 Staphylinid-like characteristics (^ig 193). The genus Euaesthetus . which 

 in Erichson and Kraatz is placed in the group Stenini, is, on account of 

 4- jointed tarsi and small eyes etc. separated from this eind placed in a 

 different group , Euaesthetini . Otherwise the groups are here held within 

 the boundary as found in Kraatz. 



Key to the Oroups. 



1. Antennae 11- jointed, only exceptionally 10- jointed ( Oligota , Hypocyptus ) 



2. 



tetennae 9-jointed with knob-shaped distal joint (Fig. 193). Frothorax 



at each side anteriorly with a deep antennal groove... 11. Micropeplini . 



2. Spiracula of prothorax behind fore-coxae exposed and visible, inasmuch 



as the prothorax back of the large, conical, protecting coxae is 



entirely membranous (?ig. 5 and 5) 3. 



Spiracula of prothorax as a rule not visible, but covered by the most 



often entirely chitinized, or at least only at middle membranous pro- 

 thoracic chitin-shell; only exceptionally ( Cryptobium. Plalystethus ) 

 are the spiracula entirely covered 2j.» 



3. Antennae inserted on forehead near the foremost inner margin of the 



eye (Pig. lk> 19 et al.). Dorsum of elytra not separated from their 

 epipleura by a carina, (except in Dinar da) . Hind coxae broad, their 



trochanter rather long, supporting 1. Aleocharini . 



Antennae inserted before the eyes beneath side-margin of forehead (Pig. 

 101, 108). Slytral dorsum by a sharp carina separated from the 

 deflected side-plane, (except in rrichophya ). Hind coxae broad
