and very feebly arcuate from base to apex; basal angles right but 

 obtusely blunt; apex broadly sinuato-truncate, with broadly rounded, 

 unadvanced angles, fully four- fifths as wide as the base; posterior 

 transverse impression obvious, the other obsolete; foveal region 

 with small scattered punctures; inner fovea short, linear, not near 

 the base, the outer deeper, oblique; elytra a third longer than wide, 

 very slightly wider than the prothorax, obtusely ogival behind, the 

 parallel sides feebly arcuate; base not quite as wide as the thoracic 

 base; striae fine, impunctate, evidently impressed, the scutellar mod- 

 erate, oblique, not free; lateral series narrowly or indecisively inter- 

 rupted; intervals broadly convex near the suture. Length (9) 7.4 

 mm.; width 3.5 mm. North Carolina (Southern Pines), Manee. 



pinorum n. sp. 



Sides -of the pronotum rather abruptly and steeply convexo-declivous 

 throughout the length, without trace of depression or gradual de- 

 clivity 13 



13 Prothorax widest at or very close to the base 14 



Prothorax widest at about the middle, subevenly arcuate almost as in 



some species of Bradytus 17 



14 Body deep black or very nearly black above 15 



Body not black 16 



15 Form oblong-suboval, very convex, shining, the elytra micro-retic- 

 ulate; margins of the pronotum feebly diaphanous; under surface 

 shining, black; legs obscure rufous, the femora blackish; head but 

 slightly more than half as wide as the prothorax, with prominent 

 eyes, the strioles long, deep and oblique; antennae dark ferruginous, 

 long, extending well behind the thoracic base; prothorax nearly three- 

 fifths wider than long; apex only two-thirds as wide as the base, 

 feebly sinuate, the angles broadly blunt; sides broadly arcuate, more 

 so anteriorly, subparallel in about basal half, curving inward for a 

 short distance at base to the obtuse angles, finely reflexed; trans- 

 verse impressions subobsolete; foveal region with some moderate 

 sparse punctures; stria fine, biabbreviated; inner fovea long, sharply 

 linear, the outer small, irregularly punctiform, distant from the base; 

 elytra two-fifths longer than wide, obtusely ogival behind, at the 

 middle with the sides nearly straight, curving inward toward base, 

 distinctly wider than the prothorax, the two bases however equal; 

 striae moderately fine, groove-like, slightly impressed, impunctate, 

 the scutellar long, oblique, not free; lateral series distinctly interrup- 

 ted medially; intervals broadly but evidently convex. Male with 

 the middle tibiae coarsely crenate within but hardly at all bent, the 

 abdominal apex with two punctures at each side. Length (o") 7.3 



mm.; width 3.3 mm. Nevada (Reno) nevadica n. sp. 



Form somewhat similar but more abbreviated, black to piceous-black, 

 very convex, shining, the elytra scarcely at all less so in the female; 

 abdomen dark rufous, the legs paler rufous; head rather large, nearly 

 three-fifths as wide as the prothorax and with very prominent but 

 moderate eyes, the oblique strioles somewhat impressed internally; 

 antennae (9) ferruginous throughout, short, barely as long as the 

 thoracic width; prothorax two-thirds wider than long, the sides arcu-
