Hah. — Piura, Peru, February, 1911 ; one female, three males 

 taken from nest (C. H. T. Townsend, 1124). The cells are 

 covered with leaves in the usual manner, and the whole has a 

 diameter of about 8 mm. The bee has taken portions of small 

 leaves, each showing a midrib. A neat little species, quite 

 closely related (male) to M. lenticula, Vachal, but the latter is 

 larger, with black legs, and a very long pale yellow beard on 

 cheeks below, the cheeks of philinca having a very short white 

 beard. The type of 'philinca is the female. I have sent a male 

 M. philinca to the British Museum. 



Trichocolletes, gen. nov. 



Eesembling ParacoUetes, but the eyes clothed with very long 

 hair ; stigma rudimentary.
