outer upper edge at base; scutellum unusually small, flat; apex of pos- 

 terior tibiae and the posterior tarsi blackish; ovipositor sheaths slender

 flattened area at base; posterior femora, tibiae and tarsi wholly testa- 

 ceous; scutellum large, flat; ovipositor sheaths broad and two-thirds as 

 long as the abdomen 18. gelecMae Riley. 



19. Ovipositor sheaths hardly one-fourth as long as the abdomen and very 



slender; mesoscutum entirely, and the scutellum with distinct scattered 



shallow punctures 19. swammerdamiae, new species. 



Ovipositor sheaths at least half as long as the abdomen ; mesoscutum 

 posteriorly. r>nd scutellum impunctat-" and polished 20. 



20. Third abdominal tergite smooth ; first tergite usually shorter than broad 



at apex ; also usually shorter than the dorsum of the abdomen beyond 



second tergite; coxae always wholly black 21. 



Third abdominal tergite somewhat roughened, first tergite usually longer 

 than broad at apex, and usually longer than dorsum of abdomen beyond 

 second tergite; occasionally all coxae are pale at apex 23. 



21. Venter of abdomen mostly yellowish; stigma pale brown witliout a paler 



spot at base; ovipositor sheaths distinctly two-third as long as the 



abdomen 20. carinata Packard. 



Venter of abdomen black ; stigma dark brown with a paler spot at base ; 

 ovipositor sheaths not more than half as long as the abdomen 22. 



22. Face shallowly weakly punctate and strongly shining; clypeus almost im- 

 • punctate ; posterior tibiae and tarsi pale testaceous ; posterior margin of 



second tergite straight 21. comptanae Viereck. 



Face and clypeus finely ruguloso-punctate and opaque; posterior tibiae at 

 apex and tlie posterior tarsi blackish ; posterior margin of second tergite 

 curving forward at the sides 22. canadensis, new species. 



23. All femora mostly black or blackish 23. femoralis, new species. 



All femora testaceous 24. 



24. Face very weakly punctate and shining, and without a distinct median 



carina extending from antennal fossae nearly half way to the clypeus, at 

 most with a small polished tubercle below antennal fossae ; clypeus almost 



impunctate 24. phthorimaeae, new species. 



Face and clyeus very finely rugulose, with a prominent median polished 

 carina extending from antennal fossae nearly halfway to the clypeus- 25. 



25. Extreme apex of all coxae, and the trochanters pale; venter of abdomen 



yellowish on basal lialf ; stigma unicolorous ; fore wing without a fuscous 



spot across radius just below stigma 25. epagoges Gahan. 



Coxae entirely, and the basal segment of trochanters, black; venter of
