By A. A. GIRAULT, Glenn Dale, Maryland. 



Scrobes forming a semicircle. Head densely scaly. Wings hyaline. 

 Mandibles stout, with three nearly equal teeth. 



First two pairs of legs yellow except coxae. Scape concolorous. 

 Ovipositor extruded for two-thirds the length of the abdomen, 

 somewhat compressed. Body densely scaly. Dark metallic blue. 

 Tegulae blue. 



Hind legs concolorous except proximal three tarsal joints; mar- 

 ginal vein nearly twice longer than wide, a little shorter than 

 the postmarginal, the latter a little over half the length of 

 the stigmal; frons moderate, with several rows of minute punc- 

 tures on each side; scape slender, very slightly, linearly exfoliat- 

 ed ventrad; pedicel nearly twice longer than wide. Lower 

 face with obscure thimble punctures. A trace of yellow against 

 the marginal vein; venation yellow brown. Elongate, 



pallipes Provancher. 



Middle legs entirely yellow except the coxae, the other femora more 

 or less concolorous. 



Scape concolorous. Legs fuscous except the cephalic femora 

 (washed), hind femora except at each end and the coxae; funicle 

 i shorter than 2 by a half. No scrobes. Ovipositor as long 

 as the abdomen ............................ caudatus Cameron. 



Scape honey yellow: ovipositor valves broad, testaceous as is the 

 venation. Flagellum brown-black. Base of cephalic femora, 

 basal two-thirds of hind femora and all coxae concolorous, the

 tarsi white, the legs reddish; scape with a moderate ventral
