Peckham—Revision of the Attidce of North America. 375 
We have two females from the southern part of Texas, near 
the Mexican border. 
Under alcohol this species resembles B. micans, since the 
bright color of the latter appears only after drying. In both, 
the tibia of the first leg is enlarged, but the character of the 
fringe is different, and while in Wheelerii this joint is longer 
than the femur, and is plainly longer than wide, in micans it is 
not longer than the femur, and is about as wide as long. 
This species is named for Prof. Wm. Morton Wheeler.

In the female the cephalothorax has a small semi-circular re¬ 
gion behind the dorsal eyes which falls but little below the plane 
of the cephalic part, and from this there is an abrupt slope to 
the lower border. In the male the distinction between the two 
inclinations is not so clearly defined, the effect being a gradual 
slope from the dorsal eyes. Palces, o , usually horizontal and 
three times as long as face, sometimes nearly vertical and only 
twice as long as the face, rounded on the outer side, straight 
within, having a long tooth on the distal lower edge and three 
teeth on the upper edge, transversely rugose above; 9 , vertical, 
but little longer than the face. Sternum oval, projecting be¬ 
tween the anterior coxae, which are separated by the width of 
the labium. Labium a little longer than wide. 
The ground color of the body is black, the cephalothorax 
being covered with slightly iridescent white scales which have
