on all its upper side dense short black bristles, while on its underside 

 are longer hairs ; second joint small, about one-thirds as long as the 

 basal joint, with an apical dorsal process slightly shorter than the joint 

 proper, and with an incomplete apical circlet of black bristles which 

 are short on the upper side but rather longer on the underside ; third 

 joint narrower than the basal joint, with only a small blunt dorsal 

 hump on the basal quarter and usually with a few tiny black bristles 

 there ; style-like portion about three-fourth as long as the basal an- 

 nulation of the third joint, with three basal aimulations about the same 

 in length and about as wide as long, but the apical annulation elongate 

 conical and about twice as long as the preceding one and bearing one 

 or two fine but somewhat conspicuous hairs. Eyes bare, large, convex, 

 in death brownish black on the large facets and deep purplish black 

 on the small facets ; when seen from above the frontal margin about 

 as long as the posterior margin which is nearly straight, and the outer 

 margin evenly convex, the upper angle about ioo° and slightly round- 

 ed ; in profile the frontal margin slightly convex, the facial margin also 

 slightly convex and shortest, and the posterior margin longest and 

 moderately curved posteriorily about the middle, the frontal angle 

 roundish and about iiO°, the upper angle smallest and about 70 , the 

 I<nver angle rounded and about 90 ; when seen from in front the 

 frontal margin longer than the facial margin which is slightly convex 

 and forming a frontal angle about 140^ with it, the outer margin 

 strongly and evenly convex, having the upper and lower angles both 

 about 90 ; facets on nearly the upper two-thirds much larger (about 

 five times) than those on the lower part, and the large facets extend 

 upwards just before the vertex and downwards beyond the junction 

 of the eyes, while the small facets extend in a narrow zone up along 

 the back margin and the contrast in size is rather conspicuous there ; 

 the horizontal dividing line between the large and small facets is not 

 straight but slightly undulating and is rather well-defined. 



Thorax brower than in the female and with longer pubescence
