Bruner: Tropical American Tettigonoidea. 359 



97. Nannotettix steinbachi sp. nov. 



Most closely related to guentheri Brunncr, but differing from it in 

 the somewhat larger size, the absence of the black lines from the sides 

 of the pronotum, etc. 



General color brunneo-testaceous, with darker markings on the 

 sides of the abdomen, and a pale yellowish line on the sides of the 

 occiput and along the pronotal carina?. Antenna? unicolorous, fer- 

 ruginous. Face of female dirty greenish gray, of male grayish brown, 

 sides of front ^-ellow-bordered in female, orange-bordered in male. 

 Pronotum rugulose both above and at the sides, the transverse sulci 

 deeply impressed. Tegmina brown with testaceous nervures, reaching 

 the hind border of the first abdominal segment in both sexes, their 

 apex broadly rounded. Abdomen at sides and dorsally wood-brown 

 varied with piceous, most strongly so in the male, where the sides are 

 almost entirely of this color, while in the female the posterior margins 

 of the segments alone are thus marked. Immediately above this 

 dusky niaculation there is a well-marked longitudinal testaceous line 

 giving to the insect a vittate appearance. Beneath testaceous, the 

 femora ferruginous, a little paler at their base, darker apically. An- 

 terior and middle femora below three- to four-spined, hind femora 

 about seven-spined. Last ventral segment of the abdomen of the 

 male somewhat attenuated, the apex roundly emarginate, the styles 

 large, about five times as long as broad, the apex blunt. Cerci 

 pallid in both sexes, in the male very robust, bullate, with the apex: 

 greatly constricted, bent inwardly, and provided with an anteriorly 

 directed spine. Ovipositor normal, the apical half rubro-piceous.. 

 Subgenital plate of female triangular, the apex triangulately emargi- 

 nate.
