234 COLEOPTERA OF NORTH AMERICA. 



Tribe VIII.— TRACHYSCELOJI. 



Body ovate, convex, winged ; head received in the thorax as far 

 as the eyes ; front truncate, not dilated at the sides ; labruin promi- 

 nent ; eyes emarginate, coarsely granulated ; antennas short, thick, 

 11-jointed; mentum small, inserted upon a gular peduncle; ligula 

 prominent ; maxilla? exposed ; palpi not dilated ; gular sutures 

 confluent along the medial line ; elytra with narrow epipleura?. 

 Anterior coxa? transverse ; middle coxa? with distinct trochantiu ; 

 hind coxa? approximate ; intercoxal process of abdomen acute ; 

 legs stout, fossorial ; tibial spurs distinct ; tarsi short, spinous 

 beneath. 



Trachyscelis jlavipes Mels., found on the sea-shore of the 

 Southern States, represents this tribe in our fauna. It resembles 

 in appearance a small iEgialia. The margin of the body and the 

 prosternum are clothed with long hairs ; the hind tibia? are broad 

 and thick, and densely covered externally with short spines, 

 arranged without order.

Body oval or rounded, usually winged ; head received in the 

 thorax as far as the eyes ; front somewhat dilated at the sides, 

 covering the base of the mandibles ; epistoma truncate, separated 

 from the prominent labrum by a short, coriaceous clypeus ; eyes 

 transverse, scarcely emarginate, coarsely granulated ; antenna? 

 slightly thickened externally ; mentum small, inserted upon a 

 gular peduncle ; ligula and maxilla? exposed ; palpi not dilated ; 

 gular sutures diverging ; elytra with narrow epipleura?. Anterior 

 coxa? transverse ; middle coxa? with distinct trochantiu ; hind 

 coxa? not widely separated ; intercoxal process triangular, sub-

 tarsi setose beneath. 



The species of Phaleria are found on the sea-shore on the 

 Atlantic and Pacific coasts. 



Tribe X.— CRYPTICINI. 



Body oval, winged ; head received in the thorax as far as the 

 eyes, which are transverse, reniform, small, and moderately granu- 

 lated ; front moderately dilated at the sides, over the base of the
