8 Studies in Kansas Insects. 



never twice as long as the infraocular portion of the genae, the inter- 

 space between them very rarely broad, generally narrow; the fastigium 

 is more or less declivent, never greatly produced in the axis of the body, 

 apically entire and with no transverse ruga, passing insensibly and with 

 obtuse arcuation into the frontal costa; the latter is hardly rounded as 

 seen from the side, percurrent or subpercurrent, generally sulcate, the 

 sulcation ordinarily confined to the lower portion ; without foveolae, the 

 tempora small, obliquely declivent, confused with the front; the superior 

 ocelli more distant than the antennal scrobes; the lateral carina? of the 

 face nearly equidistant from the lateral margins of the frontal costa, 

 but slightly divergent inferiorly. The dorsum of the pronotum is nearly 

 plane and without a crest, generally with no distinct lateral carinae, but 

 at most with rounded shoulders or feeble rugae to represent them, but 

 often passing insensibly in the lateral lobes; the principal sulcus is con- 

 tinuous; the prozona is generally smooth or obsoletely punctate, never 

 tuberculate, its sulci generally feebly impressed, often mesially inter- 

 rupted or subinterrupted, the posterior sulcus often distinctly divergent 

 laterally from the principal sulcus; the metazona is generally shorter 

 than the prozona and lies in the same or nearly In the same plane with 

 it, almost always densely punctate ; the lateral lobes are truncate or sub- 

 truncate posteriorly, with no humeral sinus or only a feeble one, the 

 posterior lower angle distinctly obtuse. The prosternum is armed with 

 a spine, which is usually rather prominent and conical, sometimes trun- 

 cate, never sinuate, generally vertical on the posterior face, nearly or 

 quite as high as the anterior coxae, the posterior portion of the proster- 

 num not or but slightly tumescent; the mesosternal lobes are quadrate 

 or transverse, separated more or less widely, the apical inner angle rec- 

 tangulate or obtusangulate, generally rounded (often obtusely) , the 

 inner margins generally rounded, often posteriorly divergent; the meta- 

 sternal lobes are contiguous or not very distant, excepting sometimes in 

 the female, and then rarely as distant or even nearly as distant as the 

 metasternal lobes. The tegmina are frequently abbreviate or even 

 wanting; when fully developed they taper gently almost throughout 

 and are rather remotely reticulate at least in their apical half, the cells 

 of the postradial area wholly or partially biseriate in arrangement on 

 either side of an intercalary vein; the wings are almost always clear 

 and uniform, never definitely pictured, the veins never scalariform, the 

 areolae quadrate or longer than broad. All the tarsi are furnished with 

 an arolium, the front legs are less distantly separated than the hind 

 pair, the fore tarsi are of moderate length, first joint short or rather 

 short; the hind femora are distinctly incrassate basally, generally sur- 

 pass the abdomen, the upper face generally smooth, the dorsal carina 

 entire, unarmed, not profoundly excised before the geniculation ; the 

 hind tibiae have smooth lateral margins, the spine of the outer and inner 

 series are equal or subequal in length, those of the outer series typically 

 nine or more in number, rarely exceeding fourteen, placed at subequal 

 distances apart and lacking an apical spine next the calcaria; the hind 

 tibiae have the first joint not compressed, equal to or slightly longer than 

 the third, the second much shorter, generally a half shorter, than the 

 first, as seen from above. The second dorsal segment of the abdomen
