REPORT OF THE ENTOMOLOGIST. 207 



skins at three successive periods, and these skins are slipped on to the 

 fork, where in most intances they remain. On carefully detaching 

 from a full grown larva? the dung with which these skins are mixed, 

 these three successive skins are easily recognized, the smallest being 

 at the extremity and the largest at the base of the fork. They are 

 especially recognizable in the mottled species (Coptocycla guttata) 

 shown in Fig. 21, which removes most of its dung before each moult. 



" The eggs from which these larva? hatch, and 

 which we do not recollect to have seen anywhere 

 described, are deposited singly upon the leaves, to 

 which they are fastened by some adhesive substance. 

 They are of irregular angular form ; flat, and some- 

 what narrower at one end than the other; ridged 

 above and at the sides, but smooth and obovate be- 

 low. They are usually furnished with spine-like /' 

 appendages, which, however, are sometimes entirely 

 lacking. Those of Coptocycla aurichcdcea [shown FlG 

 greatly magnified at Fig. 17] are 0.04 inch long, and S^reatfyfiit^S' 

 of a dull, dirty-white color. [A * er Hiley] 



" When full grown the larvae fasten the last two or three joints of 

 the body to the underside of a leaf, by means of a sticky secretion, 

 and in about two days change to pupa?. The pupa is also flat with 

 usually four or five broad, but thin and transparent serrated leaf-like 

 appendages on each side of the abdomen, and the prothorax, which is 

 greatly dilated and covers the head, is furnished around the edge with 

 smaller barbed spines. The broad leaf-like spines at the edges of the 

 body are bent under while the transformation is being effected, but are 

 soon afterwards stretched stiffly out with a forward slant. The pupa 

 loses the pronged tail, but as the old larval skin is left adhering to the 

 terminal segments the prong of dung still protects it in most cases. 

 The legs and antenna? are not free in this, as in the pupa? of most 

 other beetles, but are soldered together as in the chrysalis of a butter- 

 fly, and yet it has the power of raising itself up perpendicularly upon 

 the tail end by which it is fastened. The pupa state lasts about a 

 week." 



Having given an outline of the life history of these peculiar, 

 though beautiful little beetles, I will devote a little space to each of 

 the several species that are found in the state. Since all of these in-
