BLPRESTIDAE. 195 



The groups represented in our fauna form the following 

 tribes : — 



A. Hind coxffi with the plates distinctly dilated internally, cut off exter- 



nally by the prolongation of the abdomen ; their antei-ior margin 

 straight, the hind margin oblique ; 

 Mesosternum divided ; 



Metathoracic side pieces narrow ; fourth tarsal joint not lobed. 



BUPKESTI.M. 



Metathoracic side pieces wide ; fourth tarsal joint cleft. Schizopiki. 

 Mesosternum emarginate, not divided. Thkincopygini. 



B. Hind cox;e with the plates scarcely dilated internally ; 



Front not narrowed by the insertion of the antennae ; thorax trun- 

 cate at base ; 

 Mesosternum emarginate ; not divided. Julodini. 



Mesosternum scarcely visible. _, Mastogenini. 



ront narrowed by the insertion of the antennae ; thorax lobed at the 

 base. Agrilim. 



Tribe I.— BUPRESTIIVI. 



The front is usually not contracted by the insertion of the 

 antennae, but in Clirysobothrcs is as much so as in the tribe Agri- 

 lini; the prosternum is sometimes obtusely, sometimes acutely 

 angulated on the sides behind the co.xce, and its lateral sutures 

 are oblique; the mesosternum is always divided, so that the 

 cavity for the reception of the prosternum is formed both by the 

 meso- and metasternum ; the side pieces of the latter are always 

 visible, and the epiniera are triangular, with the hind margin 

 sometimes straight, and applied to the coxEe, sometimes partly 

 covered by the prolongation of the abdomen, which intervenes 

 between the coxae and the margin of the body. The hind cox;c 

 are broader internally ; their anterior margin is straight and 

 transverse; the hind margin is oblique. The antennal pores are 

 diffused on the sides of the joints in the first group, concentrated 

 in marginal foveas in the others. The species are more or less 

 flattened in form. 



Our groups are the following : — 

 Epiraera of metathorax triangular, uncovered ; prosternum obtusely angu- 

 lated behind the coxae ; 



Mesost(!rnnm and metasternum closely united. Chai-cophok-^?. 



Mesosternal suture distinct. Bi;pkestks. 



Epimera of metathorax partly covered by abdomen ; prosternum acutely 

 angulated behind the coxae ; 



Front not contracted by insertion of antenme. Anthaxi/e.
