LATHROBIDZE. 87 



DESCRIPTION. 



Body black, rather glossy, hairy except the prothorax. Head obovate, minutely and thickly 

 punctured ; mandibles, palpi, and what remains of its mutilated antenna?, dark chestnut : prothorax 

 an oblong square with all the angles rounded; punctured, but not very thickly, with scarcely any 

 smooth longitudinal space: elytra longer than the prothorax, thickly punctured, of a dark chestnut: 

 legs mahogany, cubit armed with a short wide tooth or prominence on the inner side at the base, the 

 four first joints of the hand are dilated, indicating probably that the specimen is a male. This 

 appears to be the representative of L. dentatum F, which it nearly resembles, but the elytra are 

 considerably longer, the colour of the legs is darker, and the humerus, or anterior thigh, is propor- 

 tionally smaller and has no tooth.

DESCRIPTION. 



This species a good deal resembles the preceding, but the palpi, mouth, scape of the antenna?, and 

 legs, are testaceous, the remainder of the antennae is darker; mandibles chestnut. Head oblong : ante- 

 rior angles of the prothorax scarcely rounded; a distinct intermediate longitudinal smooth space 

 adjoining which is a series of punctures strikingly distinguishes this species from L. puncticolle, 

 the sides of the prothorax are covered with scattered punctures : the tip of the segments of the 

 abdomen, ventral as well as dorsal, is testaceous.
