Casey — Observations on the Staphylinidae. 231 



Cardiola Rey. 



The occurrence of this genus in America is probably due to 

 recent fortuitous importation and it is by no means certain 

 that it has established itself. It is one of the more isolated 

 of the Falagriae, as may be readily conceived by a glance at 

 the characters given in the table, and is not in any sense a 

 subgenus of Falagria. In the present subtribe the bottom of 

 the middle coxal cavities slopes gently upward posteriorly, 

 merging gradually into the metasternal surface behind in all 

 the genera except Cardiola, where the cavities are abruptly 

 deep and with steep walls on all sides as before stated, and 

 their edges are still more sharply defined throughout by a 

 fine but strong bead, causing the metasternal projection to be 

 abruptly limited at the sides, the latter condition not else- 

 where observable except in Lophagria. The single species 

 may be defined as follows ; — 



Form rather stout, convex, highly polished, dark rufo-testaceous, the head 

 and abdomen behind the second segment blackish; legs and antennae 

 pale; vestiture rather long and coarse, decumbent, yellowish in color and 

 distinct but not conspicuous; punctures of the head, pronotum and 

 «lytra extremely minute, sparse and indistinct, the elytra not more 

 strongly sculptured toward the scutellum, the latter minutely but acutely, 

 not densely granulose ; abdomen closely and more coarsely, asperately 

 punctate, coarsely toward base, finely posteriorly, the impressions with 

 more or less sparse and coarse punctures; head small, the very large, 

 deep subbasal impression impunctate; antennae extending to the 

 middle of the elytra, the subapical joints equal in length, moderately 

 transverse, the second and third equally elongate; prothorax small, 

 slightly wider than the head, somewhat wider than long, the sides ar- 

 cuately and rather strongly converging to the base, the medial im- 

 pression broad and shallow, obsolete at apex and in about basal two- 

 fifths; elytra transverse, fully four-fifihs wider and two-fifths longer 

 than the prothorax, convex, the humeri very widely exposed, the sides 

 slightly diverging from the humeri, broadly and distinctly arcuate; 

 abdomen narrower than the elytra, the sides parallel and straight, the 

 border thick. Length 2.6 mm.; width 0.65 mm. Pennsylvania (Mt. 

 Airy) ; common in Europe obscar a Grav. 



The single American example before me is wholly identical 

 in every way with the European, indicating that, like Eulissus 

 fulgidus Fab., to be subsequently described, it is a recent
