Casey — Observations on the Staphylinidae, 177 



of the elytra are normal and transversely crescentiform. The 

 integuments are finely, very obsoletely reticulate, except the 

 abdomen, which is wholly devoid of minute ground sculpture. 

 The type may be characterized as follows : — 



Form elongate, slender and parallel, normally convex, subalotaceous, the 

 abdomen shining, pale ferruginous throughout, the legs and anten- 

 nae concolorous; head and abdominal dorsal plates piceous, pale 

 toward apex, the sixth wholly pale ; pubescence rather abundant, de- 

 cumbent and distinct; head somewhat elongate, three-fifths as wide as 

 the prothorax, widest near the base, the sides arcuate, the punctures 

 sparse and indistinct, the antennae stout, somewhat longer than the 

 head and prothorax, strongly incrassate distally, the outer joints trans- 

 verse, the second and third elongate and equal; prothorax scarcely 

 more than a fourth wider than long, subparallel, the sides evenly, 

 rather strongly and the base feebly, arcuate, the apex narrower than 

 the base, the basal angles obtuse and rounded, the punctures some- 

 what sparse and very indistinct; elytra scarcely visibly wider and 

 somewhat shorter than the prothorax, the outer side equal in length, 

 to the side of the latter, the suture scarcely more than two-thirds as 

 long as the median line, the punctures rather strong, asperulate and 

 close-set; abdomen long, subparallel, slightly narrower than the elytra, 

 finely punctulate, very sparsely toward tip, the punctures slightly 

 coarser, rather close-set and distinct in the basal impressions ; legs 

 rather long, finely, closely setose. Length 4.5 mm.; width 0.8 mm.

There are some inaccuracies in the original description 

 which are here corrected; the abdomen, for example, has no 

 subapical cloud, though the apical pale margin of the fourth 

 tergite is somewhat narrower than that of the basal segments, 

 and the punctures of the basal depressions are coarser than 

 the others. The mesosternal process does not more than just 

 attain the acute apex of the metasternum, but on a lower 

 level — in the natural position of the body. This species is 

 said to inhabit caves, but probably only incidentally. 



Pinalocliara n. gen. 



In many structural features and in appearance this genus 

 resembles both Maseochara and Umplenota, having a some- 

 what similar reticulate sculpture, the depressed form and 

 short basal joint of the hind tarsi characterizing Emplenota 

 and the feebly inflexed hypomera of Maseochara. It is
