Anthophora optima, sp. n. 
? .—Resembling A. bipartita, Sm., in colour and appear- 
ance, the thorax having black hair in front, fulvous posteriorly, 
and the wings dark fuliginous. It differs from dipartita in 
being considerably larger, length 22°5 mm., anterior wing 17; 
second s.m. very broad, receiving first r.n. beyond middle ; 
hair about ocelli entirely black, with a rusty tint, though 
there is much dull white hair (mixed with black) on face; 
clypeus and labrum without light markings; mandibles 
entirely black ; first abdominal segment fulvous-haired 
(black-haired in bipartita) ; wings darker, not reddish. The 
hair on the legs is entirely black. The ocelli are reddish, 
and in a wider triangle than those of dbipartita. 
In Friese’s key this falls next to A. semirufa, Friese, and 
A. basalis, Sm., but is much larger, and otherwise different.
