Studies in Kansas Insects. 



The females, of which we have two, do not differ materially from the 

 males. The tegminal bars are perhaps not quite so solid, a little more 

 loosely put together, and aside from this they agree in all the essential 

 details with the males. 



Measurements in Millimeters. 



Body. Tegmina. Post, femora. 



Females 42.5-39.2 38.0-24.0 20.5-18.5 



Males 35.0-29. 36.0-20.0 19.5-15.2 



Distribution. 



T rimer otropis agrestis McN. 

 Proc. U. S. Nat. Mus., vol. 23, p. 433. 



Pale reddish brown, with the face and sides of the head whitish, plain, 

 with a few scattered spots on the tegmina, not showing any trace of the 

 usual arrangement into three bands. 



Front plainly sulcate above as well as below the ocellus; scutellum 

 strongly sulcate, with the merest trace ,of a median carina, broad, al- 

 most equaling the long diameter of the eye in the female; eyes plainly 

 (male) or much (female) shorter than genal groove. Pronotum with 

 the median carina more than usually distinct on the metazona, slightly 

 cristate and plainly bilobate on the prozone; median carina? barely visible 

 on the front part of both metazone and prozone; metazone nearly twice 

 as long as the prozone, with the disk finely granulate and the process 

 decidedly obtuse-angulate ; lateral lobes with a large tooth, which causes 

 the posterior lower angle to appear to be drawn downward. Tegmina 

 entirely plain except for a few scattered spots, without a trace of the 

 usual bands. Wings moderately broad, with a distinct and wide fuscous 

 band, which is equal in width to about one-fifth the length of the wing, 

 continued upon the posterior border much more than half way to the anal 

 angle. Spur very short, extending less than one-fourth of the way to the 

 base. Posterior femora with the whole inner face reddish, but more or 

 less suffused with fuliginous, so that the three black bands are not easily 

 distinguished ; outer face plain, with a narrow light subapical band. 

 Posterior tibiae red with the usual light subbasal cloud. 



Length of body,* male 22 mm., female, 27 mm. ; length of tegmina, 

 male 23 mm., female 28 mm.; length of posterior femora, male 11 mm., 

 female 13.5 mm.
