 terior tibiae reildish on basal third, then dark brown; posterior 

 tarsi dark brown on basal two-thirds ot" 1st joint, then whitish- 

 yellow. Wings infusoated, dark brown in the middle, and usually 

 darker in the 6 than in the 5 ; i'l '^'■e $ the wings show a faint 

 secondary infuscation at the tips, above the third vein ; an area at 

 the base on the inner side nearly hyaline; 3rd vein gently curved 

 above the base of the 1st posterior cell; in the (S the wings are 

 narrower and less I'ounded at the tips, while the terminal section 

 of the 4th posterior vein, closing the 1st posterior cell, is less 

 sinuate and more oblique than in the 2 ; alulae long, narrow, 

 posterior margin straight.

(S . "Very closely resembling^, pulchrifrons, differing as follows: 

 front and broad median facial stripe reaching to the oral margin, 

 metallic black, not steely ; sides of the face, including upper 

 portion, and cheeks deep yellow ; antenniferous process con- 

 siderably smaller, when viewed from above, and no trace of 

 metallic violet spot on the side ; thorax and scutellum more 

 bronzed : pleural stripe orange, much more conspicuous, and rising 

 hisjher on the sides of the dorsum ; 1st segment of the abdomen 

 pure yellow ; 2nd segment considerably narrower and wholly 

 bronze-black except the basal angles, which are yellow ; the yellow 

 markings on the 3rd and 4th segments entirely resembling those 

 on the corresponding segments in the $ of B. pulclnfrons, and 

 not as in the S of that species ; wings longer and narrower ; 

 except at the base, uniformly suffused with brown, not darker in 

 the middle; apical spot above tlie 3rd vein reduced to a mere line, 

 so as to appear as a simi)le continuation of the stigma ; alula; long 

 and rather narrow, with a straiglit posterior edge.
