 tiguous punctures throughout, the apical margin confluently punctate, 

 sparsely clothed with erect, pale hairs and a tliin apical fringe of 

 silvery pubescence ; sternites 3-5 moderately, confluently punctate, the

Holotype. — Female, Baboquivaria Mountains, Ariz. (F. H. Snow), 

 in collection of University of Kansas. 



Belated and similar in appearance to eurynome and honita. May 

 be easily separated from the two latter by the coarse puncturation of 

 the genae, the black pubescence of the vertex and thoracic notum, 

 the basal spot of black pubescence on the second tergite, the indis- 

 tinct maculation of the latter, and the row of submarginal bristle- 

 like hairs of the first tergite. 



Group MONTICOLA 



Males black, the second abdominal segment more or less ferrugi- 

 nous; small, not over 10 mm.; apical abdominal tergites incon- 

 spicuously clothed with silvery gray pubescence; anterior margin 

 of pronotum more or less emarginate medially, the cephalic face of 

 the emargination glabrous; second abdominal sternite either with 

 or without a median pit densely filled with hairs. Females unknown, 

 probably included in the preceding group.
