CcLsey — Observations on the Staphylinidae. 233 



be observed in some individuals, which is barely traceable or 

 obsolete in others ; there is never any trace of the medial 

 carinule of Lorinota. The middle coxae are more widely 

 separated and the mesosternal process shorter than in any 

 other genus of the subtribe ; the coxae are, in fact, very re- 

 mote in some species. The elevation of the entire meso- 

 sternum above the metasternum and intermesocoxal parts is 

 entirely peculiar to Ghitalia. The antennae are rather long 

 and thick, the last joint notably short and stout, the subapical 

 joints compactly joined but variable in form. The prothorax 

 is not only strongly narrowed at base but broadly and sinu- 

 ously constricted behind the widely inflated anterior part, 

 and the surface sloping toward the profound median sulcus 

 is frequently closely granulose, this peculiar sculpture appear- 

 ing also, in very minute form, on the basal parts of the elytra 

 toward the scutellum. The sculpture of the abdominal im- 

 pressions varies a good deal and gives opportunity for a di- 

 vision of the species as follows : — 



PTinctiiTes of the abdominal impressions very coarse and closely, polygonally 

 crowded 2 



Fnnctares of the impressions coarse bat smaller, rounded and always 

 clearly separated; species smaller in size, the prothorax relatively 

 mnch smaller and less inflated at the sides anteriorly, the head more 

 truncate at base 7 



2 — Large punctures of the abdominal impressions shallow, with flat floors 

 which are densely and minutely punctulate. Form rather stout, con- 

 vex, shining, pale brownish-testaceous in color with feeble subaeneous 

 reflection, the head slightly darker, the abdomen behind the third seg- 

 ment clouded with blackish ; legs and antennae pale; vestiture incon- 

 spicuous; punctures of the head fine but distinct, sparse, those of the 

 pronotum finer and sparse but becoming larger, closer and granose 

 toward the sulcus except at apex, of the elytra very minute, sparse and 

 inconspicuous, finely granulose and close toward the scutellum, of the 

 abdomen sparse, fine and less sparse apically, strongly asperate toward 

 base ; head parallel at the sides with broadly rounded basal angles, the 

 surface feebly impressed on the median line of the occiput; antennae 

 thick, extending about to the end of the elytra, moderately incrassate, 

 the subapical joints slightly wider than long, the tenth slightly longer 

 than the ninth, the eleventh very short, stout and oval, the third much 

 elongated, longer than the second, the latter as long as the first but 

 thinner ; prothorax fully as wide as long, somewhat wider than the head, 

 the sides anteriorly strongly rounded, prominent, thence very strongly 

 converging and strongly siauate to the base, the sulcus deep, widely Im-
