lepidoptera (Or those which are moths in the perfect state.) 



28. JEgerla exitiosa, Say. The Peach-tree borer [See page — .] 



This borer is very different in character from those we have been 

 considering, as it has sixteen legs, three jointed or true legs on the 

 first three segments, four pairs of abdominal legs on the sixth to the 

 ninth segments, and one pair on the last segment. 



It is a naked, soft, white, cylindrical grub, slightly flattened on the 

 under side, and, when full grown, measures something over half an 

 inch in length. 



Its head is a shining, yellowish-red color, marked in front with black, 

 and at the base and middle with white; the thorax is also white. 

 There are a few scattered brownish hairs on the head and other seg- 

 ments. The pro-legs are very short, scarcely protruding below the 

 general surface. 



When fully grown, it spins for itself a cocoon or follicle of silk, 

 mixed with the gum and excrement, wherein it passes the pupa state. 

 This follicle is of a brown color, oval in form, with the ends rounded, 

 and is about three-fourths of an inch long, or a little less, and about 

 one-third as broad. 



The perfect insect is a very pretty moth, the male and female dif- 

 fering so materially that they would be taken for different species.
