858 PROCEEDINGS OF THE NATIONAL Ml'SEUM. vol. xxxr. 



a short, transverse, impressed dash; posterior end and sides of the 

 median segment closel\', coarsely punctured, with a tendenc}' toward 

 ruoosity at tiie sides, particularly in front of the stigma; thickh' cov- 

 ered with many long, brown hairs; the impressed line from the stigma 

 to the postscutellum well developed; that from the stigma to the fovea 

 nearly obsolete; meso- and metapleura more tinely, sparsely punctured 

 than the median segment, bearing numerous long, brown hairs; a spot 

 of yellow pubescence is present above the hind coxa; petiole long, 

 black, considerably curved, minutel}' punctured and bearing long, 

 brown hairs; its hinder portion pale yellowish sericeous. 



Ahdomcm. — Black, ovoid, more pointed in front, flattened beneath; 

 first dorsal plate not rismg sharply from the petiole but nearl}' con- 

 tinuing the petiolar line of curvature; upper surface quite smooth 

 and somewhat glistening, pale sericeous, with a few scattered punc- 

 tui'es and brown hairs on the hinder plates; beneath similar, ])ut with 

 the punctui'es and hairs rather more equally distributed on all the 

 plates; posterior margin of the fourth plate slightly, of the fifth con- 

 siderably emarginate. 



Wings. — Deep fuliginous; cubital vein of the fore wing only very 

 slightly developed beyond the third transverse cubital; discoidal vein 

 of the hind wing not quite interstitial; tegula? yellowish mottled with 

 brown; somewhat 3'ellowish sericeous. 



Legs. — Long, the coxse, trochanters and basal portions of the femora 

 black, the remainder pale ferruginous or yellow, the last tarsal seg- 

 ment darker; coxa3, trochanters and femora with scattered, fine punc- 

 tures and hairs; more or less- yellow sericeous; spines of the tibife and 

 tarsi brown or black, as are also the tips of the claws; tarsi yellow 

 sericeous above; hind tibia? strongly 3'ellow sericeous on the posterior 

 face. 



Male. — Differs as follows: Clypeus more rounded anteriorly, with 

 a slight central notch but no teeth at the sides of it; the margin black; 

 hinder margins of the dorsal abdominal plates pale; the more posterior 

 plates coarsely gray sericeous; usually without pu})escence above the 

 hind coxa^; tibia? often dark brown instead of ferruginous 3'ellow; 

 otherwise differing only in the sexual characters. 



Length. — Females, 17-25 mm.; males, 14-22 mm. 



This species seems to belong to the Upper and Lower Austral life 

 zones of the United States, the most northern captures known to me 

 being at Nyack, New York; Long Island, New York; Jeannette, 

 Pennsylvania; Cedar Point and Sandusky, Ohio. From these locali- 

 ties south it appears to be fairly conunon as far as Chokoloskee, 

 Florida, and Dallas, Texas. Whether it extends nuu-h farther west I 

 can not judge, as several other specimens are labeled ''Tex." without 

 full(M- data. It has not been reported from Kansas, nor does it appear 

 in any of the large collections from the west.
