Epeolus bihamatus, sp. n. 



cJ. — Size, colour, and general appearance agreeing with 

 E. argijreus, with the same silvery hair covering the pleura, 

 though not quite so densely, and also on the face, though 

 failing below, so as to leave the lower part of the very minutely 

 and densely punctured clyj)eus visible. The black spurs also 

 are the same, and the hyaline wings. The following differ- 

 ences are important : — Mandibles with more red ; margin of 

 labrum red ; face less narrowed below ; third antennal joint 

 longer ; flagellum ferruginous beneath except at base ; meso- 

 thorax less hairy, leaving a large anchor-shaped black area 

 very densely punctured, its stem reaching the anterior margin ; 

 tegula3 j)iceous basally, red in the middle, and with hyaline 

 margin ; area of metathorax almost entirely covered with 

 hair; marginal cell less slender; second t.-c. complete; 

 knees, femora, and tibire red ; transverse band on first abdo- 

 minal segment large and clean-cut; band on second segment 

 with a large hook-like process on each side; erect fringe on 

 fourth and fifth ventral segments white.

This species and the last are very distinct by the general 

 appearance and hairy pleura, together with the black spurs, 

 from the other American members of the ^lenus. 



The following three species of Triepeolus superficially 

 resemble T. luuatus and heliantlii, and weie confused with
