OF WASHINGTON. 165 



the antenniferous tubercles acute and curved ; part behind the eyes ob 

 tusely rounded, edged with a few fine granules; tubercles laterally obso 

 lete. Antennae not quite twice the length of head ; basal joint very stout, 

 broader than the frontal part of head; second joint oval like the basal 

 one, but much smaller and not thicker than the two remaining joints, 

 which are cylindrically formed; third joint nearly equal in length to the 

 first; the terminal one a little longer than the third and second together, 

 covered with fine hairs. Pronotum half as long as wide with a transverse 

 furrow before the middle; the lateral margins anteriorly slightly sinuate; 

 surface very finely granulate, posteriorly rugulose. Scutellum nearly as 

 long as broad, having also the same length as the pronotum in the mid 

 dle, more coarsely granulated with a short, faint carina anteriorly. The 

 membranous part of elytra rugose and densely granulated, color black; 

 near the middle of corium runs a transverse, yellowish spot, in some 

 specimens obliterated. The terminal genital segment of male convex and 

 long, but extending barely beyond the genital lobes. 



Length of female 3.8 to 4 mm. ; width i.S mm. 



Length of male 3.6 to 3.8 mm. ; width 1.6 mm. 



Tryon, N. C., May 21, 1903 (W. F. Fiske. three specimens);

This species has some similarity to A. montanus Champion, 

 chiefly in the shape of the antennae, but differs in being smaller 

 and having the post-ocular part of head not spinous. I take 

 pleasure in dedicating it to Mr. W. F. Fiske. 



Mr. Heidemann stated, in this connection, that Prof. Herbert 

 Osborn has in preparation a monograph of the Aradidae, Dr. 

 Hopkins asked Mr. Heidemann what constitutes the food of 

 Aradids. Mr. Heidemann stated that, so far as known, Aradidae 

 appear to feed upon fungi. Dr. Hopkins said that this, also, was 

 his opinion as to their food habits and he did not believe them 

 insectivorous.* Dr. Ashmead stated that certain Proctotrypid 

 parasites belonging to the genus Aradophagus infest the eggs of 

 Aradida3. 



*A previous discussion on this subject is to be found in Proc, Ent. Soc. 

 Wash., iv, No. 4, July 16, 1901, pp. 390 and 391.
