150 MEMOIRS ON THE COLEOPTERA 



apical third, the punctures strong; foveae small, near basal fourth 

 and apical third. Length (cf) 2.9 mm.; width i.o mm. Pennsyl- 

 vania (Franklin Co.; near Lancaster LeConte) . . pedicellatum Lee. 



Form narrower, more elongate, polished, black, the elytra maculate as 

 in the preceding; legs pale brownish-flavate; head relatively larger, 

 only very little narrower than the prothorax, the sulci deep, barely 

 converging; antennae very long and slender, a fourth longer than the 

 elytra, pale brownish-testaceous, infumate near the apex, the medial 

 joints slightly less than three times as long as wide; prothorax much 

 less transverse than in the preceding, only about a fifth to fourth 

 wider than long, similar in general outline, except that the sides an- 

 teriorly are less prominently rounded; base rather less than half the 

 maximum width; elytra fully three-fifths longer than wide, less than 

 two-fifths wider than the prothorax, parallel, with feebly arcuate 

 sides, the oblique base long from the humeri to the pedicel; series of 

 coarse and widely separated punctures not distinctly impressed, 

 obsolete in apical third; foveae as in the preceding; hind tarsi slender, 

 almost as long as the tibiae. Length (cf) 3.0 mm.; width 0.85 mm. 

 District of Columbia strigulosum n. sp. 



Form much more abbreviated, convex, deep black and highly polished; 

 elytra with four small maculae as in the two preceding; legs slender, 

 pale flavate; head but very slightly narrower than the prothorax; 

 sulci very feebly converging as usual, more so on the epistoma than 

 on the front; antennae rather slender, much longer than the elytra, 

 fuscous, becoming testaceous in about basal half, the medial joints 

 feebly obconic, two and one-half times as long as wide; prothorax a 

 fourth wider than long, the sides strongly, evenly rounded anteriorly, 

 very oblique and straighter in basal half to the minute and feebly 

 prominent angles; punctures in the series before the basal beading 

 small; foveae minute; base distinctly less than half the maximum 

 width; elytra short, scarcely one-half longer than wide, almost one- 

 half wider than the prothorax, differing in outline from those of the 

 two preceding in being posteriorly inflated, distinctly wider behind 

 the middle than at base; series of rather strong and moderately sep- 

 arated punctures evidently and coarsely impressed toward the su- 

 ture, but not externally, obsolete near apical third; foveae small, just 

 before basal and at apical third; hind tarsi very slender, only slightly 

 shorter than the tibiae. Length (cf 9 ) 2.7-3.0 mm.; width 0.8- 

 0.92 mm. Missouri (St. Louis) and Illinois (Highland Park). 



fastidiosum n. sp. 



10 Elytra each with a well developed post-humeral pale spot, but with- 

 out trace of a posterior macula 1 1 



Elytra, in the single specimens at hand, without trace of paler macu- 

 lation 12 



ii Body elongate-suboval, convex and shining, the elytra very feebly 

 alutaceous, deep black, excepting the large post-humeral pale macula; 

 legs obscure rufo-testaceous, the femora infumate distally; head but 

 slightly narrower than the prothorax, the sulci evidently converg- 

 ing; antennae longer than the elytra, black, with the basal joint piceo- 

 testaceous, distinctly heavy distally, more slender basally, the medial
