several fairly coarse teeth or serrations. Anterior tibiae somewhat 

 similar to those described in T. politus. The apical segments of the 

 abdomen rather hirsute, the subgenital plate with its apex widely 

 emarginate, and the apex of the preceding segment entire, nearly 

 truncate. 



Length of body, 5.1 mm.; to tip of wings, 7 mm. 



Habitat. — The type of this species comes from Puerto Suarez, 

 Bolivia, where it was taken by J. Steinbach at an elevation of 150 

 meters above sea-level. There are also two other specimens at hand. 

 One of these latter comes from Santarem and the other from Benevides, 

 Brazil (July). These latter specimens were presumably taken by H. 

 H. Smith. All three belong to the Carnegie Museum. 



12. Tridactylus politus sp. nov. 



Small, slender, and of a pale ground-color with prominent markings 

 of fuscous on the head, pronotum, tegmina, and middle and hind 

 femora, and with a highly polished or glabrous surface. 



Head of medium size, the front short, the clypeus narrowed anter- 

 iorly and with its apex roundly emarginate. Anterior portion of the 

 pronotum showing a well-defined, slender, transverse, impressed line. 

 Wings caudate, slender, extending fully one-fourth of their length 

 beyond the tips of the hind femora and abdomen. Next to the last 

 ventral segment of the abdomen of the male rather large, the outer 

 or apical portion thickened, brunneous, and with the apex broadly 

 rounded, entire; the last segment semimembranous, gently tapering, 

 its apex truncate. Anterior tibiae short, quadridentate, the internal 

 face widely channeled. 



Length of body, cf, 4-85 mm.; to tip of wings, 6.6 mm. 



Habitat. — " Morro do Para, on Rio San Francisco, Bahia, Brazil.

 the same locality-label and date are deposited in the Carnegie Museum.
