DESCRIPTION. 



Body ovate, reddish-yellow : segments, particularly the first of the trunk, pectinated with black 

 bristles ; antenna; though short very distinct, standing out from the head, they seem to consist of 

 two joints, the last conical and obtuse ; the base of the second segment of the trunk is black ; the 

 thighs are very flat and wide, inclining to ovate ; tibia; armed with long black bristles. 



This I believe is the largest flea known, but I have not been able to ascertain upon what animal 

 it was captured.
