PEACH. ROOT — THE BORER. VARIETIES. FEMALE. 115 



Sides with numerous fine short hairs, with a slight vacancy between them at each of the 

 joints. The feelers are yellow on their lower sides; there is a paler yellow spot be- 

 tween the bases of the antennae and a deeper yellow transverse stripe at the base CT 

 the bead both above and beneath. Tbe thorax has a yellow stripe on each side of its 

 middle, a transverse one at its base which is slightly interrupled in the middle, anda 

 short broader one on each side under the wings; its base on the underside is white. 

 The abdomen commonly has two slender yellow bands above, at the apex of the 

 second and fourth segments, and a white line on each side of the tnft of hairs at its 

 tip. The forward hips are yellow on their anterior face, the four others at their tips. 

 The shanks are yellow at their tips, the hind ones have a yellow ring on their middle 

 interrupted on the inner side, the other four have a large yellow spot on their ante- 

 rior sides; their spines are white, their upper sides black at least on the basal hal£ 

 The fore feet have a white ring at the apex of each joint and a broad white stripe 

 upoQ the inner side ; the middle and hind feet have a slender white line on their inner 

 sides, which is often nearly obliterated, showing only a few white scales at the apex 

 of each joint. The wings are transparent and glass-like with a slight tinge of smoky 

 yellow; their veins, margins and fringe is steel-blue. The fore- wings have a steel- 

 blue band beyond the middle upon their transverse anastamosing veinlet, a slender 

 yellow line upon their outer or anterior margin both above and below, and a similar 

 line on the inner edge of their, inner margin, the hind wings also have a similar line 

 on the inner edge of their outer margin. 



The following VARiETfES occur in this sex: 



u.. The pale yellow spot between the bases of the antennae wanting. 



b. The same spot enlarged and extending backwards to the neck. 



c. The abdomen without white stripes upon the sides of the tail. 



d. The abdomen without any yellow bands. 



e. The abdomen with but one band, that upon the apex of the. second segment 

 wanting. 



/. Three yellow bands, one on the apex of the fifth segment. Common. 

 g. Four bands, one on the apex of each segment from the second to the fifth ia- 

 clusive, that upon the third segment often imperfect. 



The FEKALE differs from the male so much that it would not be supposed to pertain 

 to the same species. The abdomen is of a long oval form instead of being slender 

 and cylindrical, and is twice as broad across the middle as that of the male. This 

 sex is of a glossy steel blue color with a purplish reflection in places and blackish upon 

 the face, and upon the middle of the abdomen is a broad band of a bright glossy 

 orange yellow color occupying the whole of the fourth and fifth segments* except 

 upon the middle of the underside, where, at least on the fourth segment some orange 

 scales often occur interspersed with the steel blue ones. The antennae have nofiinge 

 along their inner sides. The fore wings are opake and of the same steel blue color as 

 the body their tips and fringes being of a purplish tint both above and beneath. The 

 hind wings are transparent broadly margined upon both sides and marked at the base 

 with steel blue, the glass-like pordon being crossed by five robust veins, and com- 

 monly there are traces of a straw*yellow stripe on the outer margin towards the tip. 



» Say describes the abdomen as having ooly the fifth segment of an orange color, but in 

 every specimen which I have seen tbe fourth segment also is of this color.
