half as long as broad ; striae at base of second segment close together, as long 

 as the width of the petiole. Legs long and slender; longer spur of hind tibia 

 slightly more than one third the length of the metatarsus; tarsal claws simple, 

 wings slightly tinged with brownish ; radial cell short, about twice as long 

 as the width of the radial vein ; second section of the latter prolonged down- 

 ward as a brown streak ; cubital and discoidal veins visible as pale brown 

 streaks. 



One specimen, Wawai, Washington, May 20, 191 1, A. L. Me- 

 lander. 



This species presents no striking characters, but as indicated in 

 the key to species is distinct ; it seems to come nearest to 6". florissan- 

 tensis Rohwer with a paratype of which I have been able to com- 

 pare it. 



Cryptoserphus Kieffer. 



Kieffer 5 does not place any North American species in this genus, 

 but some undoubtedly belong here as they have the abdominal petiole 

 very short. They do not all show all the other characters attributed 

 to the genus, however, and it may be necessary later to unite Crypto- 

 serphus with Phccnoserphus as has already been suggested by Dodd. 6

C. flavipes Prov. (Fig. 5.) 



Cannot be recognized from his description. As identified by 

 Ashmead, it is easily recognized by its long radial cell and is a 

 Cryptoserphus. I have specimens from Woods Hole, Mass., and 

 Black Rock Mt., Ga. (3,500 ft.). In the far West there is another 

 similar species described as occidentals on a later page of the present 

 paper.
