290 BRITISH BEES. 



The MALE differs in the antenna being rather longer, 

 more distinctly filiform, the seventh segment of the 

 abdomen concealed under the extremity of the sixth, and 

 the venter from the third segment longitudinally deeply 

 concave, the plate of the third itself covered with hair ; the 

 claws more robust and each equally bifid, not bidentate.

GENERAL OBSERVATIONS. 



The names of insects are not always very aptly given, 

 for the only available derivation of this appears to he 

 from 'ipwv, wool; in allusion to the clothing of its 

 venter ; but, if so, it should be spelt without the H, for 

 the first letter is without an aspiration. The habits of 

 these closely resemble those of the preceding genus, to 

 which they have a great personal likeness, and therefore 

 their natural history would be but its reiteration. Our 

 solitary species is a rare insect, but I expect western 

 England would produce it. It is like those of the pre- 

 ceding genus, of a uniform black colour, punctured, 

 but it approximates more closely than they do to the type 

 of form exhibited in the genus Osmia. They visit the 

 same flowers as the preceding genus.
