ALEOCHARIDES. 



A. Paraglossae reacliiiig far beyond l)aso of ligula. 



Anterior tarsi with four joints, hinder pairs with five. 

 Antennae with eleven joints. 



a. Labial palpi short. 



I. Ligula cleft. 



1. Apex of ligula ending in four points. 



Ligula long and narrow, paraglossae very small, narrow 

 and pointed ; labial palpi two-jointed ; head globular, 

 separated from thorax by a thin neck ; thorax scarcely 

 half as broad as elytra, rounded in front, with longitu- 

 dinal impressions at base ; elytra as long as together broad,

Alitalia, Leach. 



2, Apex of ligula ending in two points. 

 xL A, Ligula short. 



a a. Mandibles very slender and produced. 



Chiefly distinguished ixoni Falagria, by the very slender and 

 produced mandibles, of which the right hand one has on the 

 inner-side below the middle a very large strong tooth, on 

 the lower side of which is another and much smaller tooth ; 

 left hand mandible attenuate, strongly curved below the 

 middle and with no tooth ; labrum transverse, slightly 

 emarginate on each side near anterior angles ; last joint of 

 maxillary palpi small, but not so attenuate as in Falagria ; 

 last joint of labial palpi scarcely half as broad as the first 

 and a little narrowed at apex. Borhoro2)ora, Kr. 



b b. Mandibles not slender and produced. 



Paraglossae prominent; labial palpi three-jointed, last 

 joint thickened at apex ; head prominent, constricted 

 behind, separated from thorax by a thin neck ; thorax nar- 

 rowed behind, in general deeply furrowed ; abdomen 

 broadly bordered ; first joint of posterior tarsi longer than 

 the rest. Falagria, Leach. 



S JB. Ligula elongate. 



Inner margin of inner lobe of maxillae with the bristles 

 toward apex standing not very closely ; third joint of
