22 PEOCEEDINGS OF THE NATIONAL MUSEUM Vol.68 



anterior forceps are more stronglj^ curved forward, beginning to 

 taper at about the middle and have on the hind edge, somewhat 

 before the tip, a distinct groove on the inner side. 



The female, if I have associated it correctly, has on the last genital 

 segment a square shoulder on each side at the lowest edge of which 

 a strong upcurved hook originates which is directed more forward 

 than in eucKenor. The presence of dark hairs on the occiput on 

 each side of the center above seems to distinguish the species from 

 vulgaris.
