stout, longer than broad, joint 2 half as long as 1, about quadrate, 

 joint 3 half again as long as 2, slender, joint 4 equal to 2, joint 5 as long 

 as 3 but stouter toward apex, joints 6 and 7 each a little shorter than 5, 

 joint 8 equal to 4, joint 9 about as long as 3, a little longer than broad, 

 joint 10 quadrate, joint 11 oval, as long as 9 and 10 together. Except 

 for the outer eight joints of the antennae, which are black, the insect 

 is entirely ferruginous. The most distinctive feature is the front 

 tibia, which is feebly undulate and distally expanded on its inner face 

 into a broadly triangular flange. Middle tibia straight, hind tibia 

 very feebly incurved. Length 2.5 mm. 



Type.— -Male, U.S.N.M. No. 55883. 



Type locality. — Cuernos Mountains, Negros, P. I. 



Another specimen, a female, bearing the same data as the type, is 

 very similar to the type except for the tibiae, which are all simple. 

 Its length is 2.75 mm. I designate it the allotype. 



Genus STENOTARSUS Perty 



STENOTARSUS MONROVIUS, new species 



Figure 12, o 



General aspect of S. guineensis Gerstaecker but much, smaller, 

 shorter, and more convex. Ferruginous except apical joint of anten- 

 nae, which is darker but hardly black. Antennae stout, scarcely 

 longer than head and pronotum, joints 2 to 8 beadlike, transverse, joints 

 9 and 10 suddenly broadened, short and transverse, not flattened, joint 

 11 a little shorter than 9 and 10 together, flattened only toward the 

 apex, which is truncate. Pronotum three times as broad as long (at 

 middle), sides evenly rounded but much less so than in guineensis. 

 The elevated margin is very broad and somewhat deflexed in front, 

 narrowed posteriorly to half its anterior width. Hind angles right. 

 Disk of pronotum evenly, not greatly convex, finely and fairly closely 

 punctured. Elytra strongly convex, finely punctured and with widely 

 spaced, coarse, shallow punctures. These larger punctures are espe- 

 cially coarse and numerous along the sides but are discernible to the 

 apex whereas in guineensis they are evanescent behind the middle. 

 Length 3 mm., width 2 mm. 



Type.— Male, U.S.N.M. No. 55884. 



Type locality. — Mount Coffee, Liberia (O. F. Cook). 



Another male specimen identical with the type and bearing the 

 same data is designated paratype and is in the author's collection. 



STENOTARSUS ATRIPENNIS, new species 



Elongate oval, moderately convex, ferruginous with antennae and 

 most of elytra black. Antennae with joint 1 short, subglobose, joints 

 2 and 4 to 7 about as long as broad, joint 3 a little longer than broad,
