the prozuiK- and nmcli depressed at the posterior border; nietazone, 

 with the disk, moderately smooth, with a few krg-er g-ranulatioiis, 

 which tend to run into lines; the process strongly obtuse anguhite, 

 with tlie borders straight and the tip rounded. Tegmina narrow, 

 long, and very conspicuousl}^ banded, as in bright-colored specimens 

 of Trimerotropix rliicHlata. Wings very similar to that species, with 

 the disk pale citron, instead of greenish yellow. Posterior femora 

 distinctly or strongly banded externally, with the lower surface black 

 with a single subapical light band. Posterior tibite obscure yellow, 

 with an inconspicuous light sub])asal annulus. 



Length of body, male, 19 mm., female, 25^ mm. : length of tegmina, 

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

 mm., female, 13^ mm. 



San Jose del Cabo, Mexico. 



One male and one female from the collection of the California 

 Academ}' of Sciences. 



The species is easily distinguished from Trimerotropis mneuhitd l)y 

 its small size and very short and l)road pronotum. 



TRIMEROTROPIS FRATERCULA, new species. 



Size small, color light reddish brown, head livid, rest of the body 

 and limbs thickly but not very conspicuouslv maculate with fuscous, 

 tegmina conspicuously maculate. Frontal costa decidedly narrowed 

 aboA-e and below the ocellus, the lateral carinse fading before reaching 

 the clypeus; scutelhun moderately broad and not narrower propor- 

 tionally in the male than in the female; median carina scarcely distinct. 

 Pronotum with the median carina scarcely cristate even on the pro- 

 zone, very distinct on the metazone, seen from the side not bilobate; 

 metazone nearly twice as long as the prozone; metazone with the disk 

 finely granulate, man}^ of the granulations exhibiting a tendency to 

 run into lines; metazonal process acute-angled with the sides barely 

 arcuate and the tip sharp. Tegmina broad with the usual bands dis- 

 tinct but more obviously composed of aggregations of small spots than 

 usual in this group; area of the cubital forks tilled with several series 

 of polygonal cells even in the male; last branch of the radial sector 

 nearer the fork than usual in the group, being distinct little more 

 than one- fourth (female) or one-third (male) the length of the sector. 

 Wings broad, being about one and three-fifths times as long as broad; 

 disk light yellow with the fuscous band moderately })road and dis- 

 tinct but interrupted narrowly behind the spur, continued along the 

 posterior margin decidedly less than halfway to the anal angle, with 

 the spur long, extending rather more than halfway to the base; apical 

 portion hyaline without fuscous spots. Posterior femora banded more 

 or less distinctly exteriorly, lower sulcus black with one subapical light 

 band. Posterior tibia? obscure vellow, faintlv clouded wn'th l)rown
