brown. Brachypterous females are uniformly orange-yellow, except for 

 dark eyes and ocelli. Brachypterous males of same color as brachypterous 

 females, or dark, with vertex, pronotum and scutellum a yellowish-brown, 

 elytra smoky-brown, and abdomen brownish-black. 



External genitalia: Female, last ventral se^jment short, broad, slightly 

 emarginate posteriorly and with a small, median, bilobed process; py- 

 gofers broad, slightly exceeded by black ovipositor, bristled apically. 

 Male, last ventral segment about length of preceding, emarginate pos- 

 teriorly; valve small, rounded posteriorly; plates broad basally, con- 

 cavely narrowed to attenuate and acute tips which exceed the short, 

 bristly pygofers. 



Distribution: Though not yet reported from Kansas, this 

 species surely occurs in the state. 



Hosts: Osborn and Ball report it from Spo?-o&o^ws. De Long 

 took it in great numbers on Aristida gracilis. 



Lormtura noctivaga Ball.

Form: Large and robust. Length, 4 to 5.5 mm. Vertex at least one- 

 fourth wider than long, sloping and broadly rounding with front, apex 

 obtusely angled. Pronotum short, scarcely as long as vertex, anterior 

 margin broadly convex, lateral margins long, humeral margins long, 

 scarcely angled with the somewhat emarginate posterior margin. Elytra 

 short and broad, obliquely truncate, covering first two abdominal seg- 

 ments, venation obscure and reticulate. 



Color: Creamy-yellow; vertex with four large marginal black spots, 

 the outer the larger, with a faint transverse band behind the latter, back 

 of which may be irregular brownish spots, and with a dark median line. 

 Pronotum vdth five light longitudinal lines. Elytra with nervures light, 

 one or two black spots on posterior margin and often one or more be- 

 tween these and the scutellum. Abdomen dark olive with creamy stripes. 



External genitalia: Female, last ventral segment one-third longer 

 than preceding, strongly narrowed posteriorly, lateral angles broadly 

 rounded, posterior margin twice notched, with a small median lobe; 

 pygofers long and narrow, narrowed basally, sparsely spined, exceeded 

 by the very long ovipositor. Male, last ventral segment longer than the 

 preceding, posterior margin concave; valve very small, rounded pos- 

 teriorly; plates broad and long, spiny margins tapering to acute tips 

 which are slightly exceeded by the short, sparsely spined pygofers. 



Distribution: This species has not yet been reported from 

 Kansas but should occur in the northeastern portion of the 

 state. 



Hosts: Unknown.
