Notes on insects bred from the Prickly Ash, 



( Xan tho.rj/lum americanuvi). 



May 2bth, 1868. — This morning I passed by a small grove of Prickly Ash, a 

 mile west of this town, and observing that the wookpeckers had attacked the 

 branches of some dead trees, the trunks of which were barked last July, I made 

 an examination, and found that the bark had been considerably undermined 

 by wood-boring larvas. This work had been done during the latter part of last' 

 summer; in the autumn the borers entered the wood, usually by oblique paths, 

 to secure safe winter quarters. On cutting down I found the larvw — footless 

 borers — of whitish and pink-orange colors, about one-fourth of an inch long. In 

 these burrows I found several pink-orange pupae, invariably lying with their 

 heads outward; their long antennae folded over the wing-cases, oblique down on 

 the sides, passing beneath the posterior pair of legs, a little beyond them, and 

 then curving up over the breast reach the head. From these pupae I bred a 

 small Lamiide, related to Liopus alpha. 



Lioi'i's XANTHOXYLi, n. sp. — Gray, with bands and spots of blackish pubescence. 

 Antennae about once and a half the length of the body, joints blackish at the 

 articulations ; hoary, mottled with cinereous and light brown between. Ely- 

 tra hoary-einereous, or slightly shaded with light brown, marked with an im- 

 perfect broad transverse band before tlie middle, and with two oblique bands, 

 and many smaller spots of blackish behind the middle; in some specimens the 

 grey predominates, in others black; in a few the bands are almost obsolete, 

 being merely spotted with black. Thorax with two broad longitudinal lines 

 converging to a point in form of the letter V ; each side behind the middle with 

 an angular spine-like projection. Head depressed between the antennae, grey, 

 with some small black spots; on the occiput a posterior median half line, and 

 many small black spots, not equally well defined in all specimens. Beneath 

 cinereous, incisures blackish; legs grey, somewhat spotted with black. Length 

 about .25 inch.
