Lonatura nebulosa Ball. 



Louatuia nebulona Ball. Can. Ent., xxxii, p. 341, 1900. 

 Lonatura nehidosa Van D., Cat. Hemip. N. A., p. 652, 1917. 



Form: Distinctly smaller than noctivaga. Length, 3 to 3.5 mm. Ver- 

 tex nearly one-third wider than long, sloping, broadly rounding with 

 front, obtuse apically. Pronotum longer than vertex, strongly convex 

 anteriorly, lateral margins short, humeral m.argins distinctly angulate 

 with the slightly emarginate posterior margin. Elytra short, covering 

 all but two segments of abdomen, rounded apically, not reticulate. 



Color: Straw colored; vertex with four large marginal black spots 

 back of which are two brown transverse bands, and a brown spot basally, 

 near each eye. Pronotum with a pair of light brown spots on anterior 

 margin and very faint trace of the five light longitudinal lines. Elytra 

 subhyaline, unspotted. Abdomen with transverse row of fuscous dots 

 on middle of each segment and sometimes with lateral black markings. 

 Pygofers marked with black above. 



External genitalia: P"'emale, last ventral segment shorter than the 

 preceding, composed of two membranes, the inner broadly concave medi- 

 ally, only its lateral rounded angles visible from under the outer basally 

 broad, but apically narrowed membrane which has the posterior margin 

 truncate or slightly produced, and the disc distinctly elevated; pygofers 

 long and somewhat narrow, widest at the middle, very bristly apically 

 and exceeded by the ovipositor. Male, last ventral segment as long as 

 the preceding, valve small, broad but short, rounded posteriorly; plates 

 broad basally, spiny margins concavely narrowed to long acute apices 

 which exceed the very short, very bristly pygofers. 



Distribution: Taken in Cherokee county. 

 Hosts: Unknown. 



Genus Aconura Leth. 



The members of this genus are usually yellowish or grayish 

 species, small and robust. The vertex is broad, obtusely angu- 

 late, transversely depressed and rounding to the front. The 

 pronotum is short, usually shorter than vertex and with pos- 

 terior portion transversely wrinkled. There are some macrop- 

 terous forms, but usually the elytra are very short, and with 

 weak venation. The ovipositor is very long, and the male geni- 

 talia are characteristic due to the abnormally large, chitinous 

 styles and oedagus. Many males also possess a very large 

 dorsal spine at the tip of the hind tibiae which seems to vary 

 for the different species. 



Several undetermined species belonging to this genus have 

 been taken in Kansas, but at present we have been able to 

 make sure of only two species.
