head which are nearly black and one, subspiracular, on segment 2 also black. 



Srd stage. — The little larva finished moulting on the night of the 23rd 

 of the month. It had become green before it moulted from eating vege- 

 table matter. It was still green when it finished moulting though slightly 

 less opaquely so. On the 25th morning it was 11 mm. long by something 

 over 1 mm. in breadth; it was shiny green in colour, the head being tinged 

 with yellow ; on segments 2, 3, 4, 5, 6, 11 and 12 there were spiracular, 

 dark, chocolate-brown marks, just little spots on the first 3 segments, a 

 good deal larger on segments 5, 6, still larger and nearly coalescing at 

 margins on the last two, including the spiracle on the last four. The tail- 

 points well accentuated, short, diverging, separated narrowly at bases, 

 conical, covered with little erect hairs like the body though slightly longer, 

 proceeding from the somewhat flattened cremastral segment out backwards 

 and in the same plane with it. The head is round, though of course 

 truncated across jaws and that, indeed, somewhat broadly ; the clypeus 

 is large, triangular and somewhat depressed ; the surface shiny, bearing 

 many, little, brown, erect hairs or bristles all over its surface as well as some 

 few (the usual subdorsal, dorsolateral and lower ones) longer hairs from, 

 each, a light-coloured, conical tubercle ; the jaws and eyes dark in colour, 

 the labrum and ligula perhaps lighter than the rest. The surface of body 

 transversely lined as usual, covered somewhat profusely with short, erect, 

 brown hairs which do not, however, hide the surface in the least when 

 viewed from above, these hairs being disposed without order on the inter- 

 vals between the depressed lines ; there are also the prominent white, 

 conical subdorsal, dorsolateral and supraspiracular tubercles of this type 

 of larva, each bearing a longer, erect dark hair with the usvial drop of 

 liquid at its tip, though this drop may be wanting occasionally (its presence 

 seems to depend upon the state of health for it is mostly wanting in such 

 larvfe as are stinted in their food) ; some fine hairs subspiraculary which 

 are light in colour and as long as the main-tubercle ones ; there are two 

 less conical, yellowish tubercles below the spiracles ; there is a dis-tinct 

 "flange" running the whole length of larva below the spiracles and these 

 are situated upon it. Spiracles oval, of ordinary size, flush, whitish in 

 colour ; those of segments 11, 12 larger than rest ; those of segment 2 also, 

 of course, larger. The colour of the larva is light grass-green, the ventrum 

 and legs and claspers somewhat lighter still, all shiny ; the chocolate 

 spiracular markings very conspicuous, seemingly prominent-convex, shiny. 



J^tli stage. — This was successfully accomplished in the night of the 25th 

 September ; the larva was eating the cast skin on the morning of the 26th. 

 On the 28th mid-day it was full grown and then measured 17 mm. by 2 mm. 

 The head semi-elliptical, the lobes fairly well marked, the vertices of 

 lobes rounded ; the surface minutely shagreened, covered with short, 

 semi-erect, sharply and slimly conical, brown hairs, all of the same length, 

 distant one from the other about their own length (no longer vertical or 

 facial ones except a few, very slightly longer, about base) ; clypeus large, 

 triangular, same colour as rest ; labrum same colour also ; ligula whitish ; 

 jaws tipped dark brown ; eyes glassy, sometimes partially suftused brown ; 

 antennal basal joint green ; 2nd joint colourless translucent. Surface of 

 body as in last stage, the main tubercles rather less prominent compara- 

 tively with rather (also comparatively to the minute hairs) shorter brown 

 hair to each ; the whole surface similarly transversely lined and covered 

 with similar, dark brown, short hairs ; the anal segment with the points 

 rather more widely separated by an even rounded sinus in continuation 

 with the inner, lateral outline of each, the points shortly haired with white 

 and brown hairs, the subspiracular region shortly light-haired. The 

 spiracles light, thinly bordered with black, surrounded by body-colour
