FALAGRIA MANNH. AND ITS RELATIVES. 



By a. Fenyes, 

 Pasadena, Cal. 



The genera grouped with Falagria Mannh. are to be distinguished 

 from the other genera of the tribe Myrmedoniini (subfam. Aleo- 

 charina?, fam. Staphylinidae, Col.) by the following characters: head 

 with a narrow neck; genas not margined; antennae ii-jointed; ligula 

 bifid; paraglossae visible; inner lobe of the maxillae on the inner 

 margin spinose and hairy, outer lobe at tip finely ciliate; maxillary 

 palpi 4", labial 3-jointed; the first two free ventral segments of the 

 abdomen constricted at base ; prosternum behind the front coxas on 

 each side with a corneous plate; middle coxae separated (except 

 in Drcpanopora Brnhr.) ; tarsi 4-5 jointed, hind tarsi with joint i 

 elongate.
