102 [October, 



8th, another batch of larvae reached me from Mr. Eletcher, which he 

 had found in abundance on lichens on hawthorn twigs. The specimens 

 were smaller and evidently younger than those from the oak-post 

 lichens, but on a close examination I felt sure they were of the same 

 species, as they appeared to differ only in the broad, transverse, whitish- 

 grey streaks on each segment (described further on), seeming closer 

 together, forming, indeed, a somewhat heart-shaped mark. Both lots 

 of larvae proved to be those of ^cojparia cratcegalis. Specimens of the 

 first batch I described on April 7th, as follows : — Length, about half 

 an inch, of moderate bulk when at rest, but appears rather slender 

 when crawling ; head aud frontal plate highly polished, the former has 

 the lobes rounded, and is narrower than the second segment, into 

 which it can be partially withdrawn; each segment is plump andi 

 conspicuously divided from its neighbours by the deeply cut divisions,! 

 and these, with the large raised glossy tubercles, give to the skin a 

 somewhat rough appearance. 



Ground-colour dark olive-green, throwing into rather striking 

 relief two whitish-grey, or cream-coloured, transverse streaks on eaclt 

 segment, the front streak being broader and larger than that behinc 

 it. On these streaks are situate the intensely black tubercles, which 

 being as broad as the streaks, appear to divide them into sections 

 and the streaks are further divided by the dark, fine, thread-likf 

 dorsal line : there are no perceptible sub-dorsal lines, but an irregula 

 greyish stripe extends along the spiracular region, and on each segmeD 

 below this line is a small black spot : head and frontal plate, like th 

 tubercles, of intense glossy black ; the small spiracles also black. 



Ventral area and pro-legs dingy dark olive-green, and on tl 

 outside of each of the latter a black spot ; anterior-legs encircled witj 

 black. 



They grew very slowly, and it was not until the beginning 

 June that the last were full-grown. They were then nearly thre 

 quarters of an inch long : the dorsal area had the ground-colour of 

 paler olive-green, but in other respects was the same as when describ' 

 in April. Ventral surface and pro-legs olive-green ; the 5th and 6 ., 

 segments had each three transverse black spots, and similar spots, b! 1^ 

 smaller and more irregular, occurred on others of the segments ; ' 

 black spot on the outer side of each pro-leg; the anterior-k' , 

 encircled with black. )
