664 Mr. T. D. A. Cockerell— Descriptions and 
Osmia cornifrons (Radoszkowski). 
This species, from Korea, was published as a Chalicodoma, 
and was referred by Friese as a synonym of O. taurus, 
Smith. In the British Museum I found Smith’s taurus 
aud a cotype of cornifrons. The facial horns in cornifrons 
are much more widely separated, and finger-like instead of 
subtriangular, The abdomen is very hairy. They are 
certainly different species. 
Osmia simillima, Smith. 
I noted at British Museum: type (?, Nova Scotia) of 
simillima looks exactly like type (¢, Florida) of O. chalybea, 
Smith; but in simillima the basal nervure goes a little basad 
of nervulus, in chalybea the reverse is true. 
Anthophora acervorum (L.). 
Linneeus described his Apis acervorum from the black 
female, which Frieze calls var. niger. ‘The species is, how- 
ever, very variable, and the specimens before me may be 
separated thus :—
