Size, small or iiiediuin; color, lioht brown; lioad, pronotuin, and 

 abdomen thickly punctate with minute fuscous spots, teo-mina very 

 conspicuously l)anded. Frontal costa less decidedly sulcate and broader 

 than usual in this group with that part above the ocellus scarcely nar- 

 rowed below the scutellum, which is very moderateh^ sulcate with the 

 median carina indistinct and but little longer than l)road. Pronotum 

 with the median carina strongly cristate with the lobes not very 

 unequal on the prozone, and scarcely perceptible on the metazone 

 which is very nearly twice as long as the prozone; metazone with the 

 disk roughened with larger granulations, some, of which are distinctly 

 linear; process of the metazone a little greater than a rectangle, with 

 the sides very slightly arcuate and the tip sharp. Tegmina very 

 narrow and strongly falcate on the apical third, the usual ))ands similar 

 to those of Trimerofropls mncvlata in structure and position. Wings 

 broader with the costal margin much more strongly arcuate, l)ut with 

 the apex quite as attenuate as in that species; disk greenish yellow, 

 somewhat more transparent than usual and very large, the fuscous 

 band being entirely beyond the center of the wing; fuscous band very 

 narrow, but quite uninterrupted and very distinct, continued on the 

 posterior about halfway to the anal angle, with the spur very long, 

 extending two-thirds of the way to the base; apical portion unusually 

 small, hyaline without spots. Posterior femora rather indistinctly 

 banded on the outer face, the lower sulcus black with two lighter 

 l)ands on the apical half. Posterior femora, obscure yellow with a 

 faint lighter subbasal aniuilus. 



Length of body, female, 27i mm.; length of tegmina, 20 mm.; 

 length of posterior femora, 12 mm. 



One female Carcarana, Argentina, South America, Bruner's collec- 

 tion. The species is known to me only through a single specimiMi. but 

 seems very distinct in the tegmina and wings. 



TRIMEROTROPIS COLLARIS. new species. 



Size small, color clay yellow% head and a])domen plain, pronotum 

 moderately and tegmina always very conspicuously banded and 

 spotted with fuscous. Scutellum narrow% deeply sulcate, with the 

 median carina moderately distinct and elongate, being one and a half 

 (female) or twice (male) as long as wide. Pronotum very short and 

 t)road, the length being equal to (female) or barely greater (male) than 

 the width, with the median carina strongly elevated on the anterior of
