The male of this species resembles that of S. f-avopicta (Cresson) in 

 having the antennal scape extremely large (as in fig. 9, 1) with the apex 

 exceeding the level of the vertex, but differs in that the malar space is 

 less than two-thirds the height of the compound eye, the petiole has 

 rhe basal flange, from the lateral aspect, appearing to be at an angle 

 of 60° to 70°, not at 90° ; in both flavopk-ta and this species, the prox- 

 imal, nonfused part of the penis valve is short and stout, but it is 

 somewhat more rounded in this species (fig. 14, Tc)^ and the distal por- 

 tion is slenderer in this species than in jiavopicta. The female of 

 ■sanguineiventri-s is the only one of the side group having the antennae 

 inserted dorsad of the ventral margins of the compound eyes, and the 

 epipygium, which is equal to or shorter than the eighth tergite, will 

 separate it from the female of fiavopicta. 



De^ci^ption. — Male: 2.5-4 mm. Antennal scape stout, exceeding 

 level of posterior ocelli, pedicel twice as long, and ring segment one- 

 third as long as segment 4, segments 4 to 10 equal, last three shorter, 

 sutures obscured by long, moderately dense setae ; scrobe cavity shal- 

 low, margin acarinate, a glabrous patch present just dorsolaterad 

 of each antennal base ; width of malar space varying from three-fifths 

 to almost two-thirds height of compound eye: combined widths of 

 compound eyes three-fourths interocular space at level of apex of 

 interantemial projection; diameter of posterior ocellus one-third 

 interocellar space ; width of head, from dorsal aspect, usually equal to 

 maximtun dorsal width of thorax. 



Prepectus completely concealed by projecting angle of mesoscuttmi : 

 apex of mesoscutellum with a mmute, mesally depressed lamina; 

 metepisternum irregularly pitted, ventral pits larger than dorsal ones ;
