the legs densely black and covered with black pile. The black band 

 between the wings slightly more than one-half as long (from front 

 to rear) as broad (from wing base to wing base). Tegulae completely 

 surrounded by black pile. 



Abdomen above, with the first two segments densely clothed with 

 yellow pile and the remaining segments covered with rich deep fulvous 

 pile. Ventral surface of abdomen black, except toward and at the 

 apex, where the segments are quite heavily fringed, especially on the 

 side margins, with deep fulvous pile. Coxae, trochanters, femora, and 

 tibiae all black and bearing no light pile ; corbicular fringes black. 

 Tarsi more or less light brown ferruginous. Wings dark, as in 

 B. crotchii Cr. 



$. Length, 17 mm. Like the ?, but smaller. Tegulae not entirely 

 surrounded by black pile, but reached by yellow pile in front. Third 

 antennal segment scarcely equal in length to the fourth and fifth 

 taken together. 



c?. Length. iy l / 2 mm. Eyes greatly swollen, bulging out from the 

 sides of the head. Ocelli large and placed far below the supraorbital 

 line. Malar space very short, not much longer than the pedicel of the 

 antenna. Antennse with third segment fully as long as the fifth, the 

 fourth much shorter than either. 



Head black, but with face below the bases of the antennae rather 

 strongly yellow, black hairs, however, being intermixed. Sides of 

 head behind the eyes black. Occiput rather weakly covered with yellow 

 hairs. 



Thorax with pleura covered with yellow pile to the bases of the 

 legs. Dorsum of thorax entirely and densely covered with yellow 

 except for a broad but rather indefinite (due to the intermingling of 

 the yellow hairs) black band between the bases of the wings. 



Abdomen above with first three segments covered with dull tawny 

 yellow pile. The remaining segments shading off toward the apex of 

 the abdomen into rich fulvous. Abdomen beneath black at base, but, 

 beginning a little behind the middle, the apical margins of the segments 

 are fringed more or less heavily, especially toward the side margins, with 

 fulvous hairs. Coxae and femora all black. Tibiae and metatarsi all 

 black, except their points and the inner sides of the metatarsi, which 

 are light brown ferruginous, as are also the remaining segments of the 

 tarsi.
