S0.1215. REVISION OF rilE GENUS TRIMEROTROPIS— MCNEILL. 423 



Ired or yellow flushed with red, with an inconspicuous basal yellow 

 cloud, oontinod to the outer side. 



Length of body, male 21 to 25 mm., female 25 to 27 nun.; liMioth 

 of tegmina, male 24 to 25 mm., female 27i to 30 mm.; length of pos- 

 terior femora, male 11 to 12^ mm., female 13 to 14 nun. 



TRIMEROTROPIS CAMPESTRIS Bruner, Manuscript. 



This species is pro])ably nothing more than a variety' of TrimeTO- 

 trojjls pallid Ipennis^ from which it apparently does not difter except 

 in the structure and color of the posterior tibia?; the marked infus- 

 cation of the top of the head and the prozone being repeated with 

 almost, if not quite, as much distinctness as in that species. The pos- 

 terior femoi*a are unusually slender, with the black bands of the inner 

 face small, but all the markings obscured by a fuliginous suffusion 

 which extends upon the lower sulcus. I have two females from the 

 Bruner collection, both marked "type," which differ considerabh' in 

 size, markings of the tegmina, and the width of the fuscous band. l)ut 

 they agree in structural points and especially in the hind femora. The 

 smaller one has the fuscous points very imperfectly gathered into 

 bands. 



Length of body, female, 24 to 2S mm. ; length of tegmina, 25 to 2T 

 mm. ; length of posterior femora, 11 to 14 mm. 



One male and one female, Pine Bluffs, Wyoming; Bruner collection. 



TRIMEROTROPIS BRUNERI, new species. 



Hadrotett'ix gracilis Bruner manuscript. 



Reddish brown, not strongly punctate with fuscous Ijut very con- 

 spicuously banded on the tegmina and posterior femora; head, and less 

 commonly the lateral lobes of the pronotum in front of the principal 

 sulcus, pallid; pronotum with a longitudinal whitish stripe on the 

 upper part of the lateral lobes, extending from the middle sulcus to 

 the front margin; below this, near the middle of the lobes, a second but 

 smaller quadrate spot of a similar color. Scutellum of the vertex 

 somewhat (male) or not (female) longer than wide (if the very slightl}'' 

 impressed median faveolse are included as a part of the scutellum, the 

 proportion of length to breadth will be considerably increased); 

 median carina present and more or less distinct; eyes decidedly shorter 

 than the genal grooves even in the male. Pronotum with the median 

 carina very low, not bilobate on the prozone; anterior margin decid- 

 edly angulate; metazone about twice as long as the prozone, its disk 

 evenly and \^\ finely granulate; process of the metazone decidedly 

 acute-angled, with the nnirgins straight and the tip a little rounded. 

 Tegmina, more especially in the male, narrowed considerably and 

 regularly from the basal l)and to the apex; basal and median bands 

 very distinct and solid, with the base rouged without fuscous puncta-
