Casey — Observations on the Staphylinidae. 27^ 



gradually incrassate from the fourth joint to the tip, the last joint 

 moderate; body very stout, convex, the prothorax transverse, the elytra 

 short; abdominal segments decreasing only slightly in length toward 

 base, the first three tergites feebly impressed basally; integuments dense. 



Europe • Brachida 



Mesosternal process extremely wide, nearly as in Brachida, extending to 

 the posterior limits of the acetabula, where it is separated from the 

 metasternum by a perfectly straight transverse suture; body very short, 

 stout, convex, the head transverse, strongly deflexile, the eyes moder- 

 ate, very prominent and finely faceted, the sides of the head rapidly 

 converging behind them; antennae short, strongly incrassate distally 

 from the small globular fourth joint; abdomen very short, rounded at 

 the sides and constricted at base. Europe * Encephalns 



The foreign genera indicated above may be further alluded 

 to as follows : — 



DiESTOTA Key. — The outline characters of the table are 

 taken from a specimen of the rare species noted in the cata- 

 logue of Heyden, Reitter and Weise under the name mayeti 

 Rey, and kindly given me by Mr. Fauvel, who has also placed 

 the name testacea Kr., on the same label, but I have been 

 unable to find the latter name in the catalogue mentioned. 

 Diestota is at once distinguished from any of the other genera 

 of the subtribe by its narrow neck and disengaged head, and 

 is in many respects a connecting bond between the Gyro- 

 phaenae andBolitocharae, though apparently more properly a 

 member of the former subtribe; at the same time, it may 

 more appropriately form the type of a separate subtribe as 

 maintained by Rey. Dr. Sharp has referred a number of 

 Mexican and South American species to this genus, but the 

 accuracy of this identification is open to some doubt. 



Agaricochara Kr. — This genus is very far from being a 

 subgenus of Gyrophaena, as stated in the catalogue referred 

 to above, the structure of the intermesocoxal jiarts prohibit- 

 ing any such close alliance. The species are minute, with 

 dense punctured integuments and with more elongate elytra 

 than in any other genus of the subtribe. In some characters 

 it betrays a rather close affinity with Eumicrota^ but may be 

 readily distinguished by the characters of the table, which are 

 taken from A. laevicollis Kr.
