ClCINDELID/E AND CARABIDyE 17 1 



rounded and continuous with the sides, the position of the angles 

 marked by the usual strong setigerous puncture; surface broadly 

 convex, with distinct median stria, the finely reflexed sides 

 scarcely at all paler in color, the basal impressions broader, more 

 indefinite and more oblique than in the preceding; apex about as 

 wide as the base, feebly sinuate, the angles blunt but not so broadly 

 rounded as in parmatus; elytra more oblong, a fourth longer than 

 wide, the sides broadly arcuate and rather moie broadly reflexed, 

 fully two-thirds wider than the prothorax, the striae extremely fine, 

 impunctate, almost obsolete externally, the intervals flat, the third 

 with the usual three punctures; apices rather broadly arcuato- 

 subtruncate and without trace of sinuations; surface lustre feebly 

 opalescent; scutellar fovea distinct; tarsi extremely slender, the 

 posterior much more notably shorter than the tibiae than in the 

 preceding. Length (9) 4.6 mm.; width 1.9 mm. Rhode Island. 



filicornis n. sp. 



6 Form rather narrow and shining, moderately convex, piceous, the 

 elytra but faintly variegated; head rather wider than long, two- 

 thirds as wide as the prothorax, the eyes large, moderately promi- 

 nent; antennae slender, three-fifths as long as the body, the outer 

 joints gradually shorter, the tenth two and one-half times as long 

 as wide and three-fourths as long as the third; prothorax one-half 

 wider than long, evenly rounded at the sides, the base broadly 

 arcuate, truncate or subsinuate medially, as wide as the apex, which 

 is feebly sinuate; basal angles very broadly obtuse and rounded; 

 surface moderately convex, finely reflexed at the sides, feebly 

 striate, the impressions very small, rounded and basal; elytra oblong, 

 fully a fourth longer than wide, two-fifths wider than the prothorax, 

 the sides parallel and broadly arcuate, the combined apices almost 

 evenly rounded; surface and striae almost as in the preceding, except 

 that there is no evident opalescence; legs and tarsi extremely slender, 

 the posterior tarsi much shorter than the tibiae. Length (cf ) 3.5 mm. ; 

 width 1.4 mm. Louisiana (Alexandria). A single rather immature 

 example pusio n. sp. 



Form nearly similar, shining, piceous-black, the pronotum feebly pal- 

 lescent toward the periphery, the elytra colored almost as in par- 

 matus, but with the short transverse pale sutural spot more posterior 

 in position and evidently behind the middle; under surface rufo- 

 piceous, the legs pale; head as long as wide, with well developed eyes, 

 three-fifths as wide as the prothorax; antennae scarcely more than 

 half as long as the body, less slender than usual, the joints much 

 shorter, gradually decreasing, the tenth about twice as long as wide; 

 prothorax three-fifths wider than long, the sides rounded and with a 

 fine reflexed margin, the general outline of the sides and base as in 

 parmatus, the impressions very small, foveiform and very near the 

 basal marginal bead, which is broadly interrupted medially; elytra 

 a fourth longer than wide and nearly a third wider than the pro- 

 thorax, throughout nearly as in parmatus; tarsi unusually short, the 

 posterior scarcely more than two-thirds as long as the tibiae. Length 

 ( 9 ) 3.7 mm.: width 1.4 mm. Illinois brevicornis n. sp.
