BOLITOCHARINA. 



The memhers of this trihe have the anterior and int(3rmediate tarsi 4- 

 jointed, and the posterior tarsi 5-jointed ; they differ very much in 

 general appearance and some of them are amongst the most abnormal of 

 the StaphylinidcB ; the name of this tribe, or that of the preceding, is 

 misleading, for they are by no means exclusively found in fungi or 

 boleti, as many of the species occur under bark and vegetable refuse, 

 and in various situations ; the genus Bracliida was formerly included 

 under Ilomalota, and Sipcdla fesfarea has in our catalogues been con- 

 sidered to be a Leptusa ; it is, however, evidently distinct from that 

 genus, and I have followed Sharp and jNIulsant and Eey in referring it 

 to Si'palia ; there are sixteen British genera contained in the tribe ; their 

 ditt'erences are rather hard to express in words, but a cursory study of 

 type specimens will at once show how widely they differ ; tlie last genus 

 ]\iylla-na is described together with Gijmnusa and Leinapsis at the end 

 of the Aleocharinse.
