Casey — Observations on the Staphylinidae. 395 



well rounded, the sides but feebly converging and slisihtly arcuate 

 throughout; dorsal and sublateral series almost even, composed of very 

 small and widely spaced punctures, the former about ten, the latter 

 about five in number; there are also some rather close-set punctures 

 along the aatero lateral margin; elytra slightly elongate,, somewhat 

 longtir and but little wider than ttie prottiorax, the punctures very 

 small, rather sparse, arranged as in hamatus, the outer of the two 

 medial series less distinct; abdomen but little narrower than the elytra, 

 convex, finely but very distinctly and only moderately sparsely punctu- 

 late, stiil more distinctly beneath. Length 6.7-7.3 mm. ; width 1. mm 

 Iowa (Iowa City), — H. F. Wickham veniicatiis n. sp. 



Body nearly similar to the preceding but much smaller, with less developed 

 head and less minute punctuation, the coloration and lustie similar 

 throuj;hout, the prothorax rather less intenf^ely blacls, the antennae 

 similar in color and structure; head rather small, similar to that of 

 vernicatus, the punctures a little larger and somewhat less remotely 

 separated but still very sparse, very minute on the tlanks and under 

 surface and rather sparser; prothoras slightly elongate, distinctly 

 wider than the head, similar to that of vernicatus but narrower and 

 more elongate aud with the dorsal and sublateral series much less 

 regular, with the punctures stronger and more close- set, with nume- 

 rous outlying punctures anteriorly and more scattered toward the 

 anterior angles; elytra but little longer than wide, somewhat shorter 

 thin the prothorax and only just visibly wider, the punctures sparse but 

 stronger than in the preceding, more narrowly aggregated along the 

 suture and usually arranged in three series along the middle; abdomen 

 almost similar. Length 5.0-5.8 mm.; width 0.8-0.85 mm. Ohio (Cin- 

 cinnati), — Chas. Dury micans n. sp. 



3 — Form sleudev, black, the antennae, legs aud elytra dark red, the abdo- 

 men dark piceous, with the tip rufo-piceous; head convex, elongate, 

 suboval, rounded behind, very sparsely punctured at the sides, the 

 punctures coarse; oblique ocular grooves short; under surface with a 

 few scattered coarse punctures, nearly smooth behind; prothorax 

 elongate -oblong, with much rounded angles; dorsal series of 9-10 

 strongly marked punctures, the sublateral series curved, well defined, 

 of 9-10 punctures; between the two and near the front margin there is 

 & group of four punctures, also some near the front angles; elytra dis- 

 tinctly and sparsely but not deeply punctured almost in rows, Length 

 7.5 mm. Michigan (Detroit) c.giilarig Lee. 



Group IV. 



Closely resembles " Xan«/ioJ{?i!is hamatus,'''' differing by the shorter frontal 

 groove*, by the gular sutures being effaced and the under surface of the 

 head smooth between the punctures, instead of finely strigose; there 

 are also some large itunctures between the dorsal and sublateral series 

 of the prothorax, which cause the latter series to appear irregular; the 

 elytra are more strongly punctured and the punctures are not arranged 

 in series; the body is testaceous-brown in color, with the head darker
