have but two rather rare species which may be described as 

 follows : — 



Body rather stout, subparallel, convex, very highly polished, no strlgilation 

 or reticulation being observed at any part of the upper surface, or on the 

 lower surface of the head and abdomen, piceous-black in color, the 

 head rather darker, the elytra very pale, becoming gradually infumate 

 in basal half, the legs and antennae pale; head not longer than wide 

 behind the antennae, suboval, broadening basally, with the sides arcu- 

 ate, the angles rather narrowly rounded; punctures very coarse, deep 

 and raiher close-set toward the sides, broadly wanting along the 

 middle, the post-ocular flat line strongly and closely puuctate In a 

 double line along its middle only, the under surface with a few 

 coarse elongate punctures, impunctate toward base; sutures arcuate, 

 gradually becoming contiguous behind the middle, the space between 

 them finely, very roughly sculptured and almost lustreless; antennae 

 longer than the head, rather slender; prothorax but slightly elongate, 

 about as wide as the liead, the sides moderately converging and obviously 

 arcuate throughout, the anterior angles very broadly rounded; dorsal 

 series of about five, the sublateral of about four, very coarse, irregular 

 and widely spaced punctures; between the latter series and the sides 

 anteriorly there is a very large setigerous puncture; elytra ample, 

 longer and much wider than the prothorax, the punctures of the medial 

 series larger and more close -set than those of the lateral series and 

 separated from the sutural puncturts by a wide sculptureless space; 

 abdomen finely, sparsely punctulate. Length 4.9 mm.; width 0.9 mm. 

 New York (Hudson Valley) cephalicas Lee. 



Body stout, parallel, convex, nearly similar in sculpture to the preceding, 

 black In color, the prothorax bright rufous, the elytra pale fiavo- 

 testaceous, somewhat diaphanous, clouded with black toward the 

 suture, narrowly at apex, gradually more broadly basally and involving 

 the entire width at base; legs pale, the antennae slightly darker, 

 testaceous; head behind the antennae but slightly longer than wide, 

 feebly inflated basally, the sides arcuate, the angles rounded, very 

 brotdly impunctate toward the middle, the punctures very coarse and 

 distinctly close-set laterally, the flattened post- ocular line narrow, 

 closely, confusedly and strongly punctate, becoming smooth near the 

 edges; under surface coarsely, less closely punctate, the lateral grooves 

 as in cephalicus; prothorax larger, nearly a third longer than wide, only 

 very slightly narrower than the head, the converging sides nearly 

 straight, the apical angles broadly rounded; dorsal series of about six 

 punctures, rather smaller than in cephalicus, extending to basal flflh or 

 less, the sublateral series short, of about four punctures; there is also 

 a single isolated puncture between the anterior limit of the latter series 

 and the side margin; elytra rather longer than wide, with slightly 

 diverging straight sides, slightly wider than the prothorax, the suture 

 evidently shorter than the latter, punctured nearly as in cephalicus; 

 abdomen parallel, somewhat narrower than the elytra, punctured nearly 

 as in the preceding. Length 6.0 mm.; width 0.9 mm, Kentucky and 

 Missouri (St. Louis) rubricollis n. sp.
