Imago. — $ $. Difficult to distinguish from rafflesi, but usually 

 less red ; first segment of palpus paler, the white line less 

 distinct. Hind wing red, base not black ; a clayish subanal 

 patch. Expanse : ^9 50-68 mm. 



cJ. Tenth segment (fig. 105 J) as in rafflesi, but the apical 

 hook of the sternite obviously longer. Process of harpe 

 (fig. 105 K) stout, rounded at end, with a long dorso-apical 

 tooth curved towards the clasper. Penis-funnel elongate- 

 triangular ; penis-sheath as in rafflesi, but the left side with 

 more teeth, which are either simple or divided.

Fig. 109. — Hippotion boerhavise (Fabr.). 



$. Edges of vaginal aperture less raised than in rafflesi. 



Hab. W. and E. Himalayas, S. India and Ceylon to S. 

 China, Malaya and the Philippines. We have bred the species 

 in S. India, where it is common in open country, and in the 

 W. and E. Himalayas, where it is less common. Mell has 

 bred it in S. China. 



Egg. — Broadly ovoid, surface shining and smooth, colour 

 bright green. 



Larva : — 



Final instar. Head round ; clypeus equilaterally triangular, 

 one -half the length of the head ; false clypeus forming a fairly 

 broad arch over apex of true clypeus, reaching to two -thirds 

 length of head ; labrum one -half length of clypeus ; ligula 

 longer than labrum, its outline square ; cutting-edge of mandible 

 coarsely toothed ; eyes 1 to 4 forming a semicircle, 6 in line 

 with 3 and 4 ; 1 to 4 equidistant, 6 twice as far from 4 as 4 is 

 from 3 ; 5 closer to 4 than to 6. Surface of head dull and 

 smooth. Body shaped as in others of the genus, with dull and
