 WEST UNITED STATES.

(Contribution from the Entomological Laboratory of the Mon- 

 tana State College, Bozeman, Mont.) 



Sabinata new genus. 



Genotype: Sabinata catalina n. sp. Figures i to 5. 



Vestiture of head black except for a few whitish hairs 

 beneath foramen (seen only with difficulty) ; under sides of 

 all femora with very long dense hairs (J* only) ; ventral rows 

 of bristles lacking on all femora ((^ only) ; at least middle 

 and hind tibiae with double beards (J* only) ; anterior tibia 

 with two bristles on distal half of posterior face ; scutellar 

 bridge naked; anterior dorsocentrals and acrostichals pres- 

 ent; four pairs posterior dorsocentrals; apical bristles ab- 

 sent; ventral plates large and extending posteriorly beyond 

 edge of their respective nota ; first genital segment with mar- 

 ginal bristles ; accessory plates abnormally developed. 



Besides the characters noted above, the greater ocellars are 

 unusually strong, and the next to the uppermost pair of frontal 

 bristles is bent forward (away from uppermost pair) in the males 

 of the three known species. The second and third ventral plates 

 are large and almost square; the third is more elongate. Some 

 specimens have a single very slender hair-like bristle in the center 

 of the posterior edge of the scutellum ; others show possible ves- 

 tiges of a pair of apical bristles. 



Sabinata catalina n. sp. 



Holotype (male) : U. S. N. M.; allotype (female) : U. S. 

 N. M. Length: 8 to 13 mm. 



Male. — Parafrontals, genae and transverse impressions sil- 

 very to lead gray; third antennal segment two to two and 

 one-half times length of second ; lateral verticals well de- 

 veloped ; first and third veins with bristles ; in larger speci- 

 mens anterior tibia with posterior beard ; in small specimens 

 with at least some long beard-like hairs toward distal end ; 

 prescutellar acrostichals much weaker than other bristles of 

 mesonotum; three pairs of scutellar marginals; posterior
