Rhode Island (Boston Neck). 



Allied to capillosulum, but much narrower and less ventrlcose 

 and differing in coloration. The blackish elytra with pale an- 

 terior parts is a form of coloration which is very rare in the 

 genus, and known to me otherwise only in nigripenne, which does 

 not belong to this division. Limatum is represented before me 

 by a single female example. 



82. C. pumiluiu n. sp. — Moderately stout and but slightly ventrlcose, 

 polished and impunctate, piceous-black, the elytra rufo-testaceous, legs and 

 antennae pale rufous; pubescence abundant, coarse, pale, rather short and 

 recurved but without longer setae on the elytra. Read slightly wider than 

 long, broadly subcircular behind, the eyes only moderate in size and not very 

 prominent; front feebly concave; clypeus perfectly even and transversely recti- 

 linear at apex. Antennse nearly 3^ as long as the body, slender, the club nar- 

 row but incrassate and somewhat abruptly formed ; second joint obconic, }£ 

 longer than wide, as long as the next two and much thicker; three to six equal 

 in width and smooth, the seventh and following rougher; eighth to eleventh 

 paler in color; third and sixth subequal and about as long as wide; fourth and 

 fifth nearly equal and just visibly longer; seventh just visibly thicker, nearly 

 as long as wide; eighth fully % wider than the seventh, only slightly nar- 

 rowed at base, fully as long as wide ; ninth 34 ^^^ tenth nearly 3^ wider than 

 the eighth, }'^ and % wider than long respectively; eleventh distinctly stouter, 

 obliquely pointed in ogive, about as long as the two preceding. Prothorax 

 rather well developed but not as long as wide, conic with the sides broadly 

 arcuate; apex a little more than % as wide as the base, which is scarcely more 

 than }4, wider than the head ; surface strongly biimpressed transversely near 

 the base. Elytra but slightly more than }^ longer than wide, much more 

 than twice as long as the prothorax and about % wider, widest but slightly 

 before the middle, the sides broadly arcuate; apex acutely rounded; humeral 

 plica moderate in length, strong and distinct, the adjacent impression deep 

 and rather conspicuous; fovese deep; subsutural impressions strong, the suture 

 vfith a distinct bead which is expanded at base. Abdomen with the basal 

 segment broadly arcuate at apex, overlapping the next and fringed with 

 coarse porrect and separated hairs. Legs moderate, the anterior femora very 

 strongly, the four posterior much less strongly, clavate; tarsi rather short and 

 somewhat compressed, the basal joint of the posterior distinctly shorter than 

 the next two combined. Length 0.9 mm. ; width 0.4 mm. 



New York (Hudson Yalley); Canada (Ottawa); Iowa (Iowa 

 City). 



This species may be recognized at once in the present group 

 by its very small size, and unusualh^ short basal joint of the hind 

 tarsi. The terminal spur of the hind tibiae in the male is very 

 slender but nearly straight, and is scarcely a third as long as the 

 tarsus. Several specimens.
