THE BEES WITH BIFID TONGUES 



IN this country we have only two genera in 

 which the tongue is bifid at the apex, and on 

 this account they are kept together as close allies 

 in our classification. They are, however, very 

 different in general appearance. One of these 

 groups is called Colletes, on account of its habit 

 of lining its cells with a gluey material, the 

 other, Prosopis, on account of the markings on 

 the face. The various kinds of Colletes are densely 

 clothed on the head and thorax with brownish 

 hairs, and the segments of the body have whitish 

 bands composed of a dense, tight-fitting, duvet 

 of hairs (pi. B, 10). There is in this country 

 only one exception, a large insect like a hive 

 bee, but rarely met with, its headquarters 

 being the Wallasey Sandhills near Liverpool, and 

 other localities in Lancashire. All the species 

 tend to colonize ; some building in huge colonies
