and conical ; the posterior coxae transverse. Tarsi variable in the

Tribe 1. ALEOCHARINA. 



Maxillae with the outer margin of the inner lobe corneous, the 

 inner margin membranous and ciliate ; maxillary palpi moderately 

 elongate, the terminal joint small, subulate and generally much 

 shorter than the preceding one : in Aleochara and Correa there is 

 a very small additional joint. Eyes not very prominent. 



The following key, which is chiefly based on the tables of 

 Lacordaire and Fauvel, will facilitate the determination of the 

 genera of this tribe : — 



I. Antennas 11-jointed. 



A. Anterior tarsi 4-jointed, intermediate and posterior 



5-jointed. 



1. Prothorax M r ith the angles rounded or not produced. 



a. Antennas filiform, robust or slightly thickened 

 towards the apex. 



aa. Head carried on a very fine neck. 



i. Intermediate coxae remote Falagria. 



ii. Intermediate coxae near together Myrmecopora 



bb. Head not carried on a slender neck. 



i. First joint of the posterior tarsi very long. 



* Mesosternal plate acute ; intermediate coxae 



subcontiguous Gnypeta. 



** Mesosternal plate rounded ; intermediate coxae 



remote Myrmedonia. 



ii. First joint of the posterior tarsi not very long, 

 not as long as the two following together. 



* Intermediate coxae remote Pelioptera. 



** Intermediate coxie near together ...Homalota. 



b. Antennae with joints 2-6 strongly dilated externally. Apphiana. 



2. Prothorax with the posterior angles produced Dabra.
