and two short longitudinal lines on either side in front; covered 

 throughout with thin pile, as also are the teeuj^iKi and wings; tegn)ina 

 uniform dark brown, squarely docked at the tip, about twice as long 

 as the pronotuni, the wings dull luteous. Femora rather light brown, 

 covered sparsely with short pile, the tip paler; tibije dirty hiteous, 

 tarsi pale yellowish. Abdomen dark brown, finely and sparsely 

 punctulate, the punctulations giving rise to short, fine golden hairs, 

 which also cover the forceps; sides of the fourth and fifth abdominal 

 segments produced posteriorly to sharp angles, but inconspicuous; 

 the abdomen itself broadens and thickens regularly on the first three 

 or four segments, and then narrows more rapidly, and the sides of 

 the last segment are parallel. Forceps of female straight, simple, 

 attingent, curving inward at tip and pointed, unarmed excepting a 

 slight denticulation on the inner edge. Those of the male resemble in 

 their general direction those of A. arthritica Scudd., but are more 

 strongly bent near the base; at the extreme base the inner edge 

 bears a prominent, rather stout pointed triangidar tooth, and the 

 lower inner edge beyond it is rudely denticulate; the forceps are not 

 dejjressed as in A . arthritica, but trigono-cylindrical, the inner 

 surface flat; but at the tip, which does not diminish in size, they 

 become flattened, and terminate in a nearly straight edge, those of 

 the opposite arms meeting ; either end of the blade developing a' 

 pointed tooth, the preapical one small and bifid, the apical rather 

 long and incurved. Length of body, 10.5-13 mm; of antennas, II 

 mm.; of tegmina and wings, 4.5 mm.: of hind femora, 4 mm.; of 

 forceps, d, 4.5 mm., 9, 3.1 mm. Described from 5 cf, 1 V, taken by 

 Sumichrast (No. 4) in Puebla, Mexico (terra frigida) in January.

 antennas dark luteous, the latter 11-12 jointed; head smooth, full, 

 devoid of impressions. Pronotum subquadrate, scarcely as long as

 the pronotum, docked with a slight obliquity ; wings wanting. Legs'
