Elytra at base subequal in width to pronotum behind middle ; sides 

 vaguely expanded posteriorly, separately obtusely rounded at apices ; 

 surface sparsely clothed with short, recumbent, yellowish- white hairs, 

 densely, coarsely punctate, the punctures coarser and deeper on apical 

 declivity, but impunctate along sutural margins behind marginal 

 teeth on declivity ; apical declivity with sutural striae deeply depressed 

 in front of teeth on declivity, the sutural margins broadly expanded 

 and elevated, with two large, round teeth near top of declivity, the 

 teeth slightly divergent and separated at bases, and the lateral margins 

 thickened and strongly elevated; each elytron with two more or 

 less distinct, costiform callosities along lateral margin of apical 

 declivity. 



Abdomen beneath densely, finely punctate, rather densely clothed 

 with short, recumbent, yellowish hairs ; last visible sternite subtruncate 

 at apex, with distinct lateral grooves. 



Female. — Differs from the male in having the last visible abdominal 

 sternite vaguely emarginate at the apex, and the lateral grooves 

 obsolete. 



Length 3-5 mm., width 1-1.6 mm.

 Georgia: Barnesville, May 29, 1933 (T. L. Bissell). 

 Illinois: Southern part (H. Soltau). 

 Indiana: Hammond, May 30, 1915 (C. Selinger). 

 Kansas: Riley County (E. A. Popenoe).

Hosts. — The species has been reared from hickory {Hicoria sp.) 

 and chestnut (C astanea dentata (Marshall) Borkhausen). 



Horn described this species from a single specimen. Lesne (1901) 

 redescribed what he thought to be this species from a single female 

 collected in Texas by Belfrage. This last specimen is not bidentata 

 Horn, but lesnei Fisher. 



Scobicia monticola, new species 



Male. — Brownish black, base of pronotum reddish on each side, 

 antennae and legs, except tarsi, reddish brown, palpi and tarsi brown- 

 ish yellow. 



Head slightly convex, sparsely, rather finely punctate on front and 

 clypeus, with fine, longitudinal, parallel costae on occiput, rather 

 densely clothed on front with very long, erect, yellowish- white hairs, 

 which are shorter and inconspicuous at middle behind clypeus; 

 clypeus flat, deeply depressed at middle along posterior margin; 

 clypeal suture distinct at middle, obsolete at sides. 



Pronotum slightly wider than long, widest behind middle; sides 

 broadly rounded, more strongly converging anteriorly, with three 

 small, broad teeth on each side near apical angle; posterior angles
