PHALACRIDJE 6 1 



strigiliform and not very fine, broadly obsolescent basally; pro- 

 sternal process with about five long bristles; metasternal process not 

 as wide as usual. Male with a moderate sinus at the apex of the 

 fifth ventral, about a fourth as wide as the base of the segment, the 

 third segment perfectly simple at apex. Length 1.6-1.7 mm.; 

 width 1.051.1 mm. Iowa (Iowa City) and New York (Catskill 

 Mts.), Wickham and H. H. Smith. Three examples. 



finitimus n. sp. 



Form rather less broadly oval and more convex, smaller in size, polished, 

 black above, the elytra gradually pallescent at tip, apparently in 

 great part from diaphaneity; under surface and legs pale; head 

 nearly half as wide as the prothorax, the antennae long and slender, 

 the club slender; prothorax nearly as in the preceding; elytra dis- 

 tinctly longer than wide, more narrowed toward tip and with im- 

 pressed lines, the punctures everywhere very minute, distant in the 

 series, not or scarcely more distinct internally; micro-reticulation 

 not very fine, substrigilate and very variable in extent, though 

 always obsolescent basally, the stria moderately coarse and impressed ; 

 all the punctures, as in most of the species, bear each a very slender 

 short decumbent hair; prosternal process with about five long bristles, 

 the metasternal process normally wide. Male with abdominal 

 characters as in viduus, the spiculose tooth of the third ventral 

 small but distinct, the sinus of the fifth rather wide but shallow. 

 Length 1.3-1.45 mm.; width 0.9-1.0 mm. Iowa (Iowa City), 

 Illinois (Highland Park) and Minnesota (Duluth). Abundant. 

 Thirteen examples, very even in size obscurus Csy. 



Form very short, broadly elliptic, obtuse behind, very convex, shining, 

 deep black above, only feebly pallescent at tip, the under surface 

 and legs testaceous-brown; head much less than half as wide as the 

 prothorax, the minute sparse punctures obsolescent; antennae very 

 slender in the shaft, of the usual structure; prothorax short, much 

 more than twice as wide as long, the strongly converging sides evenly 

 and moderately arcuate; base finely and feebly margined medially; 

 scutellum but little wider than long, its wavy strigilation rather 

 coarse; elytra scarcely as long as wide, twice as long as the pro- 

 thorax, rounded at the sides, rather rapidly rounding though the 

 obtuse apex, the entire surface covered with a transverse wavy 

 strigilation, which is much finer and more close-set than in the pre- 

 ceding forms but so feeble as to produce scarcely any visible effect 

 in the lustre, the impressed lines very fine and almost obsolete, the 

 subsutural stria unusually fine and scarcely at all impressed, more so 

 posteriorly; the usual serial punctures are everywhere so excessively 

 minute as to be invisible except under high power, but the minute 

 decumbent hairs are evident. Male with a small and rather deep 

 sinus at the apex of the fifth ventral and completely filled with mem- 

 brane, the third segment simple at apex. Length 1.28 mm.; width 

 0.9 mm. Rhode Island (Boston Neck). A single specimen. 



sphaericulus n. sp. 



16 Body rather broadly oval, moderately obtuse behind, small in size, 

 dark piceous in color, the pronotum toward the sides and the elytra
