NO. 1215. liEVISTOX F THE C EX US TR TMKRO TROPIS—McNEILL. 413 



TRIMEROTROPIS COQUILLETTI, new species. 



Size medium. Color dark brown, nearly plain, since the punctations 

 are so small and dense as to serve merely to darken the g-eneral color 

 without being- themselves conspicuous. 



Scutellum of the vertex with a distinct median carina; median 

 f oveola^ deeply and lateral f oveola? ver}" lightly impri^ssed. Pronotum 

 with the prozone elevated somewhat and the median carina cristate 

 and slightly bilobate; lateral carina^ obsolete on the metazone, visil^le 

 on the front margin of the prozone^; metazone a little less than twice 

 as long as the prozone and rugulose with a few scattered larger gran- 

 ulations; margins of the obtuse-angulate process straight, the tip 

 rounded. Tegmiua very long, with the entire middle field unspotted 

 except narrowly along the margins and h3^aline on the outer half, y&X- 

 low on the inner; anterior field infuscated by the presence of numer- 

 ous maculiij on the basal third beyond with a single not ver}' regular 

 series of fuscous spots of varying sizes extending along and on either 

 side of the principal veins; posterior field thickly maculate with fus- 

 cous points at the base bcA^ond infuscated and impunctate; last branch 

 of the radial sector distant from the fork almost half the length of 

 the sector; intercalary vein separated distally from the median b}^ its 

 own width; area of the cubital forks hyaline at the base for half its 

 length without cross veins, beyond with a few cross veins. Wings 

 very long, distinctly more than twice as long as wide, with the apex 

 greatly attenuated, so that the posterior margin is subparallel with the 

 anterior. Disk light yellow, with a narrow distinct fuscous band 

 extending along the posterior margin nearly to the anal angle, with a 

 spur reaching half way toward the base; apex hyaline. Posterior 

 femora with the disk of the inner face black with two white bands, 

 lower sulcus black with one; outer face with one pale preapical pre- 

 ceded by a fuscous band. 



Posterior tibiae obscure 3'ellow. Length of body (female), 26 mm.; 

 length of tegmina, 30 mm. ; length of posterior femora, 14 mm. 



Ty2)e. — Cat. No. 6371,U.S.N.M. ; one female, San Bernardino County, 

 California. Coquillett collection. 



The species is named in honor of the distinguished entomologist 

 Dr. D. W. Coquillett. 



CINCTA group. 



In the pattern of the wings and in the flatness of the disk of the 

 pronotum transitional to Cmiozoa. 



Frontal costa sulcate for a short distance above the ocellus; scutel- 

 lum of the vertex moderately sulcate, about as wide as long (female), 

 or considerably longer (male) because of the inclusion of the median
