are narrowly interrupted anteriorly, more widely posteriorly; the 

 anterior ones well developed, the posterior abbreviated; present on 

 1-4 and sometimes 5 in the female, on 1-5 and sometimes 6 in the 

 male. The lateral spots on the sternites vary in size and also in 

 number. They are usually found on 2-4 in the female, but occasion- 

 ally are present on 5; in the males on 2-5, but may occur on 6 or be 

 reduced to 2-4. In the case of two very light females from Kansas 

 the lateral spots are present on 1-5 and sternite 2 is almost entirely 

 yellow. 



The terminal tergite of the female lacks a pygidial area, but short, 

 feebly marked lateral ridges are present. The apical sternite is lon- 

 gitudinally carinate on the median line and throughout its apical half 

 it narrowly extends laterally beyond the tergite, which is roundly 

 triangular apically. 



Two males, which I have referred to this species, were collected by 

 Mr. Ashmead in New Mexico and were referred by Fox to B. variegata 

 Olivier. These males differ from the typical male of quadrifasciata 

 only in the possession of more extensive maculations; in other re- 

 pects, including the genitalia, there is no essential difference. 

 B. variegata Olivier was described from South America, and the genital 

 stipites of the male are quite different from those of quadrifasciata, as 

 is shown by a comparison of figures 117, 118, 119 and 120, of which 

 119 and 120 represent the stipites of a male of variegata taken in Vene- 

 zuela.

Female. — Black: Labrum, clypeus, mandibles except apices, scape 

 except spot on upper side, first joint of flagellum below, second al- 

 most entirely, lower part of frons, narrow vertical line in front of 

 anterior ocellus, broad anterior orbits, posterior orbits narrowed 

 above, broad below, and extended somewhat upon the vertex toward 

 the posterior ocelli, prothorax except narrow anterior border con- 

 nected with spot in front of tubercles, tegulae, broad lateral fines 

 on scutum, pair of discal spots on same, pair of large lateral spots 

 on scutellum approximated at median line, metanotum, curved 

 fascia on dorsum of median segment, lateral angles of median seg- 

 ment, mesopleurae almost completely, spot on metapleurae, broad 

 fasciae on tergites 1-5, continuous but with an acute triangular 

 emargination medially, fasciae on sternites 2-5 continuous, triangular 

 lateral spots on ultimate tergite, ultimate sternite, and legs almost 

 entirely, bright yellow. The coxae basally are more or less marked
