slightly more than right but minutely subprominent; sides broadly 

 reflexed as in the preceding; elytra elongate, two-thirds longer than 

 wide, two-fifths wider than the prothorax, the five striae rather less 

 deeply impressed than in vnhum and less coarse, the punctures less 

 concealed and more evident, though but little coarser. Male with 

 the anterior tarsi rather long, feebly and gradually tapering, the 

 basal joint longer than wide, much less than twice as wide as the 

 second and with the inner angle of both prolonged; fifth joint dis- 

 tinctly longer than the three preceding. Length (d 71 ) 4.5-5.3 mm.; 

 width 1.7-1.75 mm. New Jersey (Oak Ridge), Shoemaker. 



fiUcorne n. sp. 



Body always distinctly convex, though moderately as a rule 19 



19 Upper surface wholly black, non-metallic and polished; under sur- 

 face more piceous black, the legs dark rufous. Head well developed, 

 with unusually prominent eyes, fully four-fifths as wide as the pro- 

 thorax and even somewhat wider than an elytron, the sulci broad, 

 deep and shining; antennae three-fourths as long as the elytra, 

 blackish, dark rufous at base, the medial joints not quite three times 

 as long as wide, obconic; prothorax rather more than one-half wider 

 than long, the sides almost evenly arcuate from the very blunt apical 

 to the basal angles, the latter obtuse but sharp and minutely prom- 

 inent; margins well reflexed basally, very finely apically; surface as 

 in the preceding but more convex, the stria not entire, the trans- 

 verse impressions fine and feeble and broad and shallow respectively 

 near apex and base; elytra fully one-half longer than wide, two-fifths 

 wider than the prothorax, in form nearly as in v id sum but narrower 

 and more convex, the striae moderately impressed and punctate, the 

 seventh wanting, the sixth distinct as usual basally but obso- 

 lescent posteriorly; foveae similarly near two-fifths and three-fourths. 

 Length (cf 9) 4.4-5.4 mm.; width 1.6-2.0 mm. Pennsylvania (X.

Upper surface not wholly black, the elytra always with pale areas. . . . 20 



20 Elytra black, frequently pallescent at base, or with this pale area 



limited to a small spot at the base of each; subapically, there is 



always a nubilous bioblique pale fascia 21 



Elytra in great part pale, with more or less definite broad median dark 



fascia 22 



21 Legs very pale, uniform testaceous throughout. Body oblong, mod- 

 erately convex, shining, greenish-black; under surface black, the 

 abdomen often partially rufous; head moderate, three-fourths as 

 wide as the prothorax and much narrower than an elytron, the sulci 

 wide, deep and shining, the eyes notably prominent; antennae piceo- 

 rufous, paler basally, long and slender, four-fifths as long as the 

 elytra, the medial joints between three and four times as long as 

 wide; prothorax a third wider than long, the sides broadly rounded, 

 oblique basally, becoming broadly, very feebly sinuate toward the 

 angles, which are obtuse though sharply subprominent; surface 

 punctulate basally, the foveae small, deep, oval^the carina very fine;
