LEPIDOPTERA. 



Female in appearance a mere maggot. Head small, brown, 

 horny, very smooth and shining, rounded in front, and with- 

 out mouth-organs or eye-lobes, but with a dark spot on each 

 side and a paler one above, and very short, glassy indications 

 of the antenna?, which are mere portions of the hard mask 

 which forms the head. Second and third segments each with 

 a large, convex, shining, dark brown horny plate, extending 

 down the sides, where it becomes more red-brown ; fourth 

 segment with a smaller paler plate. Body fat and maggot- 

 like, pinkish-white or pale brovvnish-piuk ; devoid of scales, 

 having a faintly brownish indication of a double dorsal line, 

 a single row of round red-brown dots along the middle of the 

 ventral surface, and slight ridges across the lower side of 

 the anterior segments. Anal segment with a short, bluntly 

 projecting ovipositor-sheath, and beneath it two rounded 

 papillae. At the sides of the seventh to ninth segments are 

 small tufts of erect, soft white hairs. This description 

 applies only to the living and freshly emerged female. 

 When preserved it shrivels into a wrinkled and shapeless 

 object of a reddish-brown colour. 



End of March, April, and probably May. 



Larva pale grey, whitish beneath, apparently quite desti- 

 tute of hairs ; head shining black, jaws dark brown ; second, 

 third, and fourth segments each with a rather narrow dark 

 grey horny plate which almost embraces the segment, having 

 a blackish dividing line down the middle of the back and 

 whitish spots on the sides ; legs large and well developed, 

 brown, with the claws black ; prolegs minute, except the 

 anal, which are small and coloured as the body. In a case, 

 one inch in length and moderately thick, composed internally 

 of soft, tough silk, and covered externally with small pieces 

 of dried grass all pointing backward, morsels of bark, seed- 

 capsules and other dried vegetable morsels. 



When very young it seems to dift'er but little from the 

 adult larva, but is dirty yellowish-white, with black head;
