basal cell and narrowly the posterior margin of the second 
basal cell. The costal cell is entirely pale brown, becom- 
ing darker towards the apex. 
Abdomen : of the usual shape, except that it is perhaps 
somewhat more tapered posteriorly ; it is quite broad 
basally and distinctly wider than the thorax and begins 
to rapidly narrow from the base of the second segment 
so that the shape is that of a short wedge-shaped triangle. 
The first, second and third segments are black or nearly 
so; in some lights close scrutiny suggests that the second 
segment and the third segment have a slight appearance 
of dark reddish sepia, which is almost black in color. The 
fourth segment is blackish basally, but becomes very dark 
mahogany reddish posteriorly; this is especially apparent 
when this segment is viewed from the rear; actually the 
fourth segment is also very dark and might be called 
black. The pile of the abdomen is dense, short, subap- 
pressed and black, but longer on the sides of the first 
and second segments; on the fourth segment it is ap- 
pressed, short, abundant and golden reddish in color. The 
lateral pile along the extreme margin of the third seg- 
ment is also golden. Hypopygium dark reddish brown 
with golden pile. 
Holotype: male, Chisos Mts., Big Bend National Park, 
Texas; collected by J. Bequaert. I take pleasure in nam- 
ing this handsome species in honor of its collector.
