TRIMEROTROPIS SALINA Bruner, manuscript. 



Size, modium; color, dark fuscous brown, obscurely nmculatc. 

 Frontal costa considerably constricted above and below the ocellus; 

 scutellum very broad, being very little longer than broad in the female, 

 slightly longer in the male, moderately sulcate, with the median carina 

 scarcely distinct. Pronotum with the median carina scarcely cristate 

 on the prozone and quite distinct on the metazone. The latter is not 

 more than one and three-quarters times as long as the former and has 

 the disk ver}^ evenly and finely granulate, with the process obtuse- 

 angular, the sides straight, and the tip very plainly rounded, Tegmina 

 broad, with the usual markings made little conspicuous by the dark 

 ground color. Wings rather broad, being considerably less than twice 

 as long as broad, with a broad fuscous band occupying not much less 

 than a third the length of the wing, extending on the posterior border 

 much more than halfway to the anal angle. Spur short, reaching less 

 than halfway to the base; apical portion hyaline with a few fuscous 

 spots. Posterior femora without fuscous bands externally; lower 

 sulcus black, with two light bands on the apical half. Posterior tibiae 

 obscure fuscous, with a faint subbasal annulus. 



Length of body, male, 22 mm., female, 29 mm.; length of tegmina. 

 male, 28 nun., female, 30 mm.; length of posterior femora, male, 12 

 12 mm., female, 14i mm. 



One male and one female. Salt Basin, Lincoln, Nebraska, Bruner 

 collection. One male and one female in the collection of Stanford 

 University. 



This species is easily recognized by the broad fuscous band of the 

 wings and the dark hind tibi«. 



TRIMEROTROPIS SIMILIS Scudder. 



Trimerotropis simllis Scudder, Second Kept. U. S. Ent. Com., App. II, 1880, p. 27. 



This species is very closely related to l)oth of the preceding. In 

 the structure of the head and pronotum is not distinguishable from 

 TTimerotropk mncuhda. The wings are precisely similar with the 

 fuscous band, narrow and distinct as in that species, and the apex 

 unspotted, but the general color of the tegmina and Iwdy is quite dis- 

 tinct. The head, body, and liml)s are nearly uniform dark brown. 

 The tegmina have two fairly lighter bands in the usual position, one 

 beyond the basal third and the other just l>eyond the middle of the 

 wing and almost no visible spots anywhere. 



Length of body, male, 22 mm., female, 28 mm.; length of tegmina, 

 male, 24 mm., female, 27 mm.; length of posterior femora, male, 11 

 mm., female, 18 mm. 



Wallula, Washington, Scudder; Washington, Bruner. I have exam- 

 ined two specimens from The Dalies. Oregon, from the Bruner collection.
