gination of the eyes except a small black spot immediately above the insertioi. 

 of the antennae, scape below and first joint of fiagellum below, lemon-yellow; 

 a ferruginous spot back of the eyes. Thorax entirely black, shining; prono- 

 tum, mesoscutum, mesoscutellum and metanotum very sparsely punctate, 

 appearing almost impunctate; episterna and propodeum entirely with fine, 

 rather sparse punctures; tegulae yellowish. Abdomen above, black, shining, 

 with a few scattered punctures, the apical tergite closely and minutely punc- 

 tured interspersed with a few larger, scattered punctures; venter finely and 

 minutely punctured with a few larger, scattered punctures; basal segment of 

 abdomen entirely ferruginous except a narrow, apical margin above, black; 

 the basal two-thirds of the second abdominal sternite ferruginous, the second 

 tergite with the narrow, basal margin ferruginous, a transverse, broad, yellow 

 band and the narrow, apical margin, black; remainder of the abdomen entirely 

 black. All the coxae and trochanters black; the femora black on the basal 

 half, ferruginous on the apical half; tibiae and tarsi ferruginous. Wings 

 yellowish, darker at the tips; nervures testaceous; cubitus in posterior wings 

 interstitial with the transverse median nervure. 



Type, a female taken at Fort Garland, Colorado, August 9, 

 (L. Brunei"). This specimen is 18 mm. long. It is over cyanided 

 so that the yellow on the head and abdomen appears reddish. 

 One paratype, Ute Creek, Colorado, Sage Flats, August 14, 

 (L. Bruner). This specimen is 23 mm. long. 



A very distinct species. The shining, almost impunctate 

 body, the entirely black thorax and the coloration of the abdomen 

 will serve to distinguish it.
