triangular, narrowing to a point above ; third discoidal 

 distinct; abdomen shining piceous, without bauds or spots, 

 apex fringed with white hairs ; venter piceous. 



Hab. La Cueva, Organ Mountains, N. M., Sept. 2, 1898, 

 at flowers of Phacelia congesta. Collected by 0. H. T. 

 Townsend. Three females. 



P. phacelite is related to P. ceneifrons, but will be easily 

 known by its small size and the venation.

Black, with scanty white pubescence ; clypeus and a very

 black, anterior edge of clypeus black, front and vertex 

 strongly and very densely punctured ; antennae quite long, 

 wholly black, scape punctured ; mesothorax with strong punc- 

 tures of unequal size, becoming sparse on the shining disk ; 

 scutellum with punctures of unequal size ; base of metathorax 

 subcancellately wrinkled all over, but the longitudinal

 about 7400 feet, Aug. 3, 1898, at flowers of Solidago 

 {C. H. T. Townsend). 



This is closely allied to P. JBakeri } but is readily distin- 

 guished by the small spot on each side of clypeus, black 

 anterior edge of clypeus, and especially the sparsely punc- 

 tured middle part of mesothorax. From P. picipes } (Jr., it 

 will be known by the scanty pubescence, lateral face-marks 

 reduced to a spot, mesothorax without a well-impressed central 

 line, black tarsi, &c. Of the pahearctic species, it seems to 

 come nearest to P. Ilerzi, Mor., from Eastern {Siberia.
