the central slit orange -brown ; cremaster black. Length 

 30 mm. ; breadth 8' 5 mm. 



Habits. — Food-plants : Strychnos nuxvomica Linn, and other 

 species of Strychnos, family Loganiacese. The full-fed larva 

 when alarmed raises the front part of the body, throws the 

 head back over the dorsum, and ejects green fluid from the 

 mouth. Before pupation it turns a livid pinkish colour. 

 The moth makes a deep humming note before flight by 

 a quivering motion of the wings. It does not appear to be 

 attracted by light.
