Another description of the same, made at a later date, is as 

 follows : — 



Egg. — It is very flat, turban-shaped, white in colour. Surface covered 

 with very irregular, fine, filiform reticulations connecting coarse crater-like 

 risings on the perpendicular sides ; none of these prominences on the flat 

 top where the reticulations are numerous, forming a mass of small, irregular 

 cells which are very minute in centre. B : 0*5mm ; H : 0-25mm. 



Larva. — Normal in shape. Head small, round, shining black, the neck 

 rather long ; hidden under segment 2 in repose ; segment 2 rather narrow, 

 parabolic in shape, well distinguished from the 3rd, the 4-8ided dorsal de- 

 pression not much lower than the rest of surface ; the whole body semi- 

 circular in transverse section except at the two ends, the segments well 

 marked ; anal end flattened in the usual manner, gently sloping from the 

 longitudinal axis of body, somewhat squarely rounded at extremity ; the 

 mouth-shaped gland on segment 11 and organs on segment 12 present; the 

 former rather large and, as usual, transverse ; the latter circular, occasion- 

 ally protruding long, gi-eenish cylindrical tubes simultaneously, each tube 

 again protruding a long brush of white hairs which is flourished rapidly 

 round and round, and withdrawn again to sink back, together with the 

 tube, into the body. The surface of the larva is covered with minute star- 

 shaped, bristle-bearing, white tubercles ,• the bristles brown or white, some 

 longer than others ; there are also some sparse, brown-ringed, white dots 

 which are in clusters only round the spiracles and round the gland, being 

 elsewhere scattered very sparsely except on segment 2 where there are 

 sometimes also many ; the bristles are not very short ; the margin of the 

 larva are set with rather long, soft, white hairs. Spiracles are flush, small, 

 circular and yellowish in colour. Colour of caterpillar is grass-green with 

 a dark-green dorsal line and an indistinct, diagonal, lateral, white line to 

 each segment. L: 9-25mm; B: 3mm. 



Fupa. — Is normal in shape ; rather narrow, broadest about segment 8, the 

 thorax moderately humped, the constriction behind it dorsally moderate, 

 laterally m7; segment 2 slightly emarginate on the front margin, showing 

 the vertex of the head slightly, the whole segment squarely semi-circular, 

 the dorsal slope the same as that of the front slope of thorax ; the anal end 

 rounded, the last segment turned under. <S'«//ace smooth, covered sparsely 

 with moderately long, erect, colourless hairs which are longest at the two 

 extremities. Spiracles of segment 2 linear, raised, white ; the rest slightly 

 broader, also linear, white, raised. Colour green with a double, dorsal, 

 blackish line on thorax ; a dark-green dorsal line on abdomen ; a black, 

 lateral spot on segment 5 and a black spot on point of shoulder both these 

 small. L : 6mm ; B: 2-75mm; H : 2-25 at thorax. 



In the larva there are, on segment 3, many more long, brown, 

 erect, slightly cm-ved, dorsal hairs than on any other segment ; the 

 two sub-dorsal, long (the longest of these is as much as 0-35mm., 

 in length) hairs on segments 7-10 mentioned in the first description 

 are supplemented by several other, shorter ones on each side ; so 

 are also the four on the other segments ; the hairs at both ends of 

 the larva are slightly more numerous than anywhere else ; some 

 of the dorso-ventral hairs (marginal fringe) ai-e strong and brown in 

 colour; the "brown-ringed, white dots" round the gland are, 

 really, tiny, longish, rounded, glassy tubercles and may be quite 

 wanting about the spiracles ; the diameter of the shortly -stemmed 

 stars is about 0-05mm, and some of surmounting bristles are about
