Pupa. — (PI., 2, fig. 20a), — The shape of the pupa resembles that of 

 Pareronia far more than any other ; it is not in the least like the other Colotis 

 species ; it has the ventral wing-bulge extremely accentuated and a long 

 generally upwards-curved, sometimes somewhat twisted, snout to the 

 head. The portion of the body composed of segments 1-4 is thrown back 

 at an angle of about 30° to the rest, the snout counted from the head- 

 frons is as long as the distance from the same place or point backwards 

 to the apex of thorax "hump " : it is 3 mm. or slightly more in length and 

 is directed forwards (or down as the pupa generally hangs) in exactly the 

 same straight line as the ventral line of the pupa from segment 1 to apex of 

 wing-bulge opposite segment 7 ; the snout is longly conical, not always 

 straight throughout its whole length but often curved towards dorsum of 

 pupa, sometimes bent to the side into the margin in its distal part, its basal 

 diameter is less than that of head and the lateral contour of pupa from it 

 to shoulders is a gradually widening triangle ; from shoulders back to 

 segment 8 the lateral Jines very gently converge towards each other again 

 and there is a slight constriction in the otherwise straight line of the slight 

 lateral wing-expansion at the place where the body-band or suspension-loop 

 passes ; the abdomen is more or less circular in transverse section, rather 

 short and stout, gradually thinning to end where it finishes off in a rather 

 broad, trapeze-shaped cremaster which is as broad as long for the last half 

 of its length, is convex transversely over dorsum, has thickened lateral 

 margins, two dorsal ridges from the hinder lateral corners converging forwards 

 to nearly meet in dorsal line at front margin and two ventral extensor ridges 

 ending each in a minute, free, sharp tooth anteriorly. Segment 2 is as long 

 as half thorax-length and has its two margins (front and hinder) curved 

 considerable towards each other in dorsal region (where it is thus narrowest) 

 it is convex transversely and its dorsal plane inclines gradually away from 

 longitudinal axis of pupa towards thorax ; the thorax is not very prominently 

 humped, the apex of the hump (which hump is evenly rounded) is just 

 behind the middle of its length, hinder margin is a gentle curve meeting the 

 wing-line in an angle of 90^^ open and sharp. The sjnracle of segment 



2 is just a linear indication which is quite straight and has a very slight 

 white, narrow, raised surface behind it on the front margin of segment 



3 ; other spiracles are nearly white, oval, perhaps rather large, flush. The 

 surface of the pupa is rather coarsely shallow-pitted, irregularly impressed- 

 lined and tuberculate-corrugated (of course vei-y shallowly and only visible 

 under lens) on the wings and segments 1-3 ; the antennse (which by the way 

 in these pupse reach only to apex of wing-bulge) are serrated along their 

 edge (characteristic of this species) with little sharp teeth ; the snout is very 

 tuberculate-rugose. The colour is glaucous green with a yellow shade, the 

 lateral wing-line from shoulders, continued along abdomen to cremaster, 

 yellow-whitish, the whole surface vermiculated with little short, whitish 

 lines or marblings ; a black spot on discocellulars of wing, a few faint ones 

 towards middle of inside margin of antennse ; and there may be a lateral 

 black dot on each segment dorsally as well as a dorsal line at hinder margins 

 of segments 8, 9. The colour may be darker green ; then the wing-margin 

 is yellow ; the colour may be light yellowish brown marbled and blotched 

 with white and darker brown. L : 17 mm ; B : 4 mm ; H at apex of wing- 

 bulge : 6 mm. nearly. 



Habits. — The eggs are laid single, often on a dead thorn or stick ; 

 the larvsB live generally on the underside of the leaves ; though 

 sometimes in the middle of upperside, sit sometimes with the front 

 segments very much in the air, occasionally with the tail end also 

 raised. They are sluggish and drop, curling up, when disturbed.
