the segments ; black area on first segment a very broad band, almost 

 dividing the light laterally ; extreme hind margins of the apical seg- 

 ments light brownish ; apical plate broad, its apical half red ; hind 

 margins of ventral segments broadly pale brown, those of the second 

 and third with a thin covering of white hair. In Robertson's table in 

 ' Canadian Entomologist,' October, 1903, this runs nearest to E. 

 pusillus, but differs in the scutellum, which does not nearly equal the 

 lateral teeth, and in the partly black legs. According to Brues, 

 pusillus has the teeth at the sides of the scutellum red, as in venwnia; ; 

 but Ci-esson makes no mention of this, and it seems unlikely that he 

 would overlook such a conspicuous character. Cresson also describes 

 the abdominal bands of pusillus as cinereous, whereas in vernonm they 

 are very strongly yellow. The antennae of pusillus are said to be red 

 basally ; in vernonicR they are black, only the extreme base of the scape 

 showing a little reddish. With all this, vernonicB may be a race of 

 pusillus, but in the absence of any proof I leave it as distinct.

Epeolus virginiensis , sp. nov. 



^ . Length 9 mm. or a little less. A small species similar to 

 vernonice, but differing as follows : Eyes light green (light reddish in 

 vernonicB) ; mandibles darker, the basal half black, the apical dark 

 reddish ; thorax smaller ; stripes of mesothorax connecting with bands 

 which run along the anterior margin and curve back to the tegulse (no 

 such bands in vernonia) ; tubercles and axillar spines black, ^he latter 

 very much smaller, not nearly reaching the level of end of scutellum ; 

 pleura thinly overspread with hair, except just below the wings ; tegulcB 

 piceous, a little reddish behind ; wings dusky, the apical margin not 

 contrasting, stigma rufo-fuscous ; all the femora black, except the 

 knees ; anterior tibiae black, except at ends ; middle and hind tibiae 

 red, the latter with a dusky shade in front ; abdomen somewhat nar- 

 rower, the bands perhaps not quite so yellow ; band on apex of first 

 segment interrupted, and that on apex of second with a linear inter- 

 ruption ; apical plate only about half as broad. The mandibles are 

 simple, and the spurs are black. 



Hab. Falls Church, Virginia, September 7th (Nathan Banks). 



At Glencarlyn, Virginia, September 6th, Mr. Banks took 

 E. autumnalis, Bob. ; new to Virginia. 



Panurginus virginicus, sp. nov. 

 <?. Length about 5 mm.; black, with the general stature and 

 appearance of P. pauper (Cresson), but easily distinguished by the 

 lemon-yellow face markings, and especially by the large quadrate 

 head, with the face very wide. Clypeus, lateral face-marks, labrum, 

 mandibles (except the ferruginous tips), all yellow ; but no supra- 

 clypeal mark. Lateral marks pyriform, not extending above level of 

 clypeus, the point directed toward the malar region ; clypeus well 

 punctured all over ; flagellum long, testaceous beneath except at apex 

 and extreme base ; mesothorax nude, very minutely and closely punc- 

 tured, the median groove strong ; tubercles and tegulae testaceous ;
