OsMIA FUSCIFORMIS. 
Osmia fusciformis, Lair. Encyl. Meth . 8, 595. 
Female (length lines). Black: head and thorax closely 
punctured, the anterior margin of the clypeus entire, the face 
sparingly clothed with black hairs ; those on the occiput are rufo- 
fulvous, as is also the pubescence on the disk of the thorax and on 
the two basal segments of the abdomen ; the pubescence on the rest 
of the segments black ; the entire pubescence of the legs, and also 
that on the abdomen beneath black : the pubescence on the basal 
joint of the posterior tarsi within, slightly reddish ; the tips of the 
wings are slightly clouded. 
The male has not hitherto been captured in this country : the 
following is its description by Latreille: — 
The antennae of the male are not much longer than those of 
the female ; the down of the head, and all the upper part of the 
body rufous ; the hairs of the clypeus are paler, and the intermediate 
rings of the abdomen are less hairy at their base ; the hairs on the 
lower sides of the head and of the legs, the two first especially, are 
gray ; the sixth segment of the abdomen is rounded on the sides, 
and slightly notched in the middle of the apical margin ; the 
seventh has a deep cut, which makes it appear bidentate.
