subquadrate, the sides rounded, the margin in front broadly trans- 

 verse, the occipital margin broadly slightly concave; as seen from 

 in front broader than long, the curvature depressed above, strong on 

 the sides dorsad, the cheeks arcuately converging toward the mouth ; 

 as seen from the side the facial outline is about straight and twic? as 

 long as the dorsal side, which is convex, the planes meeting in an 

 obtuse angle, the occipital margin slightly bulging. Occiput moder- 

 ately concave; eyes much smaller than in the female but similar in 

 shape; fronto vertex a little broader than long, its occipital margin 

 rounded off; ocelli in a large, distinctly obtuse angle, the posterior 

 pair remote from the occipital border and their own diameter from 

 the eye margins, the anterior ocellus placed a little in front of the 

 center of the f ronto vertex ; cheeks wide and about as long as the 

 width of the eyes, the genal suture distinct. Face moderately con- 

 vex from side to side, with a very slightly elevated narrow ridge 

 medially from the level of the antennal sockets nearly to the oral 

 margin, a depression below antennae also present in some specimens, 

 due to shrinkage ; antennal sockets situated moderately far apart at 

 the middle of the head, distinctly above the ocular line and hardly 

 more than their own length from the rounded angulation between the 

 face and frons, about their own length apart and slightly less than 

 their own width from the eye margins; scrobes extremely short, 

 extending obliquely inward and uniting, each about one-half as long 

 as the sockets and together forming a shallow lunate depression 

 slightly emarginated medially above. 



Antenna slender, about three-fourths as long as the body, scape 

 very short and stoutly fusiform yet reaching Avell beyond the scro- 

 bal impression; pedicel only slightly longer than thick, very much 

 shorter than the following joint; flagellum long, slender, increasing 

 very slightly in thickness distad, clothed with numerous uniformly 

 distributed longish semierect setae, the first three funicle joints 

 with a much longer curved seta at apex on the dorsal side; funicle 

 joints all longer than thick, the basal joint cylindrical and by far 

 the longest, about six times as long as thick and as long as the scape, 

 the sixth slightly less than one-half as long as the first and some- 

 what less than twice as long as wide; club oval, entire, pointed at 

 apex, and a little longer than the two preceding joints combined. 



Thorax similar to the female but narrower, the mesoscutum rela- 

 tively longer, scutellum longer than wide, rather acute at apex; ab- 

 domen depressed, ovate, about two-thirds as long as the thorax; 

 wings fully developed and similar to the fully developed wings of 

 the female. 



Sculpture coarser but similar; frontovertex much more reticulate 

 than in the female, or about like the face and with scattered shallow
