 with yellowish. Long. corp. 0.13. L\>ng. al. 0.16. 



Very much resembling Notiph. uliginosa Hal. (which is identical 

 with Notiph. tarsata Stenh.), but its narrower face distinguishes 

 it from that and all the related European species. Palpi blackish. 

 Antennas entirely black ; front with yellowish-brown on black 

 ground. The same is the case with the upper side of the thorax, 

 which has no broad longitudinal stripes, but only a faint trace, often 

 indistinct, of five fine, brown longitudinal lines. The scutellum is 

 colored as the upper side of the thorax, but generally with a rather 

 lighter gray border and longitudinal line. Abdomen gray, with 

 broad brownish-black fasciae occupying more than the anterior half 

 of each segment, and being interrupted by a gray middle stripe ; the 

 last segment in the male is almost entirely black, and has a gray 

 middle stripe on its anterior half. Femora and tibiae black ; the 

 knees and the extreme tips of the tibiae brownish-yellow ; the fore 

 tarsi black, having the innermost base of each joint yellowish ; 

 the posterior ta?si yellowish, with the tip brownish. Wings pel- 

 lucid brownish-gray, with brown veins ; the second segment of the 

 costal vein being nearly twice as long as the third.

 dark-brown longitudinal stripe. Such a stripe runs on the upper 

 part of the pleura? from the shoulder to near the base of the wing. 

 The brown color of the lateral border of the scutellum continues on 

 the posterior border of the thorax as a short beginning of a stripe.
