NO. 1979. DESCRIPTIONS OF NEW HYMENOPTERA, 6—CRA WFORD. 243 



Described from five females, some of which have the abdomen ex- 

 tended sufiicient to show the band on segment 5 and others have it 

 completely concealed. 



In VachaFs tables ^ this runs to trinax which is said to have aU the 

 spots on the abdomen large, almost meeting, the truncation of propo- 

 deum not rounded laterally and the wings dirty hyaline. He also 

 mentions maculations only on segments 2 and 3; but as he also says 

 the same for A. caUichroma Cockerell, which in the original description 

 mentions marks on segments 2-5, this may be a typographical error. 



AUGOCHLORA PURA (Say). 



Halictus astios Vachal. 

 Augochlora banksiella Cockerell. 



Mr. Charles Robertson has well redescribed this species and given 

 the earher synonomy ^ and there can be no doubt that he is correct. 

 Specimens from the same set of cells taken at Plummer's Island, 

 Maryland, are either entirely blue-green or distinctly brassy, and this 

 latter is the individual variation described by Professor Cockerell. 

 What Mr. Vachal had under the name pura in his extensive table ^ 

 is undoubtedly in need of a new name. 



The minutely truncate marginal ceU, the keel or tooth on the 

 first ventral segment of the female and the falcate inner hind spur 

 on the posterior tibiae characterize the species of this group. 



In A. pura the keel is subtriangular in outhne and small. 



Superfamily SERPHIDOIDEA. 



TELENOMUS GONIOPIS, new species. 



Female. — Length about 1.12 mm. Black, antennae and femora

 longer than broad, shorter than the pedicel; second joint of funicle 

 subquadrate, joints 3 and 4 transverse, club composed of the last five 

 joints; vertex finely reticulated; in front of anterior ocellus, smooth, 

 pohshed; inner orbits just above level of insertion of antennae with a
