408 MEMOIRS ON THE COLEOPTERA 



pression notably feeble, the posterior more distinct, the stria rather 

 deep, subentire; foveae small and narrow, deep, at lateral fourth; 

 elytra two-fifths (cT) to one-half (9) wider than the prothorax, 

 parallel, with evenly arcuate sides, subcircularly rounded at apex; 

 striae moderately coarse, impressed and distinctly punctate inwardly, 

 becoming feeble though easily traceable laterally; dorsal punctures 

 notably coarse. Length (c? 9 ) 3.8-4.0 mm.; width 1.35-1.45 mm. 

 Rhode Island (Boston Neck) rhodensis n. sp. 



Form nearly as in the preceding but with distinctly smaller prothorax, 

 the eyes not so small and rather more prominent; head nearly three- 

 fourths as wide as the prothorax, somewhat elongate, rufescent at 

 base and apex, the sulci subinterrupted; antennae dark rufous, a 

 little longer and thicker than in rhodensis and more evidently in- 

 crassulate distally, less evidently shorter than the elytra; prothorax 

 one-half wider than long, the basal angles obtuse, sharp but not 

 prominent; anterior impression subobsolete, the posterior distinct; 

 fovese much larger, relatively shallower and less definitely limited 

 than in the preceding species; elytra not quite one-half longer than 

 wide, almost one-half wider than the prothorax, feebly inflated pos- 

 teriorly, circularly rounded behind; striae as in rhodensis, the dorsal 

 punctures coarse. Length (cf) 4.2 mm.; width 1.48 mm. Labra- 

 dor (W. St. Modest), Sherman brumalis n. sp. 



8 Elytra each with the normal three discal punctures 9 



Elytra each with but two discal punctures, the median constantly want- 

 ing - 14 



9 Elytra more nearly of the form prevailing in the preceding group, 

 being oblong-oval. Body piceous-black, moderately convex, shin- 

 ing, the legs rufous; head not longer than wide, fully four-fifths as 

 wide as the prothorax, the eyes moderately large but only slightly 

 prominent; sulci coarse and deep, entire; last palpal joint not as 

 long as the third; antennae filiform though not very slender, piceous, 

 rufescent basally, distinctly shorter than the elytra; neck rufescent; 

 prothorax two-fifths wider than long, the base and apex subequal 

 in width; basal angles reflexed, obtuse, the tips not prominent; an- 

 terior and posterior impressions both distinct, the stria subentire; 

 foveae deep, slightly outside of lateral fourth; elytra one-half longer 

 than wide, one-half to two-thirds wider than the prothorax, rather 

 obtusely but evenly, subcircularly rounded at apex, the sides some- 

 what strongly, evenly arcuate; striae moderate, not clearly punctate, 

 feebly impressed inwardly, gradually obsolete laterally, the dorsal 

 punctures very moderate in size. Length (cf 9 ) 4.4-4.6 mm.; width 

 1.7-1.75 mm. Colorado. Levette collection . saxatilis n. sp. 



Elytra more subglobose, less elongate and more convex, the striation 

 much less developed 10 



10 Elytra with the medial puncture slightly behind the middle of the 

 length as usual, the striae very fine but rather sharply impressed 

 suturally 1 1 



Elytra with the medial puncture before the middle of the length, the 

 striae usually indefinite, very fine when visible 13 



II Antennae notably long, very slender and filiform, fully as long as
