margin ^ith a very broadly triangular smooth impunctate 

 space, the actual margin, which is straight, deeply trans- 

 versely chanriellfed ; antennae entirely black ; vertex finely 

 and quite closely punctured ; mesothoraX closely punctured 

 at sides, but the middle very broadly smooth and shining, 

 with widely scattered punctures ; tegulae with reddish 

 margins. Wings fuliginous ; spurs ferruginous. 



Hub. Huascaray, Peru, 6500 ft., Sept. 21 (C. H. T. 

 Townsend). 



Very close to M. piurensis, Ckll., which is known only in 

 the male. I was at first disposed to regard it as the female 

 of that species, but as the sculpture of the mesothorax is 

 entirely different, and the insect comes from a different 

 locality, it must be presumed to be distinct. Superficially, 

 seen from above, M. huuscari might be taken for a rather 

 small example of M. xylocopoides, Stn. The locality is 

 evidently named after Huascar, to whom I have accordingly 

 dedicated the bee.
