 distinct; abdomen sliiniug piceous, without bauds or spots, 

 apex fringed with white hairs ; venter piceous. 



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

 at flowers of PhaceUa congesta. Collected hy C II. T. 

 Townsend. Three females. 



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

 known by its small size and the venation. 



Panurginus neomexlcanus^ sp. n. 



^ . — Length about 6^ millini. 



Black, with scanty white pubescence ; clypeus and a very 

 small spot on each side of it pale primrose-yellow. Head 

 somewhat broader than long, face little hairy, mandibles 

 black, anterior edge of clypeus black, front and vertex 

 strongly and very densely punctured ; antennse 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 raetathorax 

 subcancellately wrinkled all over, but the longitudinal 

 wrinkles strongest and most numerous ; tegula shining, very 

 dark brown ; wings rather dusky, nervures and stigma black, 

 first recurrent nervure joining second submarginal cell about 

 the end of its first quarter ; legs black, including tarsi, 

 anterior tibiaj with a short yellow stripe in front j abdomen 

 elongate-cylindrical, sparsely hairy, first segment impunctate 

 on disk. 



Hah. Top of ridge south of Big Rock, Ruidoso, N. M., 

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

 [G. H. T. Townsend). 



This is closely allied to P. Bakeri^ 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^ Or., 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 palaaarctic species, it seems to 

 come nearest to P. Ilerzij Mor., from Eastern Siberia.
