This common species is most easily recognized in the male by the 

 broadl}^ rounded vertex, the antennae inserted slightly dorsad of the 

 ventral margins of the compound eyes, with the apex of the scape 

 not exceeding the level of the posterior ocelli, the elongate pedicel 

 (fig. 9, m) and the entire frons ventrad of the antennal bases being 

 yellovt'. The female is recognized by its broadly rounded vertex, the 

 basolateral areas of the propodeum being shagreened rather than 

 carinate, and the basal tergites of the gaster rufous or red. 



Description. — Male : 3-4 mm. Antennae inserted sliglitly dorsad of 

 ventral margins of compound eyes, scape (fig. 9, m) not exceeding 

 level of posterior ocelli, pedicel always at least one and one-half times 

 as long as segment 4, often nearly twice as long, ring segment one- 

 half length of segment 4, flagellar segments variable, 4 to 7 usually 

 equal, 8 to 12 slightly longer, 13 equal to 7; scrobe cavity shallow, 

 margin acarinate, a glabrous spot present in scrobe cavity just dorsad 

 of each antennal base ; frons minutely shagreened, provided with con- 

 spicuous white pubescence; interantennal projection minutely carinate; 

 malar space one-half height of compound eye ; left mandible with two 

 acute teeth, right with three; combined widths of compound eyes 

 equal to or slightly greater than interocular width at level of antennal 

 bases : diameter of posterior ocellus slightly more than one-third width 

 of interocellar space. 



Dorsum of thorax shallowly and irregularly pitted, areas around 

 parapsidal furrows impunctate; pubescence stout, white; antero- 

 lateral angles of pronotum slightly produced ; anterior dorsal margin 

 acarinate ; prepectus narrow, reaching tegula ; apex of mesoscutellum 

 provided with a narrow, mesally depressed lamina; metepisternum 

 shagreened, surface provided with large shallow punctuies; meta- 

 coxae shagreened on outer dorsal side, obscurely punctured and 

 setose on outer ventral surface; metafemora minutely reticulated, 

 sparsely covered with short setae; outer ventral margin vrith 14 to 

 18 minute teeth, basal one larger and slightly blunted; small inner 

 tooth present. 



Propodeum usually entirely without setae, a few sometimes pres- 

 ent at sides, surface shagreened, mesal and apical carinae present, a 

 minute lateral projection at each posterolateral angle, spiracular
