 superiors split with two transversal rows of strong black spines ; below

 hairs, tip of tibia, of third and apical joint of tarsus black, fourth entirely 

 black ; spurs brown, incurved, as long as the two basal joints. 



Wings hyaline, pterostigma small, yellowish white, interiorly a dark 

 dot ; only the last costals before it forked ; venation dark, largely inter- 

 rupted with white ; along the mediana and submediana the costals marked 

 with dark, also the base of the small forks on the apical and hind margin 

 of the front wings. 



Length of body, male 35 m.m. ; female 25 m.m. ; exp. al., 45 to 50 

 m.m.

It has the appearance of a smaller form of B. peregrimis. A larger 

 male, length 38 m.m., exp. al. 60 m.m., is apparently just transformed, 

 with the colors not yet finished, from Tusco, Arizona. I can not separate 

 it from the Texan species.
