This species is most easily recognized, in the female, by the longi- 

 tudinal dorsal length of the epipygium being one and one-half times 

 the length of the eighth tergite; the male has an extremely stout 

 antennal scape which is inserted on a level with the ventral margins 

 of the compound eyes, and the apex exceeds the level of the posterior 

 ocelli. 



Description. — Male: 3.5 mm. Antennae inserted on a level with 

 ventral margins of compound eyes (fig. 7, e), apex of scape exceeding 

 level of vertex, pedicel four times as long as and ring segment one- 

 half length of segment 4, segments 5 and 6 equal to or slightly longer 

 than 4, 7 to 10 progressively longer, so that 10 is one-half longer than 

 4, last three slightly shorter; scrobe cavity shallow, margin entirely 

 without carinae, or with a very indistinct ventral one, a glabrous 

 area just laterodorsad of each antennal base; interantennal pro- 

 jection broad, usually with a minute dorsal carina ; f rons covered by 

 minute reticulations over entire surface, reticulations forming vague, 

 minute parallel carinae on area laterad of scrobe cavity; width of 

 malar space three-fourths or more height of compound eye; com- 

 bined widths of compound eyes one-fifth less than width of inter- 

 ocular space at level of apex of interantennal projection; left man- 

 dible with two blunt teeth, right mandible with three acute teeth; 

 diameter of posterior ocellus slightly less than one-half width of 

 interocellar space.
