THERETRA. 443 



Pupa. — Tongue-sheath much projecting in front of head ; 

 fore leg reaching to about the middle of wing-case, antenna 

 slightly longer ; mid-leg to about three-quarters the distance 

 to tip of wing-case ; a narrow coxal piece ; the hind margin 

 of segment 11 slightly undercut and overlapping the front 

 margin of 12. Surface moderately shining ; tongue-sheath 

 with a narrow mesial channel, sides with wide radial corruga- 

 tions ; head and thorax coarsely, superficially shagreened, 

 wing-case smooth ; abdomen more finely corrugate ; seg- 

 ment 9 with about twelve ante-spiracular ridges, more or less 

 parallel, but anastomosing in places ; 10 and 11 with fewer 

 and less prominent ridges ; dorsum of 14 deeply pitted. 

 Spiracle of 2 a narrow slit nearly covered by a transverse 

 oblong lobe projecting from the front margin of 3, the front 

 edge of the lobe raised, hind edge depressed ; remaining 

 spiracles oval, with very thick raised rims. Cremaster 

 triangular, ending in two short, conical, divergent teeth, 

 their bases touching ; upper surface convex and longitudinally, 

 irregularly ridged, lower surface with a broad mesial ridge 

 and lateral extensor-ridges, the whole very rugose ; seg- 

 ment 14 shallowly hollowed under base of cremaster. Colour 

 dull ochreous ; tongue-sheath reddish-brown ; head, thorax 

 and wing-case mottled with blackish in lateral area ; abdomen 

 with a very obscure greenish dorsal stripe ; hind bevels of 

 segments 8 to 11 chocolate, front bevels of 9 to 11 pinkish ; 

 spiracular and ventral regions speckled and striped with 

 brown ; spiracles and cremaster black. Length 69 mm. ; 

 breadth 13 mm. ; tongue-sheath projecting 8 mm. in front of 

 head. 



Habits. — Food-plants: Dillenia indica Linn., family Dilleni- 

 acea3 ; Saurauja nepalensis DC, family Ternstroemiacese ; 

 Vitis Linn., Leea Linn., family Ampelidese ; Psychotria Linn., 

 Bubia cordifolia Linn., family Rubiaceae. The head and anterior 

 segments of the larva are more strongly retractile than in the 

 previous species. The pupa is not attached to the inside of 

 the cocoon. The moths are frequently caught visiting flowers, 

 and are also attracted by light.

Imago. — 2. Nearly related to T. alecto and T. sujfusa, 

 closer to the former species. Head and thorax dark brown 

 with no dorsal line ; side-stripe on head and thorax as in 

 alecto, but duller in colour, with a pink tinge. Fore wing 

 wood-brown ; a darker marginal band from apex to hind 

 angle, widening evenly to this angle, where it is 9 mm. in 

 width ; this band formed from three lines, the distal wider
