second and following tergites of male rather densely punctate. 



aethiops Cresson. 



Scutellum at most sparsely punctate, basal lateral areas polished and im- 



punctate; second and following tergites in male practically impunctate— 9. 



9. Hind tarsus distinctly shorter than tibia, its basal joint about four times as 



long as thick; front and middle femora piceous; propodeal apophyses 



prominent - atripes Rohwer (male) .

 thick ; front and middle femora red ; propodeal apophyses small.

10. Median carinae of propodeum very weak or obsolete ; apophyses small. 



alaskensis Rohwer.

11. Female. — Apical joint of hind tarsus twice as long as second joint (fig. 2a) ; 



basal flagellar joint fully a half longer than second, following joints not 

 nearly twice as long as thick and much thicker at apex than at base 

 (fig. 3a). 



Male. — Apical tarsal joint longer than second joint ; basal flagellar joint 



much longer and distinctly thicker than second (fig. 36) — mellipes (Say). 



Fe^jiaZe.— Apical tarsal joint not nearly twice as long as second (fig. 2&, c) ; 



basal flagellar joint not nearly a half longer than second, following joints 



fully twice as long as thick and nearly or quite cylindrical (fig. 3c, e). 



Male. — Apical tarsal joint not or barely as long as second; basal 

 flagellar joint conspicuously neither longer nor thicker than second 

 (flg. M) 12. 



12. Mesoscutum and scutellum densely punctate; antennae distinctly shorter 



than body, middle joints in female much less than twice as long as 



thick, in male barely twice as long as thick 18.

in male mostly black or piceous vicinus Cresson 



Temples at most only slightly wider than eyes (flg. Ic) ; petiolar area in 

 female fully half as long as horizontal face of propodeum (fig. 4a) ; hind 

 coxae and femora in male red (rarely the coxae and apex of femur are 

 slightly piceous) — 15. 



15. Second tergite regularly longitudinally striate at base striatus, new species. 



Second tergite irregularly transversely wrinkled at extreme base 16.
