COMMON BUTTERFLIES OF THE PLAINS.

usually rounded end (where the drop of liquid rests) ; as usual, also, there are 

 longer (only slightly here however), fine, light hairs in the subspiracular 

 region and lateral ventral region -, still longer ones at the extremity of anal 

 flap where each one is also thicker and dark. The colour is a rather fine rich 

 green dorsally with, sometimes, a dorsal, clear yellow, narrow band continu- 

 ed on to the vertex of head ; the belly, true legs and claspers much lighter 

 and glaucous ; the feet lobed, the booklets brownish ; there are generally 

 three (there may be 11 of them, one on each segment 2-12 forming an unin- 

 terrupted chain, broadening out, round each spiracle upwards, always narrow- 

 est at segment margins ; sometimes suffused greyish) large patches present, 

 light pinkish-brown in colour, always margined darker, in the spiracular 

 region of segments 2, 8 and 11 ; on each segment they nearly always are 

 bordered by the front margin and stretch back, including the spiracle as a 

 very general rule, the whole breadth of the segment, encroaching on to the 

 next succeeding segment often to include the spiracle of that, generally 

 narrowest at the segment margins increasing in width towards the segment- 

 middle, reaching rarely at broadest part to more than the dorsolateral 

 region above, never stretching on to ventral region ; these patches may all 

 be small, the front one may be wanting (segment 2) and the shape is hardly 

 ever the same in any two larvee. L : 25 mm ; B : 4 mm. 



Pupa- — {Vide marginal figure). — The chrysalis is like a large Colotis amata 

 pupa in shape and way of hanging. The longitudinal 

 axis of the body is quite straight from the tip of the 

 short, conical snout to the end of segment 13, the 

 cremaster after that being slightly curved under ; the 

 thorax is slightly humped and the ventral wing-bulge 

 is quite normally convex ; the shoulders are the widest 

 part of pupa and are somewhat suddenly prominent 

 from hinder margin of segment 2 ; the lateral outline 

 of pupa — the breadth, that is, narrows very slightly 

 behind them gradually to where the body string passes 

 (the pupa is therefore very slightly constricted late- 

 rally) and then broadens again gradually to middle 

 where it is nearly as great as at shoulders, thereafter 

 gradually and evenly decreasing again to cremaster ; 

 the dorsal outline is straight from behind thorax to end 

 of segment 8, curving gradually thence to cremastral 

 extremity ; the ventral line from front of head-point to 

 end of wings, over the bulge, is 14mm of which the 

 straight portion from front ^to apex of bulge is 10mm ; 

 the ventral line of segments 9 to end is gently curved 

 towards longitudinal axis. The head point is a good 

 deal broader at base, which base embraces the whole 

 width and depth of head, than it is high, it is conical 

 with its apex bluntly rounded ; segment 2 is in even 

 continuation with the head, (or base of the point rather) is transversely 

 convex, and the front slope of thorax is again in even continuation with it, 

 the dorsal line of head, segment 2 and front slope of thorax being quite 

 straight at an angle of about 35° with the longitudinal axis of pupa ; segment 

 2 hinder and front margins are slightly bent towards each other in dorsal 

 line and its length is somewhat less than the length from end of head-point 

 to the hinder margin of head (front margin of segment 2) ; the hinder slope 

 of dorsal line of thorax is very gentle and runs imperceptibly into the dorsal 

 plane of abdomen ; the hinder margin of thorax is a somewhat gentle curve, 

 the ends of which on each side become nearly a straight line before imping- 

 ing on wing-line which they do at right angles, the actual angle being an
