STAPHYLINID/E. 157 



This species differs conspicuously from acutella and simulata in 

 its much more slender antennae and more developed elytra, among 

 other obvious inconsistencies. 



Colpodota sobria n. sp. Small, fusoid, moderately convex, shining, deep 

 black, the elytra dark piceous-brown, the legs pale piceo-flavate ; punctures 

 fine, close and asperate, the abdomen finely punctulate, unusually shining 

 and coarsely but feebly micro-reticulate; head orbicular, nearly as long as 

 wide, the eyes at about two-thirds their length from the base, the tempora 

 arcuately converging; antennae moderate in length, rather slender and feebly 

 incrassate, black, the basal joint longer than either of the next two, which 

 are equal, the fourth obtrapezoidal and a little wider than long, the outer 

 joints very moderately transverse, the last as long as the two preceding; 

 prothorax only moderately transverse, convex, subparallel and evenly rounded 

 at the sides, much wider than the head and evidently narrower than the 

 elytra, very obsoletely impressed on the median line behind the middle; 

 elytra rather transverse, with diverging sides, the suture scarcely so long 

 as the prothorax; abdomen at base a little narrower than the elytra, rapidly 

 tapering and with broadly arcuate sides to the moderately acute apex, the 

 fifth tergite very evidently longer than the fourth. Length 1.4 mm.; width 

 0.38 mm. Mississippi (Vicksburg). 



Much smaller than some of the preceding and with the abdomen 

 more shining; also less densely sculptured, with the prothorax 

 smaller than usual and the head relatively a little larger than in 

 the preceding. 



Colpodota turbans n. sp. Elongate-fusiform, somewhat convex and shin- 

 ing, the punctures fine, rather close, dense and strongly asperate on the elytra, 

 which are opaculate; color black, the elytra dark brown, the legs pale; 

 head distinctly wider than long, slightly inflated basally, the eyes at much 

 less than their length from the base but scarcely at all prominent; antennae 

 moderately long, rufo-piceotis, paler basally, thick, gradually and strongly 

 incrassate distally, the first joint longer and much stouter than the second, 

 the latter longer than the third, the fourth transverse, the outer joints dis- 

 tinctly so, the last unusually large, ogivally pointed and very much longer 

 than the two preceding; prothorax very moderately transverse, narrower 

 at apex than at base, the sides strongly arcuate, much wider than the head, 

 wider than the base and about as wide as the apex of the elytra, not evi- 

 dently impressed; elytra rather short, with diverging sides, the suture about 

 three-fourths as long as the prothorax; abdomen gradually tapering and 

 subacute, but little narrower at base than the elytra, the fifth tergite almost 

 as long as the two preceding. Length 1.78 mm.; width 0.4 mm. Texas 

 (Galveston). 



The noticeably heavy and incrassate antennse, with unusually 

 large terminal joint, will render the identification of this species 

 at all times easy.
