444 COLEOPTERA. 



oleven-jointetl antenutt, which are verticillate, with long hairs, 



are inserted at the margin of the front, and the club is long 

 and loosely articulated. The beetles live under the bark 

 of trees and in ants' nests. The larvae are carnivorous, 

 being very active, without ocelli, and with cjiindrical 

 bodies, with four-jointed antennse and long four-jointed 

 legs. TricJiopteryx is known by its pubescent bodj', 

 and laminate posterior coxse. One species is one-third 

 of a line long ; others are still smaller. The larva

Phalacrid.e Erichson. "A small number of oval or 

 rounded oval, convex, shining insects, constitute this faniilj-. 

 They are found on flowers, and sometimes nnder bark. The 

 elytra have sometimes approximate rows of small punctures, 

 but more usually only a sntural stria. The scutellum is larger 

 than usual, trianguhir. One of the four genera (Tol3'phus) 

 of this fomily is wanting in our fauna. The other three are 

 separated by the form of the posterior tarsi." (Leconte.) In 

 Phalacrus tlie anterior and posterior tarsi are of the same 

 length. The larvae are vegetable feeders, living iu the flowers 

 of composite plants. 



NiTiDULARi^ Latreille. This family includes small oval or 

 elliptical, flattened beetles, which are sometimes almost globu- 

 lar. The head is suddenly narrowed before the insertion of 

 the antennae, thus forming a short beak, and the antennae may 

 ^ be partially retracted into a groove under 



the eyes. The larvae are both carnivorous 

 and vegetable-feeders ; they are elongated, 

 with two to four-jointed antennae, three ocelli 

 on each side, with a flattened hairy body, 

 ending in four small, horny, recurved tuber- 

 cles. The pupae may be found under the 

 surface of the ground in earth and sawdust. 

 CarpopMlus has the second and third abdominal segments 

 short, while the first, fourth and fifth are longer, and the claws 

 are simple. CarpopMlus antiquus Mels. is a well known spe-
