prominent as in the last, and the median carina more distinct, espe- 

 cially in the posterior part of the sciitellum and on the occiput; antennje 

 distinctly attenuate at the tip. Pronotum with the disk of the meta- 

 zone supplied with rather numerous linear granulations; process of the 

 metazone decidedly obtuse angulate, with the margins straight and 

 the tip sharp. Tegmina long and slender, entirely infuscated, or at 

 least fuliginous, except the usual light bands beyond the first and sec- 

 ond quarters, which are well defined and distinct, but scarcely light 

 enough to be conspicuous, the outer much narrower. By transmitted 

 light the usual punctations at the extreme base and on the apical third 

 can be seen; last branch of the radial sector distant from the fork a 

 third or less (male), or a quarter (female). AVings with the disk trans- 

 parent, tinged with olivaceous green, the outer half transparent but 

 faintly fuliginous, with the extreme tip and, in some specimens, clouds 

 in the region of the fuscous band slightl}^ infuscated. Posterior 

 femora with a light preapical band, followed b}^ one and preceded by 

 two rather distinct fuscous bands. Posterior tibiifi steel blue, with a 

 very distinct whitish su])])asal annulus. 



Length of body, male, 22 mm., female, 2S mm.; length of tegmina, 

 male, 28i mm., female. 29 mm.; length of posterior femora, male, 

 12 mm., female, 14 mm. 



Types. — Cat. No. 5372,U.S.N.M. ; two males, Los Angeles County, 

 California; one female, California. 



This form may be but a variety of the last, but its striking!}^ differ- 

 ent coloration and the unusual wings forbid my placing it there. 



TRIMEROTROPIS ALBESCENS, new species. 



Size small, color white, sparsely punctate with black on the prono- 

 tum and conspicuously banded with black on the tegmina and posterior 

 femora. 



Scutellum moderately sulcate, considerably longer than broad, with 

 a very indistinct median carina; median and lateral foveolte well 

 impr(\s.sed; eyes more than equal (male) to the genal groove. Prono- 

 tum with traces of the lateral carinas on the front part of the prozone 

 and metazone, the latter one and a half times as long as the former; 

 disk of the metazone with a very few larger granulation; process 

 rectangular, with the sides straight and the tip sharp. Tegmina, like 

 the body, white, with the basal l)and narrow and nearly solid, the 

 median and third bands narrow and obvioush' made up of maculations, 

 but very conspicuous; beyond the third fuscous band a few groups 

 of fuscous annuli; all the white bands very broad and impunctate, 

 except the basal, with a few dusky points, and an oblique black dash 

 just beyond the edge of the pronotum when the tegmina are closed; 

 last branch of the radial sector distant from the fork more than one 

 third (male) the length of the sector; median and cubital forks not
