and narrower than the base, the foveae linear, rather shallow, with 

 fine dispersed feeble punctures; elytra much more convex than 

 usual, oblong-oval, rather short, one-half longer than wide, barely 

 three times as long as the prothorax and, at the middle of the arcuate 

 sides, a fourth wider; sinus extremely feeble, barely traceable; 

 striae fine but well impressed, the scutellar long and oblique, the 

 intervals bioadly though evidently convex, the third with a fine 

 puncture near apical third, touching the second stria; abdomen with 

 the basal punctures extremely fine, sparse and scarcely traceable; 

 met-episternum opaque but impunctate; hind tarsi (9) with the 

 first joint scarcely visibly shorter than the next two combined, 

 smooth above like the others and nearly one-half longer than the 

 fifth. Length (9) 12.7 mm.; width 5.2 mm. New Hampshire. 



solutus n. sp. 



Form narrower, more elongate and less convex, deep black throughout, 

 the legs black; antennae dark brown, the two basal joints nearly 

 black; head not quite three-fourths as wide as the prothorax, the 

 eyes smaller than in solutus; frontal foveae minute, rounded, per- 

 forato-punctiform; prothorax as in the preceding throughout and 

 with the marginal gutter very fine anteriorly, much less transverse, 

 however, being barely two-fifths wider than long, the basal margin 

 narrowly interrupted medially and the fovese slightly more elongate; 

 elytra oblong-oval, rather convex but less so than in solutus, not 

 quite one-half longer than wide and only barely visibly wider than 

 the prothorax, the sides broadly rounded; apex gradually ogival, 

 the sinus feeble though evident; striae notably fine, barely impressed, 

 the intervals nearly flat, the third with a small feeble puncture 

 attached to the second stria; surface uniformly opaculate; abdomen 

 with a few very fine punctures medially at base, the met-episterna 

 opaque and with a few punctures near the inner angle; mentum 

 tooth distinct as in the preceding; hind tarsi nearly similar. Length 



(9) 13.8 mm. width 5.0 mm. New Jersey providens n. sp. 



Form parallel (cf) or with the hind body feebly inflated and more convex 

 (9 ), black, polished, the under surface and legs black or nearly so, 

 the tarsi of the two anterior pairs piceo-testaceous as usual; antennae 

 and palpi testaceous throughout; head large, especially in the female, 

 three-fourths as wide as the prothorax, the eyes moderately promi- 

 nent, the foveae very small, perforate; antennae (c?) scarcely extend- 

 ing to the thoracic base; prothorax two-fifths wider than long, paral- 

 lel, rounding anteriorly, the apex slightly narrower than the base; 

 surface as in the two preceding, except that the portion between the 

 foveae and the sides is still more convex, also impunctate, the foveae 

 linear but more broadly impressed and sparsely punctate, the basal 

 margin interrupted at the middle; elytra (cf ) one-half longer than 

 wide, not at all wider than the prothorax and moderately convex, 

 or ( 9 ) only a third longer than wide.felightly wider than the prothorax 

 and barely two and one-half times as long and strongly convex, 

 obtusely ogival at apex, the sutural angles dentate (9), the sinus 

 extremely feeble; striae moderate, deeply impressed and with convex 

 intervals (c?), or scarcely impressed and with nearly flat intervals,
