328 MEMOIRS ON THE COLEOPTERA 



joint not black but only slightly browner, two and one-half times 

 as long as the body (cf ), or but little more than twice as long (9 ); 

 prothorax less transverse, otherwise nearly similar, except that the 

 spicules are much less minute and the sides before them less oblique, 

 the spots small, feebler and brownish; elytra broader, two-thirds 

 to three-fourths longer than wide, otherwise similar, except that the 

 punctures are rather closer, the pale lines less distinct and the spots 

 smaller, the posterior larger, broadly truncated at the carina, the 

 apical angles dentiform, not very acute; flanks in great part blackish, 

 coarsely, very deeply and densely punctate; under surface rufous, 

 the femora rather strongly clavate, only a little less so in the female, 

 the posterior ( 9 ) distinctly clavate though rather gradually so and 

 much less abruptly than in cry plica; fifth ventral (cf ) longer than 

 the fourth, the apical truncature much broader than in the preceding. 

 Length (cf 9 ) 4.5-5.6 mm.; width 1.4-2.0 mm. District of Colum 

 bia and Indiana variolata n. sp. 



Form nearly similar but blackish, the elytra feebly rufescent, the under 

 surface wholly deep black; legs black, the tibiae palish basally, the 

 femora feebly rufescent toward base; vestiture as in the preceding, 

 cinereous-white; head smaller, nearly as in cryptica, indented and 

 striate; antennae similar but with darker scape, not quite so long 

 as in variolata; prothorax nearly similar but much more distinctly 

 exceeding the head in width; elytra nearly similar but flatter and 

 with the carina along the line of flexure very strong, sometimes 

 prominent, the two denser whitish lines distinct; punctures rather 

 strong and close-set, the black spots and posterior macula as in 

 variolata; flanks blackish throughout, very closely and strongly 

 punctate; femora rather strongly clavate; fifth ventral (cf ) nearly 

 as in cryptica. Length (cf) 4.0-5.5 mm.; width 1.7-2.0 mm. 

 Maine (Monmouth), C. A. Frost frigida n. sp. 



12 Form oblong, moderately stout, depressed, the lateral elytral carina 

 fine and prominently elevated; color blackish, the elytra piceous 

 throughout; pubescence close, minute, fusco-cinereous; under surface 

 and legs black, the femora rufo-piceous at base; head indented, 

 opaque; antennae (9 ) almost twice as long as the body, infuscate, 

 the scape black; prothorax twice as wide as long, prominently 

 rounded medially at the sides, which are thence oblique to apex and 

 base, the sides of the apex swollen; spicule straight, acute, pro- 

 jecting perpendicularly from the oblique side at basal fifth; surface 

 finely, rather closely punctate, dull, the median dark spots well 

 developed but not tumid; elytra twice as long as wide, parallel, 

 arcuately oblique posteriorly, dehiscent at apex, the external angle 

 dentiform; surface with moderate and well spaced punctures and 

 very small scattered spots of black, the posterior macula large, 

 oval, truncated by the carina; two discal paler and denser lines 

 evident; flanks closely pubescent; strongly, rather closely punctate; 

 hind femora distinctly clavate apically though rather slender. 

 Length (9 ) 6.0 mm.; width 2.0 mm. New York, .binocularis n. sp.

 moderately densely with fine fusco-cinereous pubescence; under
