STAPHYLINID/E. 163 



breviated, the sides but feebly diverging, the suture nearly a third longer 

 than the prothorax; abdomen slightly narrower than the elytra, rather 

 strongly tapering, with almost straight sides, the fifth tergite less than two- 

 thirds as wide as the first and almost as long as the two preceding. Length 

 1.5 mm.; width 0.37 mm. California (Sta. Clara), Harford. 



To be recognized by the subparallel prothorax, well developed 

 elytra, shorter third antennal joint and other features. 



Colpodota abdicans n. sp. Stout, fusoid, rather convex and somewhat 

 shining, the fine asperate punctures close-set, denser and stronger on the 

 elytra as usual; color rather pale piceous-brown, the elytra scarcely at all 

 paler, the abdomen black, a little paler at apex, the legs paler, brown; head 

 convex, wider than long, parallel at the sides, the eyes rather large, moderately 

 convex, at a little less than their own length from the base; antennae 

 moderately long, piceous-brown, notably heavy and also sensibly incrassate, 

 the second joint as long as the first but thinner, the third distinctly shorter, 

 the fourth subparallel, distinctly wider than long, the outer joints more ob- 

 trapezoidal as usual and distinctly transverse, the last rather obtuse, rapidly 

 pointed at tip and scarcely so long as the two preceding; prothorax large, 

 convex, subparallel, strongly and evenly rounded at the sides, moderately 

 transverse, much wider than the head and as wide as the elytral base, the 

 apex but little narrower than the subevenly rounded base, the basal angles 

 broadly rounded, unimpressed; elytra rather strongly transverse, with evi- 

 dently diverging and feebly arcuate sides, the suture equal to or barely 

 perceptibly longer than the prothorax; abdomen slightly narrower than the 

 elytra, rapidly tapering, the fifth tergite barely three-fifths as wide as the 

 first and one-half longer than the fourth. Length 1.62 mm.; width 0.4 mm. 

 California (Ojai), Fall. 



Distinct from the others in the rather more broadly fusoid outline 

 and heavy antenna. 



Colpodota repentina n. sp. Rather stout, feebly fusoid, somewhat convex 

 and shining, the punctures fine, asperate, moderately close, very dense and 

 asperulate on the elytra; color rather pale piceous-brown, the abdomen 

 but little darker, the elytra not paler, the legs pale; head rather large, convex, 

 wider than long, parallel at the sides, the eyes at evidently less than their 

 own length from the base; antennae long, piceous, slender and paler basally,, 

 gradually and distinctly incrassate distally, the second joint thinner and a 

 little longer than the first and also distinctly longer than the third, the fourth 

 obtrapezoidal, slightly wider than long, the outer joints distinctly transverse,, 

 the last notably large, pointed from behind the middle to the tip and longer 

 and rather stouter than the two preceding; prothorax transverse and rather 

 large, slightly narrowed and with broadly rounded sides from the somewhat 

 distinct basal angles to the apex, the base rounded, obliquely and gradually 

 subsinuate at the sides, unimpressed; elytra subparallel, moderately short, 

 barely equal in width to the prothorax, the suture fully a fourth longer than 

 the latter; abdomen slightly narrower than the elytra, moderately tapering 

 and with slightly arcuate sides to the fifth tergite, which is three-fifths as.
