tilinear. Antennae slender, longer than the head and prothorax, the club nar- 

 row but somewhat abrupt in formation ; second joint subcylindric, ^5 longer 

 than wide, rather longer than the next two and distinctly thicker; three to 

 six equal in width, smooth and cylindric; three, four and six equal and very 

 nearly as long as wide ; fifth a little longer than wide ; seventh scarcely more 

 than 34 wider than the sixth and but little longer, not quite as long as 

 wide ; eighth full % 'wider than the seventh, nearly as long as wide, conic 

 at apex ; ninth and tenth subequal, I4 wider than the eighth, about ^^ 

 wider than long ; eleventh decidedly thicker, fully as long as the two pre- 

 ceding, obliquely pointed in ogive at apex. Prothorax narrow, fully as long 

 as wide, parallel and feebly arcuate at the sides in basal half, then gradually 

 and arcuately narrowed to the apex, which is fully 3/| ^s wide as the base, the 

 latter ^4 wider than the head ; surface finely and transversely biimpressed 

 near the basal margin. Elytra nearly -5 longer than wide, barely twice as 

 long as the prothorax and ^5 wider, widest before the middle, the sides evenly 

 arcuate ; humeral plica narrow but long and strong, the subhumeral impres- 

 sion rather narrow but deep ; inner fovea somewhat distinct ; subsutural im- 

 pressions narrow but evident, the suture only very narrowly and feebly 

 beaded basally , the bead not expanded at base. Legs as usual ; anterior femora 

 distinctly, the four posterior more feebly, clavate. Length 0.9 mm. ; width. 

 0.35 mm. 



Rhode Island (Boston Neck). 



A very small but peculiar species, which may be identified by 

 the narrow and subparallel prothorax, this being apparently 

 longer than wide. A single specimen of undetermined sex. 



54. C. parcum n. sp. — Narrowly suboval, highly polished and impunc- 

 tate, black, the elytra dark rufous, blackish posteriorly; prothorax slightly 

 pale at apex; legs and antennae pale testaceous; pubescence not very abundant, 

 rather coarse, long, feebly curved, suberect and decidedly. sparse on the elytra, 

 but pale in color and distinct. Head moderately developed, distinctly wider 

 than long, subparabolic behind the eyes, which are small and inconspicuous 

 although somewhat convex; depression between the antennal prominences 

 rather strong; clypeus not at all carinate, the apex perfectly even, transverse 

 and rectilinear. Antennie somewhat longer than the head and prothorax, 

 moderately stout, the club rather feeble, somewhat gradual in formation; 

 second joint but slightly thinner than the first, cylindric, as long as the next 

 two and much thicker, % longer than wide; three to six equal in width; third 

 nearly as long as wide; fourth and sixth just visibly shorter; fifth fully as long 

 as wide; seventh only }4: wider than the sixth, a little wider than long; eighth 

 % wider than the seventh, slightly wider than long, broadly rounded only at 

 apex; ninth 3^ wider than the eighth, scarcely 34 wider than long; tenth sub- 

 equal in width but more transverse, % wider than long; eleventh elongate, 

 scarcely thicker, as long as the two preceding, gradually acutely and obliquely 

 pointed. Prothorax very feebly conic, nearly as long as wide, with the sides 

 broadly arcuate ; apex % as wide as the base, the latter scarcely 34 wider than
