N0.1215. REVISION OF THE GENUS TRIMEEOTROPIS— MCNEILL. 405 



TRIMEROTROPIS HYALINA, new species. 



Robust, pale testaceous, almost plain, with a few scattered spots in 

 the middle field of the tegmina occupying the usual position of the 

 fuscous bands; anterior and posterior fields plain except for i^xceed- 

 ingh" faint spots near the base. 



Scutellum of the vertex moderately deep, with faint median carina, 

 as wide as the short diameter of the eye which is considerably shoi'ter 

 than the genal groove. Pronotum with the prozone ele^'ated, median 

 carina high and strongly bilobed; metazone one and a half times as 

 long as the prozone, with the disk smooth and the process strongh' 

 obtuse angulate, its sides straight and tip rounded; lateral carinas 

 obsolete, except upon the front of the metazone and prozone; lateral 

 lo])es with a strong tooth on the posterior part of the lower border. 

 AVings entirely transparent and faintly tinged with yellow; fuscous 

 band entirely wanting, and none of the veins orveinlets are inf uscated 

 except at the extreme tip of the wing. Posterior femora with the 

 disk of the inner face pale, with scarcely a trace of fuscous band, 

 lower sulcus pale, outer face testaceous, obscurely fasciate. Posterior 

 tibite obscure yellow. 



Length of body,, female, 30 mm,; length of tegmina, 3(» mm.; length 

 of posterior femora, 18 mm. 



7///>.^— Cat. No. 5370, U.S.N.M.; one female, California. Deter- 

 mined b}" Uhler as TrimeTotropw 2)^<iudofmciata^ to wdiich it is not 

 very closely related. In size, general proportions, and color (except 

 for the very different tegmina and wings) it resembles Coiiozoa, to 

 which it is much more closely related than Trimerotropls cincta and 

 Juliana are. 



TEXANA group. 



Size medium, color dark gray varied with yellow or white, with 

 ])road light stripes (sometimes indistinct but alwa3's traceable) extend- 

 ing from the eyes along the edge of the disk to the posterior border 

 of the pronotum, no definite bands on the tegmina, but some indication 

 of these in their usual position; veins in the apical portion inf uscated 

 and generally bordered with fuscous which extends out on the cross 

 veins. Head consideral)ly or uuich elevated. Frontal costa sulcate 

 above the ocellus as well as below with the carina? continuous with 

 those of the vertex; scutellum of the vertex deeply sulcate, somewhat 

 (female) or considerably (male) longer than broad, the length being 

 increased by the inclusion of the median foveoUe which are well 

 impressed; lateral foveol* equally distinct; antennae in the male about 

 eiiualing the posterior femora. Pronotum with the disk fiattened and 

 lateral carina; absent at least between the sulci; median carina^ cristate 

 at least on the prozone; metazone with its disk smooth; lateral lobes
