280 COLEOPTERA OF NORTH AMERICA. 



Sub-Family L PARANDRIDAE. 



The body is elongate, parallel, smooth and shining ; head 

 broad, eyes transverse, convex, rather coarsely granulated, feebly 

 emarginate ; antennas extending to the base of the prothorax, in 

 front of the eyes, near the base of the mandibles, under distinct 

 lateral ridges, polished, scape short and thick, strongly con- 

 stricted at base ; 2cl joint half as long as 3d ; 3-10 equal, sub- 

 quadrate, constricted at base, flattened, with two deep grooves 

 on the under surface, separated by a convex space, but limited 

 on their outer edge by an acute ridge; llth joint longer, ob- 

 liquely truncate and pointed, with the same two grooves, and an 

 apical fovea. Mandibles dentate, longer in $ than $ ; labrum 

 pointed, connate with the front ; mentum very transverse, clos- 

 ing the buccal fissure, bisinuate in front, ligula corneous very 

 transverse, broadly truncato-sinuate in front ; palpi short, labials 

 inserted at the sides of the ligula, widely distant ; maxillaries not 

 longer, last joint cylindrical; maxilla? with one very slender and 

 small lobe, sparsely ciliate at tip. Prothorax quadrate, margined 

 at the sides ; mesonotum punctured, without stridulating plate, 

 not distinctly separated from the scutellum, which is triangular 

 rounded at tip. Elytra parallel, margined, rounded at tip; epi- 

 pleurae extending to the sutural tip ; wings perfect. Prosternum 

 distinct between the coxae, which are large, not prominent, trans- 

 verse, and inclosed behind ; middle coxae oval, cavities widely 

 open externally, mesosternum parallel, truncate or submarginate 

 at tip ; hind coxa? not prominent, transverse, extending to the 

 sides of the abdomen ; episterna of metathorax parallel, narrow; 

 ventral segments 5, equal, alike in both sexes, intercoxal process 

 acute. Legs rather short, thighs compressed ; tibia? compressed, 

 outer angle acute, spurs rather strong, tarsi slender, without 

 brush beneath ; 4th joint half as large as the 3d, 5th as long as 

 the others united, claws strong, paronychium slender, small, with 

 two terminal setae. 



The species of Parandra live under pine bark, and are not 

 very well defined. 



The affinities of this genus with Prionidae are quite apparent, 

 but those with Lucanidae are equally obvious, with also some 

 tendency towards Cucujidae in Passandra, Catogenus, &c.
