of areas are elongate and nearly rectangular ; abdomen petiolate, finely punctured, 

 shining on apical segments; spiracles of petiole placed just back of middle and 

 from these back the petiole is greatly broadened ; second segment depressed, oval 

 and with a large central ridge beneatli ; remaining segments considerably com- 

 pressed, but oval from above and tapering to a point at apex ; ovipositor ventral ; 

 egs slender, coxie elongate, tibise longer than femora and trochanters and tarsi 

 longer than tibiae. 



One specimen from Atlantic City, N. J. (Prof. J. B. Smith). 



Pyrafhiiion idahoeiisis n. sp.
