PLTJSIA PULOHRINA. Ill 



segment is small and low, which makes the twelfth 

 have a raised and swollen appearance; from the 

 fourth to the head each segment becomes consider- 

 ably smaller than the one behind it, giving the ante- 

 rior of the larva a very pointed appearance ; skin 

 rough, and, as well as the head, clothed with a few 

 scattered but rather stiff hairs ; the segmental divi- 

 sions are well-defined ; and, like others in the genus, 

 there are only six prolegs. 



Ground-colour of the body and head bright apple- 

 green ; the mandibles, and a rather broad stripe 

 extending round each cheek, intensely black ; dorsal 

 line darker green than the ground-colour, and edged 

 on each side with two irregular interrupted white 

 lines ; these lines become confluent on the posterior 

 segments, and, with the white encircled tubercles, 

 give the appearance of a somewhat variegated pat- 

 tern ; there is also a very zigzag white line along the 

 subdorsal region, and a white even line above the 

 spiracles; spiracles oblong-oval, placed perpendicu- 

 larly, cream-colour, encircled with brown ; the hairs 

 have the lower part cream-colour, the tips brown. 

 Ventral surface, legs, and prolegs uniformly apple- 

 green. 



The larva rests with the anterior segments raised 

 from the food-plant and the back arched like that 

 of a Geometer, which gives it a rather grotesque 

 appearance. Like its relatives it spins a moderately 

 compact white cocoon amongst its food-plant, through 

 which the black chrysalis can be readily seen. The 

 moth emerges in about a month — that is, in the 

 middle of June. (Geo. T. Porritt, Huddersfield, 

 February 4th, 1881 ; Entom., March, 1881, XIV, 66.) 



On the 6th of May, 1876, I figured a nearly full- 

 grown larva sent by Mrs. Hutchinson, which she had 

 reared from the egg on cow-parsley, honeysuckle, etc., 

 and sent me on the 25th of April, with another which 

 died instead of spinning up. But the one which I 

 figured on the 6th of May spun itself up within a day
