towards the tip; third segment sHghtly curved, sHghtly enlarged towards 

 the apex, moderately clothed with rather long decumbent hairs; apical 

 segment subconical, beset with long straight hairs and dense pile, at its 

 widest part about three-fourths as broad as the apex of the third. 

 Pronotum widely pitted, tricarinate, the carinte not as strongly raised 

 as in brevicornis or grossocerata, the lateral carinse without distinct areolee; 

 lateral margins reflected back against the sides of the pronotum, with a 

 single series of areolee. Sides of thorax widely pitted. Elytra strongly 

 convex, reaching a little beyond the abdomen; costal area with a single 

 row of areolee; discoidal, sutural, and subcostal areas without a trace 

 of a boundary. Length, 2.51 mm.; width, 1.10 mm. 



Color: General color dark grayish-brown, the areolae whitish. 

 Rostral laminte whitish. This species like the other two known species 

 in the genus has a very shining appearance, due to the polished nervures. 



Described from a macropterous male, taken at Ames, 

 Iowa, June 14, 1897, by the senior author. It is closely related 

 to A. grossocerata, but readily differentiated from it by the 

 characters given in the key.

This species, described in Ohio Biol. Survey Bulletin, No. 8, p. 245, 

 has been seen so far only from Maine and New Hampshire. The figure 

 shows the third antennal segment slightly too thick in the middle 

 portion and the basal process is large and formed as in related genera. 

 This difference may be noted by a comparison of the figtire with the 

 photograph of the type presented herewith.
