tate; basal and lateral margins of the tegulae closely punctate, bear- 

 ing coarse black hairs, the disk and posterior margin glabrous, im- 

 punctate 5 small median area of propleura finely punctate and pubes- 

 cent, the surrounding area coarsely punctate ; mesopleura with large 

 distinct punctures throughout; metapleura glabrous, with fine scat- 

 tered punctures, except ventrally with large, coarse punctures ; sides 

 of propodeum with very large, more or less confluent punctures, pos- 

 teriorly the punctures becoming foveate; posterior face and dorsum 

 of propodeum very coarsely, confluently, deeply foveate. 



Abdomen ferruginous, clothed throughout with sparse, black, erect 

 pubescence, except a pair of large obscure, subapical spots on the 

 second tergite with inconspicuous yellowish pubescence ; first segment 

 short, subsessile with the second ; first tergite with scattered punctures 

 throughout, except the apical margin closely punctate ; second tergite 

 with moderate, distinct punctures throughout ; tergite 3-6 with mode- 

 rate, close punctures; tergites 1-6, all with a fringe of long, black 

 pubescence, that of tergite one thinner than those of 2-5; apical 

 tergite very broad and short, the pygidial area occupying the apical 

 third of the tergite but not well defined, the apical margin with a 

 fringe of erect, black hairs; carina of first sternite not dentate, the 

 sternite coarsely, closely punctate ; second sternite with large, distmct, 

 slightly elongate punctures, and a median, longitudinal crest of short, 

 dense, erect, black hairs on the apical half, not extending to the apical 

 margin; sternites 2-5 with small, scattered punctures, denser at the 

 apical margin; sternites 2-5 with a thin apical fringe of black 

 pubescence. 



Legs dark mahogany red, clothed with sparse, black pubescence; 

 calcaria black. 



Wings dark fuliginous; cell 2nd E1 + R2 broadly truncate at the 

 apex ; cell U^ almost obsolete ; vein M.^^ received by cell R5 midway 

 between the base and apex; veins r-m and U- widely separated on 

 vein r; vein r-m conspicuously sinuate. 



Holotype.— Male, Deep Lake, Florida, April 13, 1912, in collection 

 of American Museum of Natural History. 



This is closely related to hexar but may be recognized by being 

 entirely ferruginous. It may prove to be only a variety of bexar. 

 The genitalia of this species are identical with those of asopus and is 

 therefore not figured. 



Group FULVOHIRTA 



The females have the mandibles bidentate; antennal scrobes cari- 

 nate above; thorax short (broader than long in fulvohirta and 

 homole, slightly longer than broad in fulgfida), subhexagonal, and 

 without a scutellar scale ; pygidium rugose. The males have the first
