280 SPHINGID^E. 



Pupa. — Stout, head round, base of segment 12 fitting into 

 the undercut hind margin of 11 as in Acosmeryx. 



Habits. — The food-plants belong to the families Ampelideae r 

 Saxifragaceae and Ternstrcemiaceae. The larva lies stretched 

 straight out along the midrib of the underside of a leaf. 

 When molested the head and anterior segments are partially 

 retracted into the fourth and fifth segments, these two segments 

 being dilated and the lateral flanges expanded, but less strongly 

 than in Acosmeryx. The dorsum becomes suffused with brown 

 before pupation, which takes place in a rough cocoon on the 

 surface of the ground. The moths rest with the wings held 

 nearly horizontal and the abdomen straight. We have seen 

 only bred specimens. 



Hab. W. and E. Himalayas, China, Japan and the Philip- 

 pines. Five Indian species and subspecies.

The larvae and pupae are not known sufficiently well to 

 enable keys to be prepared, but the larva of k. khasiana can 

 be distinguished by the presence of a dorso -lateral line of 

 spine-like tubercles. The pupa of obliquifascia is said to have 

 two horns on the head and three at the anal end.
