526 NEW YORK STATE MUSEUM 



Length of female to tip of elytra 5. mm. Length of male to 

 tip of elytra 4.75 mm. 



Vertex subangulate about one and one half times as long at 

 middle as next eye. Front narrowed below antennae, clypeus 

 expanding from middle. Lores large, their borders almost touch- 

 ing margin of cheek. Pronotum broad, posterior border concave. 

 Claval veins not very strongly recurved. Reflexed veins two or 

 three, from anterior half of outer ante-apical cell. 



Color. Grayish tinted with fulvous. Vertex ivory white 

 crossed by a rather obscure brbwnish band. Prothorax with 

 ivory white band between hind border of eyes. Scutellum polished 

 ivory white, except outer angles which are black. Sutural border of 

 clavus with broad circular milky or milky opalescent spots separated 

 by a black bar on the slightly recurved claval vein and with a 

 black spot anteriorly and posteriorly, the latter at the end of the 

 clavus. The remainder of the elytra with fuscous, fulvous and 

 milky white patches of general pattern of i m m i s t u s . 



Genitalia. Last ventral segment of female long, posterior bor- 

 ders, rounded, polished, black on apical portion. Male; valve 

 short, rounded; plates short reaching a little more than half the 

 length of pygofer, obliquely truncate, minutely ciliate. 



This species was beaten from red cedar at Cold Spring Harbor 

 and appears in some minute particulars to differ so distinctly from 

 the varieties of i m m i s t u s that it seems best to give it 

 separate description. While there is little difference in genitalia 

 or general color pattern, there is quite a marked difference in the 

 width of the claval spots, angle of the claval vein, and shape of 

 body as a whole. The two circular opalescent spots formed by 

 the semicircles on each clavous present a quite distinctive picture.

Athysanus venosus n. sp. 



Robust, broad, elytra with very conspicuous pallid veins, apical 

 cells nearly obsolete. Length of female to tip of ovipositor, 5 mm. 



Vertex elongate, one and one third times as long at middle as 

 at eye with a rather evident elevation paralleling the occiputal 

 margin from front border of eye, vertex rounding uniformly on 

 to front, front broad, full, tapering evenly to the apex which is 

 slightly broader near base, clypeus slightly rounded. Pronotum 

 short, about three times as wide as its length at middle, almost 

 lunate in form, the scutellar margin distinctly concave, elytra 

 short reaching base of sixth dorsal segment, subhy aline, veins very 

 conspicuous, a second cross vein between inner fork of the ulna 

 and the radial, five apical cells, four lying next the subtruncate 

 apical margin much reduced, wings about three fourths length 

 of elytra.
