eral ocellus ; there is usually an impressed line from the anterior ocel- 

 lus backward to the crescent-shaped line ; from the anterior ocellus to 

 between the bases of the antennae is a line like carina, which is more 

 distinct between the antennas. The antennae thicken toward the apex; 

 the third joint is longer than the fourth, but is not as long as the 

 fourth and fifth combined. Dorsulum punctured, in some places the 

 punctures are confluent giving it a striated appearance ; the central por- 

 tion of the scutellum shining, polished, with a few scattered punctures ; 

 the sutures bounding the scutellum are deep, the one between the dor- 

 sulum and the scutellum foveolate ; mesopleurae shining with some scat- 

 tered punctures; the enclosure of the metathorax clearly denned, loygi- 

 tudinally striate, the diamond-shaped fovea with some rugae, posterior 

 face punctured; metapleuree shining. The second cubital cell slightly 

 narrowed above; the second recurrent nervure interstitial or nearly so 

 with the second transverse cubitus. The petiole of the abdomen about 

 the same length as the hind trochanters and femora, slightly thicken- 

 ed toward the apex, sub-convex above with two more or less distinct 

 longitudinal sulci. Pygidium long shining, with a few large punctures, 

 surrounded by a strong carina. Color black; the apical joints Of the 

 palpi and the tarsi testaceous (in some specimens brownish) ; the face 

 below the antennae with dense silvery pubescence ; thorax with a few 

 scattered hairs; the base of the hind tibiae with a bunch of silvery 

 hairs. Wings clear, glassy, hyaline, iridescent ; venation pale brown, 

 stigma dark or pale brown. 



Male. Length 7 to 7.5 mm. Anterior margin of the clypeus gently 

 rounded, not emarginate. Antennae somewhat moniliform, but not 

 strongly so. Petiole rather longer than in the female. The apex of 

 the abdomen has a curved spine. In general the male is like the female 

 but the sculpture is somewhat coarser. 



Type locality. Wetzel's Swamp, near Harrisburg, Pa. 

 Many cocoons collected by P. R. Myers, September 28, 1908; 

 the adults hatching in January and February, 1909. 



In the bidentate clypeus of the female this species is related 

 to bar t hi Vier. ; but the wings are clear hyaline, the scutellum 

 is only sparsely punctured, and there are no steel-blue reflec- 

 tions from the thorax. It is also related to simplicicornis Fox, 

 but the female has the clypeus different, and the pygidium sur- 

 rounded by a strong carina. The male has the front more 

 finely punctured than the male of simplicicornis, which is very 

 closely allied, and the antennae are somewhat moniliform.
