STAPHYLINID/E. 137 



somewhat slender or only very moderately incrassate distally, the 

 eyes well developed, the elytra sinuate externally at the apices and 

 the hypomera very strongly inflexed, so that they are wholly invis- 

 ible from the sides as in Acrotona and Eurypronota, the latter of 

 which may be attached to the former as a subgenus represented 

 only by discreta, a species not approached by any other in the 

 singularity of its outline. The type of Dolosota is Eurypronota 

 scapula Csy. The male sexual characters in the genus are not 

 apparent, all the numerous examples examined having the fifth 

 tergite very broadly rounded or subtruncate and perfectly even. 

 Besides scapula, the following numerous species are present in my 

 collection from various parts of the Atlantic region, and they may 

 be divided into two very distinct sections as follows : 



I Head finely and inconspicuously punctate as in scapula. 



This group may be divided into two rather arbitrary subgroups, 

 depending upon the relative size of the head. In the following five 

 species the head is comparatively well developed, although much 

 narrower than the prothorax: 



Dolosota redundans n. sp. Rather stout and convex, subparallel, moder- 

 ately shining, the punctures fine, not dense, asperulate, strongly so on the 

 elytra, also rather close-set and asperulate on the abdomen, where the re- 

 ticulation is rather coarse, irregular and distinct; head and abdomen black, 

 the latter pale at tip and largely toward base, the prothorax rufo-piceous, 

 the elytra pale flavo-testaceous. the legs and antennae pale brownish-flavate 

 throughout; pubescence pale rather distinct; head strongly transverse, 

 the eyes moderate, rather coarsely faceted, at less than their own length from 

 the base, the tempora just visibly more prominent than the eyes; antennae 

 moderately long, slender, very feebly incrassate, bristling with long setae, the 

 first three joints decreasing in length and thickness but not very rapidly, 

 four to six slightly longer than wide, the outer joints only very slightly wider 

 than long, the last rather large, pointed, longer than the two preceding; 

 prothorax large, convex, transverse, strongly rounded at the sides, the latter 

 gradually more converging before the middle, just visibly wider than the 

 base and narrower than the apex of the elytra, with a very small and feeble 

 subbasal fovea; elytra short, with diverging sides, the suture only just visibly 

 longer than the prothorax; abdomen at base nearly as wide as the elytra, 

 very gradually and moderately tapering thence to the tip, the tergites rather 

 short, the fifth a little longer than the fourth. Length 1.65-1.75 mm.; 

 width 0.42-0.48 mm. New York (Catskill Mts.). 



This is one of the least minute species of the genus and may be 

 recognized easily by the relatively wider elytra. The following 

 may be regarded as a subspecies :
