Six specimens agree sufficiently well with the descrip- 

 tion of this species. In those that are well preserved, 

 there is a golden pubescence on the abdomen, and the 

 hind femora may be in large part black. With these 

 specimens, there are several others in which the thorax 

 is yellow, with the mesonotum brownish. The abdomen, 

 in all the specimens, is in large part black.
