foveolfe; eyes about equal (male) or a very little less (female) than the 

 ^enal groove; antemue slightly exceeding (male) the posterior femora. 

 Pronotum with the disk flat and the shoulders well marked even on 

 the prozone, and lateral carina? present on the anterior of the meta- 

 zone and in front of the first sulcus, broken or entirely wanting 

 between, and on the posterior part of the prozone; median carina 

 moderately elevated and bilobate on the prozone with the anterior 

 lobe much greater than the posterior; process of the metazone obtuse 

 angulate with the sides straight and the tip sharp; lateral lobes with 

 the posterior angle rounded. Tegraina with the median and basal 

 dark bands solid and well defined, extending across the anterior and 

 middle fields, the former sometimes faintly visible on the posterior 

 field also; the light bands just beyond the dark ones about equal to 

 each other and to the dark bands; apical third with fuscous annuli in 

 somewhat regular series along either margin with a few scattered ones 

 on the area between which has the principal and the adjoining vein- 

 lets darkened; extreme base punctate wdth fuscous; posterior field 

 impunctate or most obscurely punctate; area of the cubital forks 

 broad and filled with several series of poh^gonal cells in the female, 

 in the male narrower, but the cells are in about two series; median 

 and cubital forks not fused, free or united by a cross vein; inter- 

 calary vein separated from the median toward its tip by a distance 

 several times (female) or at least once (male) its own width. Wings 

 narrow, with the disk pale-greenish yellow, with the fuscous band 

 narrow and ill-defined on the outside, shading off into fuliginous but 

 disappearing for the most part in the subapical area, the tip again 

 becoming infuscated or remaining clear, continued on the exterior 

 margin less than half way to the anal angle. Spur long, extending 

 more than half wav to the base. Posterior femora with the disk of 

 the inner side black with two light bands on the apical half; lower 

 sulcus pale or more or less suffused with fuscous, with one black baud 

 before the pale preapical band.

Probabl}" none of the other references to (Edipoda^ 2L'sfoJ)re(jm<i^ or 

 Ti'uiitrotrojjU clncta belong here. Thomas probably confused three, 

 if not four, species under this name, one Mestobregma and three Tri- 

 riierotrojns. See Tnineroti'02>l>< chicvlaia, and sa,mtUh. Size medium, 

 color dark and nearly plain except for two distinct, narrow, black bands 

 w^hich extend across the face, one just above and the other just below 

 the insertion of the antennte. These bands unite at the eye and extend 

 as a narrow stripe from the posterior margin of the eye, across the
