CLANIS. 155 



a subdorsal and a subspiracular stripe formed of large tubercles 

 on 2 to 5, the latter joining the lower end of the oblique 

 stripe on 5 ; oblique stripes formed of large tubercles on 

 5 to 11, each running back to near the dorsal line, that on 

 11 running across 12 to base of horn, and formed of larger 

 tubercles than the rest ; large tubercles on horn, anal flap 

 and claspers. 



Coloration. — Head glaucous bluish-green, the tubercles 

 whitish ; labrum and ligula glassy-white ; antenna whitish ; 

 mandible pale pink, the tip shortly black. Body pale green 

 or dark yellowish-green, the small tubercles white, the large 

 ones forming the stripes yellow, those on anal flap and claspers 

 rose-coloured. Horn green ; true legs pink, the outer sides 

 dark brown ; prolegs and claspers green ; venter glaucous- 

 green. Spiracles broadly oval, bluish-green with a narrow 

 oval, depressed, central longitudinal, area green. Length 

 110 mm. ; breadth 15 mm. ; head 12 mm. long by 10 mm. 

 broad ; horn 1 mm. 



Pujja. — Surface shining, head smooth, segment 2 and wing- 

 cases superficially, transversely, coarsely corrugate ; segment 4 

 smooth ; front margins of 5 to 12 slightly tumid and coarsely 

 pitted except on venter ; ante-spiracular ridges on 9 to 11 in 

 the form of six narrow, parallel ridges, separated by channels. 

 Spiracle of 2 covered by a short, rounded lobe, sunken behind, 

 raised in front, projecting from the front margin of 3 into a 

 corresponding concave emargination of the hind margin 

 of 2, the whole dull and minutely shagreened ; the remaining 

 spiracles narrowly oval, flat, raised, with a narrow, shining 

 rim. Cremaster wedge-shaped, short, surface very coarsely 

 rugose and ending in a narrow, shining, longitudinal ridge. 

 Colour chestnut, the tumidities at the front margins of the 

 abdominal segments, spiracles and cremaster black. Length 

 68 mm. ; breadth 18 mm. 



Habits. — Food-plant : Pterocarpus 7narsupium Roxb., a 

 large tree of the family Leguminosae. The larva may pupate 

 in a month or so, but frequently lies up as a larva for eight 

 months or more, and may even come to the surface again and 

 pupate there. The pupa, if touched, wriggles and makes 

 a slight hissing noise (by rubbing the ante-spiracular ridges 

 against an opposing surface ?). We have never known the 

 moth to come to light nor have we ever come across it in the 

 wild state. The captive females have never attracted a wild 

 male, though often exposed in the hope of their doing so. 

 The bred moths which emerged soon after pupation were paler 

 in colour than those which emerged after a long period.
