 broadly oval, with a length about twice its width. Type Cecid 1401. 



This species was taken May 16, 1910, by Dr. W. G. Dietz, at 

 Hazelton, Pa. It is allied to P. tuckeri Felt, from which it is easily 

 separated by the stouter antennal segments and the broader lobes of 

 the ovipositor.

This species was taken June 4, 1910, at Hazelton, Pa., by Dr. \V. 

 G. Dietz. It is closely allied to P. porrccta from which it is easily 

 separated by the black mesonotum and the perceptibly shorter terminal 

 segments of the antennae and palpi.

Female. — Length 1.3 mm. Antennae a little shorter than the body, sparsely 

 haired, fuscous yellowish ; 12 segments, the fifth with a stem about Yi the 

 length of the cylindric basal enlargement, which latter has a length about four 

 times its diameter ; terminal segment greatly produced, with a length fully six 

 times its diameter. Palpi ; first segment slender, with a length five times its 

 diameter, the second segment as long as the first, stouter, the third as long as 

 the second, more slender, the fourth Y2 longer than the third, very slender. 

 Face fuscous yellowish, mouth reddish. Mesonotum dark brown, the sub-

 and sparsely clothed with long setae. Type Cecid ai628.
