Female. — Black: Lab rum, clypeus, mandibles except apices, broad 

 anterior orbits, posterior orbits, scape, first and second flagellar seg- 

 ments almost entirely, posterior border of pronotum and tubercles, 

 tegulae, lateral borders of scutum, lateral spots on scutellum, short 

 fascia on metanotum, several small spots on dorsum of median seg- 

 ment representing a suppressed curved fascia, lateral angles of median 

 segment, fascia of first tergite broken into a pair of large lateral and 

 a pair of small dorsal spots, broad continuous fasciae on tergites 2-5 

 deeply emarginate at anterior middle, ultimate tergite, small lateral 

 spots on sternites 2-5 connected by narrow apical lines, apex of sixth 

 sternite, femora above, tibiae, and tai-si, yellow. 



The wings are distinctly though diffusely infumated. The flagel- 

 Imn below and its ultimate segment apically are yellowish. The 

 coxae are more or less marked with yeUow and the hind pair, as in 

 fodiens, are provided with a distinct tooth on the inner apical margin. 

 The ultimate sternite bears a longitudinal carina and the corre- 

 sponding tergite a well-defined pygidial area set off by distinct lateral 

 ridges. The sternite projects beyond the tergite in a manner similar 

 to that oi fodiens, but it differs in detail from that oi jodiens. The 

 pubescence is exceedingly short and sparse and the puncturing is 

 rather coarse, close, and uniform; it is closest and finest on the 

 scutum, more coarse and scattered on the sixth tergite. 



Length. — 15 mm. 



I have but a single specimen at hand — a female taken at Browns- 

 ville, Texas, by J. C. Crawford.
