Form: Slightly smaller than pwncfaf a. Length, 3.5 to 3.75 mm. Head 

 narrower than pronotum, vertex very slightly longer on middle than next 

 the eye, over three times as wide as long. Pronotum long, anterior mar- 

 gin strongly convex, posterior margin very slightly emarginate. Elytra 

 very long, greatly exceeding abdomen, narrow, overlapping apically. 



Color: Greenish, sometimes tinged with yellow. Elytra greenish 

 basally, becoming whitish apically. 



External geyiitalin: Female, last ventral segment rather long, pos- 

 terior margin truncate; pygofers long and narrow, widest at middle, 

 spiny, equalling ovipositor. Male, valve distinct, nearly semicircular; 

 plates small, margins convexly narrowing to the attenuate tips which are 

 strongly exceeded by the pygofers. . 



Internal male genitalia: Styles produced anteriorly into a wide proc- 

 ess, widest at point of attachment to connective by a rounded inner lobe, 

 preapical lateral incision nearly semicircular, the terminal process rather 

 short, curved, the apex more heavily chitinized and roughened ; con- 

 nective Y-shaped, the arms stout and triangular, separated by a rather 

 narrow incision, the stem longer than the arms, vddened to the truncate 

 apex; oedagus with a broad rectangular dorsally-directed attachment 

 process at the base, the main portion swollen basally and gradually taper- 

 ing to the bread but rather deeply bifid apex, so that it seems to end in 

 two delicate processes. 



Distribution: This species seemingly is found throughout 

 the eastern part of the state as shown by the following map : 



Hosts: No definite host plant seems yet to have been found 

 for this species. It is undoubtedly a grass feeder.
