174 Mr. E. Saunders' Synopsis of 



5 . Larger than the <? , with the parts of the face which are

 except the basal joint, which is black above. Thorax clothed with 

 short reddish hairs ; tubercles yellow ; tegulse testaceous ; scutelhim 

 with two yellow tubercles. Abdomen coloured as in the <? ; legs 

 fulvous-red ; posterior femora black ; posterior tibiae armed at the

Hab. Hampstead, Highgate, Scotland, Devonshire. 



P. Smith says it has been observed about the burrows 

 oi Andrena labialis, and also those of "A. riifa'' {? A. 

 fulva). Schmiedeknecht, in his ' Apidge Europaese,' says 

 it is parasitic on Andrena pratensis ; so that probably, 

 as Smith remarks, it is one of those bees that are para- 

 sitic on several species.
