 Hab. \\'yoming, June, Dr. Wllliston. 



Tet. lineata, sp. nov., ^ . Bristles of the antennre nearly bare, 

 wings not reticulated, posterior transverse vein very strongly doubly 

 curved, so that the middle half is parallel to the fourth longitudinal vein. 

 Long. Corp. 6 mm. Long. al. 5 mm. 



Pale brownish. Front obscure yellowish, with the median polished 

 stripe tapering anteriorly ; on each side near the orbit is a small leddish 

 spot, and more anteriorly, between the base of the antennae and anterior 

 corner of the orbit, a larger reddish spot with a dark centre. Antennae 

 nearly the color of the front, the second joint covered with small black 

 hairs, the third joint as long as second, scarcely excised and obtuse; basal 

 half of the bristle concolorous with the antenna, terminal half slender, 

 whitish, and microscopically pubescent. Face gently receding, light yel- 

 lowish. Thorax with a median reddish-brown stripe extending over the 

 scutellum, divided in its anterior part by a narrow whitish line ; on each 

 side a stripe dusted with, white extending over the side of the scutellum ; 

 laterally on each side there is another irregular brownish-red stripe bor- 

 dered by whitish in front of the wings. Pleurae with brownish stripe, 

 extending to beneath the poisers. Abdomen brown with paler lateral 

 borders and narrow posterior margins of the segments. Legs obscurely 

 yellowish-brown, hind femora with a number of short spine-like bristles 

 underneath the distal halves ; tarsi blackened towards their tips. Wings 

 yellowish-hyaline, with irregular brownish clouds in the end of the sub- 

 marginal, most of the first posterior and middle of discal cells ; posterior 

 margin of the wing greyish. Transverse veins clouded with brown, the 

 posterior one strongly curved, its middle portion parallel to the fourth, and 

 its terminal portions perpendicular to the fourth and fifth longitudinal 

 veins. 



Hab. Connecticut, Dr. Williston. 



An easily recognizable species with characters approaching somewhat 

 the genus Sepcdon. 



Sepedon fuscipennis Lw. Specimens from Washington Territory can- 

 not be distinguished from New England ones. In all, the lateral frontal 

 spots are more commonly absent, and the tarsi may show but a faint 

 degree of blackening in their ground color. Long. corp. 5.5-8 mm.
