very pale; head more than three-fourths as wide as the prothorax 

 but not as wide as an elytron, the sulci narrow and sharply impressed, 

 rather deep; antennae fusco-testaceous, the middle joints as in con- 

 st rict it HI; prothorax much smaller, the sides more evenly rounded to 

 the very small distinct basal sinus, the angles right, prominent and 

 sharp, the base arcuate, nearly three-fourths the maximum width; 

 surface nearly as in constrictnm, the foveae and carina even smaller 

 but distinct; elytra one-half longer than wide, two-fifths wider than 

 the prothorax, obtusely ogival at tip, the striae rather fine, unim- 

 pressed, the punctures distinct, rather close-set, obsolete at the de- 

 clivity; foveae near two and four sevenths. Length (cf 9) 3.7-4.1 

 mm.; width 1.4-1.65 mm. Xew Jersey and Delaware. Eleven 

 examples acticola Csy. 



Form suboval, moderately convex, shining, the anterior parts feebly 

 alutaceous, feebly subaeneous above; elytra not very intense black, 

 each with a minute pale point on the basal declivity, very faint 

 streaks on intervals eight to five near anterior third, the outermost 

 long, and an oblique paler fascia near apical third, composed of 

 lines on the five outer intervals, not coalescing with the distinct 

 apical pale spot; under surface black, the abdomen slightly pices- 

 cent, the legs dark rufous; head less than three-fourths as wide as 

 the prothorax, the sulci sharply defined, narrow and deep, parallel; 

 antennae slender, piceous, paler at base, the medial joints very nearly 

 three times as long as wide; prothorax one-half wider than long, 

 only slightly narrowed at base, which is but little narrower than the 

 apex and fully three-fourths the maximum width; sides rather 

 strongly, subevenly rounded, becoming gradually broadly but dis- 

 tinctly sinuate basally, the angles right; anterior impression obso- 

 lescent, the posterior feeble and narrow but evident, the stria very 

 fine; foveae rather large, impressed, long, deep and linear axially, the 

 carina shorter and fine but distinct; elytra one-half longer than wide, 

 two-fifths wider than the prothorax, subcircular at tip; striae rather 

 fine, barely at all impressed, obsolescent near the apex, the punc- 

 tures very fine, moderately close, larger and more distinct basally; 

 foveae near two and four sevenths. Length (cf) 3-5 mm.; width 

 1.33 mm. New Jersey (near the Delaware River). . . . editum n. sp. 



65 Body in its inflated elytra and more convex form resembling the 

 preceding subsection; the elytral striae, though entire, are, on the 

 declivity more sloping than in the following species fine but sim- 

 ply impressed and not groove-like. Rather small, greenish-black, 

 shining, alutaceous anteriorly; elytra each with a small pale spot 

 on the basal slope, also a broad external posterior spot curving 

 about the apex, subequally wide throughout and well defined; under 

 surface black, the abdomen partially rufous; epipleura dull rufous, 

 their inner margin black; legs clear and pale rufous throughout; 

 head large, with very prominent eyes, about as wide as the prothorax, 

 the sulci rather feeble; antennae very slender, fusco-testaceous, the 

 medial joints not quite three times as long as wide; prothorax one- 

 half wider than long, the base not much narrowed, three-fourths 

 the maximum width; sides evenly, rather strongly rounded, becom-
