NO. 1215. RE VISION OF THE GENUS TRIMEROTROPIS—McNEILL. 433 



not more than one-third of the way to the base. Posterioi' tViiiora 

 with the disk of the inner face black, with tAvo yellow bands on tin; 

 apical half; lower sulcus yellow, with one subapical black hand; outer 

 face plain, with a single black transverse subapical band. 



Length of body, male 21 mm., female 29 nun.; length of tegmina, 

 male 18 mm. , female 28 mm. ; length of posterior femora, male 11^ mm. , 

 female 12^ mm. 



One male and one female, Salt Lake Valley, Utah, Sept(>mber; 

 Hruner collection. 



This and the following species may be but varieties of an exceedingly 

 variable species. This doubt can only be cleared up hy more speci- 

 mens from intermediate points. 



TRIMEROTROPIS MONTANA Brunei, manuscript. 



This species differs from both the preceding species, to which it is 

 closely allied, in the following particulars: 



Scutellum with the median carina nearly as distinct as the lateral. 

 Pronotum with the metazone scarcely more than one and a half times 

 as long as wide; process of the metazone strongly obtuse angulate; 

 tooth of the lateral lobes minute. Tegmina about as in Trimerotropis 

 ealifornicu. Wing about as in that species, with the band equally 

 narrow, but the spur much shorter, exending not more than a fourth 

 of the way to the base. Posterior femora with the inner face ver3^ 

 similar to Trmierotropii< cal/fornlca and the outer like those of Trlmtr- 

 oti'oph strenua. 



Length of the body, male 11) mm. ; length of the tegmina, 22 mm. ; 

 length of posterior femora, 9^ mm. 



One male, Boise City, Idaho; Bruncr collection. 



TRIMEROTROPIS AGRESTIS, new species. 



Pale reddish })rown, Avith 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. 



Frontal costa plainly sculcate a))ove as well as below the ocellus; 

 scutellum strongly sulcate, with the merest trace of a median carina, 

 l)road. almost equaling the long diameter of the eye in the female; eyes 

 plainly (male) or much (f(Mnale) shorter than the genal groove. Pro- 

 notum with the median carina more than usually distinct on the meta- 

 zone, slightly cristate and ])hiinly bilobate on the prozone; median 

 carina barely visi])le 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 o))tuse-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, Avithout a trace of the usual bands. Wings moder- 

 ately broad, with a distinct and wide fuscous band, which is equj^l in
