312 MEMOIRS ON THE COLEOPTERA 



prothorax having the triangle of black spots as in the preceding but 

 in shape more as in dentatus, the sides straight and oblique from the 

 apex of the large triangular tooth to near the apex, more oblique 

 but straight behind; femora strongly, abruptly clavate. Length 

 ( 9 ) 6.0 mm. ; width 2.0 mm. District of Columbia. . testaceus n. sp. 



Elytra with the three discal threads obsolescent, though generally trace- 

 able; sides of the prothorax with a more or less developed minute 

 abrupt denticle as in punctatus 7 



7 Antennal scape unusually thick, elongate-oval, scarcely four times 

 as long as wide. Body moderately slender and convex, obscure 

 testaceous, the cinereous vestiture longer and coarser than usual, 

 almost concealing the sculpture though not dense; antennae (9) 

 pale, mottled, three-fourths longer than the body; prothorax dull, 

 nearly twice as wide as long, with the usual three dusky but not 

 at all tuberculiform spots; elytra rather more than twice as long 

 as wide, parallel, evenly arcuato-convergent at the sides posteriorly 

 to the very narrow and oblique sinuate apical truncatures; surface 

 deeply but not coarsely punctate, the punctures separated by fully 

 their own widths, the lateral black cloud extending inwardly to 

 outer fourth; oblique fascia composed of a few black spots; black 

 clusters few in number but distinct; femora strongly and abruptly 

 clavate. Length (9) 6.2 mm.; width 2.2 mm. Indiana. 



scapalis n. sp. 



Antennal scape more slender, more than four times as long as wide. . .8 



8 Oblique elytral fasciae composed each of three elongate black spots. 

 Body dark brown in color, rather densely clothed with small dusky- 

 cinereous hairs, with the small black points on the three feeble 

 elytral threads very sparse but evident, the lateral black cloud 

 confined to the flanks; prothorax less than twice as wide as long, 

 densely dull, the three blackish spots somewhat convex; elytra 

 formed as in the preceding but narrower, similarly punctured; 

 abdomen fuscous, sometimes partially rufescent; hind femora (9) 

 unusually feebly clavate for this section though distinctly so. 

 Length (cf 1 9 ) 5.0-5.5 mm.; width 1.8 mm. New Jersey and 

 New York (Lake Champlain). A male from Indiana seems to be 

 conspecific; it has all the femora strongly clavate. . .vicinus Hald. 



Oblique elytral fasciae continuous or partially so, not clearly composed 

 of spots 9 



9 Body unusually short and convex for this division of the genus, pale 

 testaceous, the elytra barely twice as long as wide; pubescence 

 minute, moderately dense, cinereous or yellowish; antennae moder- 

 ate; prothorax distinctly less than twice as wide as long, the three 

 blackish spots very ill-defined; elytra more distinctly exceeding 

 the prothorax in width than in any of the three preceding except 

 testaceus, rounding behind to the oblique sinuous apices, the black 

 lateral cloud extending inwardly some distance and distinct, the 

 elevated lines obsolete, the fasciculi very few in number; femora 

 strongly clavate in both sexes. Length (cf 9 ) 4.0-5.2 mm.; 

 width 1.4-1.9 mm. District of Columbia and Delaware.
