STAPHYLINID^E. 45 



of the abdomen barely traceable; punctures very fine and not close-set, 

 evidently separated and but little larger on the elytra; head, eyes and carinae 

 as in the preceding, the head not so transverse; antennae dark piceous-brown, 

 dark testaceous basally, extending well behind the prothorax, the outer 

 joints very moderately transverse, the last longer than the two preceding, 

 the second and third moderately elongate, the latter the longer; prothorax 

 moderately transverse, parallel, evenly and moderately rounded at the sides, 

 much wider than the head and evidently narrower than the elytra, the basal 

 impression small and barely visible; elytra rather large, only moderately 

 transverse, much longer than the prothorax; abdomen slightly narrower than 

 the elytra, parallel, narrowed a little near the apex, the fifth tergite barely 

 as long as the fourth, the sixth (cJ 1 ) rather broadly truncate, moderately but 

 strongly crenulate, the lateral crenule slightly elongate but thick, dentiform; 

 mesosternal process extending well behind the middle of the coxae, gradually 

 and sinuously narrowed to the acute but not at all aciculate apex, which 

 is separated from the large, equilatero-triangular metasternal projection 

 by a rather short, sunken, broadly and feebly convex interval; hind tarsi 

 rather slender, the first joint very much shorter than the second. Length 

 2.65 mm.; width 0.75 mm. Iowa (Cedar Rapids), Brendel. 



Distinguishable from allied species by the rather narrower, less 

 transverse prothorax, sternal and tarsal characters. 



Atheta spadix n. sp. Coloration, sculpture and shining lustre as in the 

 preceding, the abdomen not paler basally, except narrowly and faintly at 

 the apices of the segments, the elytra and legs uniformly pale, the antennae 

 similarly dark piceous-brown and but slightly paler basally; head orbicular, 

 but slightly transverse, the eyes rather prominent, at less than their own 

 length from the base, the carinae fine, almost entire; antennae notably long 

 and thick, gradually and very feebly incrassate, the outer joints but very 

 slightly wider than long, the last distinctly longer than the two preceding, 

 the second moderately, the third distinctly, more elongate ; prothorax rather 

 smaller in size, transverse, distinctly wider than the head and quite as dis- 

 tinctly narrower than the elytra, parallel, evenly and very moderately rounded 

 at the sides, not definitely impressed; elytra rather large, only moderately 

 transverse, very much longer as well as wider than the prothorax; abdomen 

 narrower than the elytra, parallel, narrowing a little apically, the fourth 

 and fifth tergites equal, the sixth (cf) moderately wide and transversely 

 truncate at apex, the truncature strongly, evenly crenate, the lateral crenule 

 larger, rather long, forming a slender, externally rounded process; meso- 

 sternal process extending nearly to apical fourth of the coxae, gradually 

 narrowed and with the apex very slender and acute but not aciculate, sepa- 

 rated from the moderate and angulate metasternal projection by a short 

 depressed interval, which slopes anteriorly under the process; basal joint 

 of the hind tarsi a little shorter and thicker than the second. Length 2.65 

 mm.; width 0.75 mm. New York (near the city). 



A moderately large species, allied to replicans but differing in the 

 longer, more acute mesosternal process, still longer antennae, more 

 nearly entire cephalic carinse and other characters.
