have the membranous parts of the elytra silvery-white with a 

 short, dark streak at base, sometimes running down to the middle

Neuroctenus pseudonymus Bergroth. 

 Netiroctenus pseudonymus Bergroth, Wien Ent. Zeit., xvm, p. 27, 1898. 



One example, taken at Saluda, N. C., May 20, beneath bark 

 of a decaying chestnut log. This species was originally described 

 from North Carolina. I have taken it twice in the District of 

 Columbia. It is more robust and broader in body than any other 

 of the North American species of Neuroctenus.

Six specimens, males and females, found at Tr-yon, N. C., 

 April 3, 1903, beneath bark of decaying chestnut log. Prof. 

 Herbert Osborn kindly examined one of the male specimens and 

 identified it as N. elongatus, recently described by him from one 

 male specimen in his paper on Aradidae of Ohio.* Having now 

 a series of specimens of both sexes, I give the following descrip 

 tion of the female : 



9- Anterior process of head reaching very slightly over the apex of 

 first antennal joint; process of the antenniferous tubercles acute ; tubercles 

 behind the eves quite prominent. Pronottim twice as wide as its length; 

 posterior margin nearly straight. Dorsal part of abdomen dark brown, 

 with the lateral margin reddish brown, the posterior edges of the segments 

 on the connexivum a little raised near the incisures. Lateral lobes of the 

 genital segment, as seen from above, slightly longer than the middle lobe, 

 which is obtusely rounded and not broader than the lateral lobes. Length 

 5.5 to 6 mm. ; width 2.25 mm. 



Of this species I possess also two examples from Greensburg, 

 Pennsylvania. 



Neuroctenus hopkinsi, n. sp. 



Dark brownish, irregularly granulated. Anterior process of head deeply 

 notched at tip, reaching the apex of the basal antennal joint; process 

 of the antenniferous tubercles verv acute, divaricate; post-ocular part 

 of head rounded, coarsely granulated, not tuberculated laterally. An 

 tennae as long as the posterior margin of pronotum, finely granulated ; the 

 basal joint stout, third joint somewhat more. slender than the others and 

 slightly longer, the fourth fusiform and yellowish at tip with a few 

 long, fine hairs. Pronotum trapezoidal ; the lateral margins slightly 

 sinuated with the anterior angles rounded, somewhat prominent; poster 

 ior margin straight; surface coarsely granulated, a little raised at the an-
