72 PROCEEDINGS OF TEE NATIONAL MUSEUM. vol. 52. 



male is for the most part black, that of the female largely ferrugi- 

 nous. One female bears a yellow spot on the mesopleurae. The facia 

 on the first tergite is broadest and all are but slightly narrowed toward 

 the median line; they do not reach the lateral edge of the segments 

 and the more posterior ones may appear as elongated lateral spots. 



The female of his species may be distinguished from the female of 

 ventralis by the presence of the ferruginous markings on the legs, 

 antennae, and terminal segment and also by the fact that the first ab- 

 dominal fascia is the one best developed in this species and most re- 

 duced in ventralis; from fodiens and capnoptera by the absence of a 

 pygidial area and lateral lines on the ultimate tergite. The male can 

 be distinguished from ventralis by the absence of a tooth on the inter- 

 mediate femora ; f rom fodiens by the absence of a tooth on the posterior 

 coxae, and from canoptera by the form of the genital stipes. 



Habitat. — Texas, Florida, New Mexico. 



Number of specimens examined — Males, 6; females, 5.

Male. — Black: Labrum (in some specimens ferruginous, in others 

 black), clypeus (may be wholly or in part black), scape below, basal 

 joints of flagellum below, anterior orbits, narrow posterior border of 

 pronotum continuous with tubercles and narrow line on side of 

 prothorax, lateral lines on scutum above base of wings, tegulae, 

 lateral spots on scutellum, fascia on met ano turn, lateral angles of 

 median segment, fasciae on tergites 1-6 all interrupted medially, 

 the more posterior ones usually shortened or narrowed laterally, 

 lateral spots on sternites 2-6, which may be connected by narrow 

 apical lines, yellow more or less dashed or suffused with ferruginous. 

 Legs ferruginous with the coxae and more or less of the basal part of 

 the femora much darker, sometimes black. 



Segments 4-11 of the flagellum have raised specialized areas on 

 the posterior surface, which, when viewed from a certain angle, 

 cause the flagellum to appear slightly carinate. The wings as in 

 ventralis are strongly infumated. The femora of the second pair of 

 legs are not toothed but are carinate and slightly angular at the 

 base below. 



Female. — Black: Clypeus, labrum usually, spot between antennae, 

 scape below, basal segments of flagellum below, anterior orbits, 

 narrow posterior orbits, posterior border of pronotum continuous 

 with tubercles and line on side of prothorax, lateral lines on scutum 

 above base of wings, lateral spots on scutellum, fascia on metano-
