182 SPHINGID^. - 



antenna shorter than fore leg, which reaches to middle of 

 wing-case ; mid-leg reaching to about two-thirds the length 

 of wing-case. Surface of head, thorax and wing-case very 

 superficially corrugate-aciculate ; abdomen obscurely corru- 

 gate, the front quarter of each of segments 5 to 12 very 

 deeply, coarsely, longitudinally pitted and corrugate ; one 

 ante-spiracular ridge on the front bevel of 9, with a channel 

 behind it ; 10 with a similar but smaller ridge and channel, 

 and 11 with the ridge and channel nearly obsolete. Spiracle of 

 2 indicated by a slit at the junction of 2 and 3, the hind 

 margin of 2 being raised in front of it, and a narrow up-tilted 

 lobe projecting from the front margin of 3 bordering the slit 

 behind ; the other spiracles parallel-sided, the ends broadly 

 rounded, the whole slightly raised, with the central slit depressed, 

 Cremaster triangular in shape, broad at base and ending in 

 a short, oblong, minutely bifid tip ; the upper surface very 

 coarsely longitudinally and transversely corrugate and 

 pitted ; the whole surface shining. The clasper scars on seg- 

 ment 14 prominent ; in the £ pupa the sex -mark on 13 nearly 

 as long as that segment ; round, with thickened lips and 

 a depressed central slit ; in the 9 pupa the sex-marks consist 

 of a depression in the middle of 12 and a pit in a forward 

 prolongation of 14 which runs across 13 to near the middle 

 of 12. 'Colour dark red-brown, the frontal ridges and the 

 tumid anterior portions of the segments darker ; spiracles 

 and cremaster black. Length 47 mm. ; breadth 16 mm. 



Habits. — The food-plants belong to the families Malvaceae 

 (Bomhax, etc.), Sterculiacese (Sterculia, etc), Tiliacese (Grewia 

 of various kinds), Euphorbiaceae (Bridelia of various kinds) 

 and Sapindaceaa (Schleichera trijuga Willd.). When large the 

 larva usually eats straight across the leaves. The pupa, 

 when touched, moves the tip of the abdomen round and 

 round, and also makes a shivering motion by rapid contractions 

 and expansions of the abdomen. The moths do not appear 

 to be attracted by light ; we have not observed them feeding, 

 for which the tongue is not well adapted. They do not mate 

 readily in captivity and wild males do not come readily to 

 bred females.
