CALLIPHORA GRAHAMl, new species 



Of the size and appearance of vomitoria Linnaeus, but having in 

 both sexes no inner presutural bristle (presutural intraalar of Hough,, 

 hindmost sublateral of Shannon), beard wholly black, gray pollen 

 of thorax and abdomen considerably more dense; the male also dif- 

 fers in having the front about three times as wide (0.14 of head width 

 below front ocellus), and the genitalia greatly enlarged and of quite 

 unique form. 



The abdomen of the male is short and broad and the shining black 

 genital segments (fig. 1) are very large, the first vertical, the second 

 extending forward more than halfway to the base of the abdomen; 

 first visible sternite short, second longer than usual, third and fourth 

 short, curving downward, the fourth with more dense pile than pre- 

 ceding. Fifth prominent at base and bearing a dense tuft of short 

 spines each side of middle line, not much separated ; lobes large and 

 widely divergent, the large median concavity bearing tv\"o long paral- 

 lel lobes of soft structure, their tips turned outward, which are sepa-
