low hairs and with a pubescent band running from near the front of 

 the teguhe, on the edge of the phite, )>ackward to its hinder margin, 

 then inward along that margin till it barely meets the band from the 

 other side; scutellum black, covered with short, pale j^ellowish hairs; 

 with a hint of a pubescent band along its posterior edge; post scutel- 

 lum narrow, covered with pubescence; median segment thickly clothed 

 with long, 3"ellowish hairs; with a large, squarish, yellow pubescent 

 spot above the petiole, divided on the median line; sides of the thorax 

 sparsely clothed with yellow hairs and with a pubescent spot on the 

 mesopleuron just behind the prothoracic lobe, which extends upward 

 to near the base of the fore wing; beneath rather more densely clothed 

 than on the sides, with longer hairs; petiole short, straight, with pale 

 yellow hairs and with a tendencN^ toward pale yellow pubescence 

 behind; sometimes the dorsum of the median segment shows faint 

 transverse aciculations. 



Ahdomeii. — Black, very finely sericeous, the last four dorsal plates 

 coarsel}' punctured on each side of the middle line; the last two with 

 dark j^ellow hairs; beneath with scattered punctures and long, dark 

 yellow hairs, particularly on the last two plates. 



Wingn. — Fuliginous with a slight violet reflection; the hind wing 

 with the cubital vein bending sharply forward beyond its junction 

 with the discoidal, which is not interstitial, and giving ofl'(in all speci-. 

 mens 1 have seen) a short vein bending back into the median cell; 

 becoming a mere deeper shade beyond the transverse cubital vein; the 

 transverse median vein straight, making more than a right angle with 

 the median vein; tegular partly black, partly dull ferruginous, with 

 slight yellow pubescence on the anterior portion. 



Legs. — Coxje, trochanters, and varying portions of the femora black; 

 the remainder of the legs rusty yellow, the claws darker, their tips 

 black; spines the color of the legs or a little darker; coxa?, trochanters 

 and femora more or less sericeous, the coxte with a few pale hairs; 

 inner contour of the hind tibia straight, the posterior surface strongly 

 pale brownish sericeous; fore metatarsus with nine or ten comb teeth 

 alternating more or less with short spines. 



Male. — Differs from the female in being generally more thickly 

 pubescent and hairy; the last dorsal abdominal plate is narrow from 

 front to rear and its posterior margin is somewhat emarginate its 

 whole width; beneath, the last plate broadly, bluntly rounded, with a 

 short, acuminate point in the middle and a median ridge extending to 

 the anterior margin, across the plate; the anterior margin of the 

 cl3'^peus is rounded, slightly emarginate in the middle, and without 

 teeth. 



Length. — Females, 24-32 nun. ; males, 22-32 mm. 



This species, which is not common, has been captured in Georgia, 

 Mississippi, and Texas, according to the data on the specimens I have
