J*. Eyes never as close together as the distance between the hind 

 ocelli, these not touching the eyes ; the temple narrow but distinct ; 

 incision of the eye sometimes subacute but usually broadly rounded at 

 apex ; front with a low tubercle between and slightly above the bases 

 of the antennae ; clypeus slightly or strongly convex, broadly emargi- 

 nate anteriorly. Antennae as long Or longer than the head and thorax 

 united ; scape subglobular ; pedicel about one-third its length ; segments 

 3 to 6 cylindrical or compressed and somewhat widened at their apices, 

 the third always linear, the seventh slightly or strongly widened, some- 

 times more than twice as long as wide ; segments 4 to 7 in one species 

 flat beneath ; club short, not or but slightly exceeding the length of the 

 sixth and seventh segments, ovate, convex above and below or, as in 

 one species, hollowed beneath. 



Humeri entirely rounded or more or less prominent ; parapsidal 

 furrows absent ; angles of propodeum dentate or only sharply carinate. 



Anterior leg not contorted ; surfaces of the segments uniform ; 

 femur and tibia more or less flattened beneath ; tarsus in one species 

 eiliate ; middle femur with its undersurface convex and regular or 

 contorted and concave ; tibia with its undersurface convex and regular 

 or dilated, contorted and concave, but both segments never with uni- 

 form undersurfaces in the same species; middle tibia from two-thirds 

 to four-fifths as long as the tarsus; metatarsus two-thirds to three- 

 quarters as long as the remaining segments together ; fourth segment 

 as broad as long or almost so; hind tibia from .6 to .8 as long as the 

 tarsus ; metatarsus without an apical lobe, approximately equal to the 

 remaining segments united, fourth segment longer than broad. 



Basal abdominal segments considerably contracted above at their 

 bases ; abdomen nnich decurved at apex, the last segment with its apical 

 surface truncate, the truncature margined with 2 superior sharp or 

 obtuse prominences and 2 inferior smaller tubercles placed closer to- 

 gether ; second ventral segment with 2 low tubercles ; process of the 

 third high, posteriorly with an acute tooth directed caudad. 



Squama obtuse without setae beneath or with a small patch of 

 bristles ; sagitta trigonal, the angles carinate ; uncus usually short and 

 blunt but in one species elongate, slender, curved, and acute.
