Resembles Athysanus obsoletusin general shape- but 

 with a more produced vertex and very long elytra and wings, 

 these extending considerably beyond end of abdomen. Length 

 of female 5.5 mm. 



Vertex produced, angulate in front, one and one half to one and 

 three fourths times as long at middle as at eyes, margin rotinded 

 over to front. Front broad, nearly as wide at antennae as its 

 length, broader at apex than at base of clypeus, clypeus narrowing 

 slightly at apex, apex broadly rounded, lores ovoidal, not reaching 

 border of genae, pronotum semicircular in front, slightly concave 

 behind, elytra with conspicuous nervures, one cross vein between 

 the fork of the radial and ulnar veins, apical cells well developed, 

 very narrow appendix. 



Color. Greenish olivaceous to brownish. The vertex, anterior 

 border of pronotum, scutellum, and costal border of elytra mostly 

 greenish yellow, posterior portion of pronotum and elytra except 

 costal margin a rather translucent greenish gray, the elytra 

 in some specimens deeply infuscated. Front yellowish gray with 

 faint arcs, the sutural lines infuscated, those between the apical 

 portion of the lores and clypeus sometimes broadening slightly to 

 a fairly distinct spot, thorax and end of abdomen below mostly 

 black, yellow margins, the legs greenish with fuscous points and 

 tarsal claws, all the colors more intense in the male. 



Genitalia. Last ventral segment of female moderately long, 

 polished, truncate at apex, slightly, produced at lateral angles and 

 faintly notched at middle, py gofers extending almost to tip of 

 ovipositor, scantily clothed with short setae. Male, last ventral 

 segment with yellowish border, the valve short, obtuse, angulate 

 behind, blackish, the plates angulate narrowing gradually to an 

 obtusely rounded tip. 



Three .specimens of this species collected by Mr E. P. Van Duzee 

 at Lake Placid in the Adirondacks. I have also a specimen from 

 Sault Ste. Marie collected by Mr H. M. Parish. 



While very distant from the locality where this species was 

 originally described the fact of its occurrence in .the mountain 

 region and the intermediate locality of Sault Ste. Marie indicates 

 that it has a rather wide distribution in boreal regions. It was 

 thought to be undescribed but there seems little doubt that it 

 belongs to this species.
