NO. 1215. EE VISION OF THE GENUS TRIMEROTROPIS—McNEILL. 43 5 



moderately broad, bcin^- ahoiit onc-fit'lh of the lenoth of the wino-, 

 continued on the po.stei'ior niaro-in nuich k\ss than halfway to the 

 anal angle; spur long, extending more than halfway to the l)a.se; apex 

 hyaline without fuscous cells. Posterior femora unusualh' long and 

 slender, with the disk of the inner face mostly light colored, a stripe 

 on the l)asal half, a l)and in the middle of the apical half, and the knee 

 blackish. Posterior tibife obscure whitish, unhanded. 



Length of body, male, 19^ mm. ; length of tegmina. 22|^ mm. ; length 

 of posterior femora. 12 mm. One male, Los Angeles, California. 

 Bruner collection. 



The species was based upon a single male froin Los Angeles. The 

 only specimen I haye seen is a male from this locality, marked tj^pe, 

 but it differs quite remarkably from the measurements given hy 

 Bruner and is therefore probably not the specimen upon which the 

 species was originally leased. 



VINCULATA group. 



Frontal costa distinctl}'^ sulcate, with the carina distinct to the central 

 foveolse, but rarely reaching the clypeus; aboyethe ocellus usually less 

 deeply sulcate than below, but neyer full and rounded; scutellum of 

 the yertex moderately or deeply sulcate, only rarely not plainly longer 

 than l)road, with the median carina usualh^ distinct; median and lateral 

 fo^•eohe distinct; eyes neyer longer than the genal grooye CA'en in the 

 males, plainly shorter in the females. Pronotum with the median 

 carina barely cristate on the prozone, a raised line on metazone; the 

 latter from one and thi-ee-fourths to twice as long as the former; lat- 

 eral lobes without a tooth. Tegmina distinctly 1)anded. with the bands 

 at the ends of the first and second quarters plainly darker (except in 

 deeply infuscated specimens), and though generally irregular and 

 variable in shape and size, not a mere aggregation of annular spots, 

 but solid or semisolid; spots proximal to the base, for the most part 

 smaller than those on the apical third and few of them annular; light 

 areas beyond the l)asal and median liands nearly or quite free from 

 fuscous spots, the proximal one generally somewhat V-shaped and 

 wider on the anterior margin: last branch of the radial sector distant 

 from the fork about a third (female) generally more than a third (male) 

 of the length of the sector; median and cubital forks never fused, but 

 generally connected by a short cross vein; intercalary vein in its apical 

 half separated from the median b}' scarcely more than its ow^n width 

 even in the females; wings yellow or greenish yellow at the base, with 

 a distinct fuscous l)and; apex hyaline, rarelj^ with any fuscous spots 

 near the apex; second diyiding vein joining the second anal vein much 

 behind the middle. Posterior femora with the disk of the inner face 

 black with two light l)ands on the apical half. Posterior tibi.'v obscure 

 yellow or brown.
