times as wide as long, and obtusely conical and broadly rounding with 

 front, blunter apically than nhleri. Pronotum about twice as long as 

 vertex, lateral margins short, posterior margin distinctly concave, disc 

 transversely wrinkled. Elytra broad, exceeding abdomen, broadly round- 

 ing and slightly flaring apically. 



Color: Shining black; vertex with ocelli, two basal spots and some- 

 times an apical spot, yellow. Face with a few yellow arcs on front. 

 Front and middle legs yellow from the apex of the femora. 



Exte7'nal genitalia: Female, last ventral segment slightly longer than 

 preceding, posterior margin broadly and shallowly emarginate, slightly 

 produced medially, lateral angles obtuse; pygofers broad, nearly or quite 

 equalling ovipositor, sparsely spined on distal half. Male, valve broad, 

 triangular, very obtuse apically, nearly or quite as long as last ventral 

 segment; plates over twice the length of the valve, roundingly triangular 

 to blunt apices, margins and tips spiny, equalling the apically rounding 

 pygofers. 



Distribution: Seemingly found only in the eastern portion of 

 the state as shown by its occurrence in Douglas, Pottawatomie, 

 Linn and Chautauqua counties. 



Hosts: A grass species.

Form: Rather long and slender, especially the males. Length, 3.5 

 to 4.5 mm. Vertex about one-fourth longer on middle than near the eyes, 

 twice as wide as long, disc sloping and broadly rounded with front, apex 

 obtusely angled. Pronotum nearly or fully twice the length of the ver- 

 tex, lateral margins short, posterior margin slightly emarginate. Elytra 

 long, much exceeding the abdomen, somewhat flaring. 



Color: Vertex, pronotum and scutellum dirty or greenish-yellow. Ver- 

 tex with two curved marginal lines, a median transverse band and pos- 

 teriorly a band or a row of two or four spots, brown. Pronotum irregu- 

 larly marked with brown spots, often a row of them near and parallel to 

 the anterior margin. Scutellum pale or marked with brown spots, basal 

 angles often marked with orange-brown. Elytra greenish-brown, ner- 

 vures light and narrowly fuscous-margined. Face light, with sutures and 

 arcs black. Basal two-thirds of femora black, apices and tibiae yellow. 



{External genitalia: Female, last ventral segment slightly longer than 

 the preceding, posterior margin emarginate between the produced lateral
