width to about one-fifth the length of the wing, continued upon the 

 posterior l)order much more than halfway to the anal angle. Spur 

 v^ery short, extending less than one-fourth of the way to the base. 

 Posterior femora with the whole inner face reddish, l)ut more or less 

 suffused with fuliginous, so that the three ])lack bands are not easily 

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

 Posterior tibije red with the usual light su])basal cloud.

One male and one female, Sidney, Nebraska. Bruner collection. 



This species is unique among the red-legged Trimerotropis for its 

 plain tegmina. 



PACIFIC A group. 

 TRIMEROTROPIS PACIFICA Bruner. 



Trimerotropis pacijica Bruner, Proc. I'. S. Nat. Mu8., XII, 1890, p. 78. 



Size medium, color light cinereous, with minute fuscous punctations 

 scarcely visible to the naked eye and serving merely to darken the 

 ground color, bands on the tegmina conspicuous. 



Scutellum but little constricted above or below the ocellus, very 

 moderately sulcate with the lateral carina vanishing long before reach- 

 ing the clypeus; scutellum much longer than wide, barely sulcate, with 

 the median carina nearly as distinct as the lateral; eyes scarcely as 

 long as the genal groove even in the male; antennae longer than usual 

 in the genus, slightly flattened and distinctly attenuate at the tip. 

 Pronotum with the anterior margin decidedly angulate; median carina 

 not cristate even on the prozone, on the metazone, a raised line as dis- 

 tinct posteriorly as anteriorly; metazone with the disk smooth oi- 

 very evenly granulate; the process acute-angular with the sides straight 

 and the tip pointed; lateral carinae entirely wanting even on the ante- 

 rior of the pi'ozone; lateral lobes with a minute tooth on the lower pos- 

 terior margin. Tegmina narrow, with the fuscous l)ands solid and 

 contrasting strongly with the very light ground color; the usual 

 annular spots wanting, almost entirely proximate to the l)asal l)and 

 and restricted on the distal third to a series of groups along either 

 margin, the first on the anterior margin being Gonspicuoush' larger; 

 hyaline portion of the tegmina with (juadrate cells, limited ])V a line 

 extending obliquel}" across the tegmina about halfway between the 

 median fork and the last branch of the radius; intercalarv vein in its 

 apical portion very close to the median, being separated from it by 

 not more than its width; area of the cubital forks narrow% t>ut filled 

 with mor(^ than one series of polygonal cells. Wings narrow with the 

 apex attenuated, twice as long as l)r()ad; disk dilute yellow, with the 

 fuscous l»and interrupted below the spur, but otherwise distinct and
