Latr. It is red, with three black bands, one on the thorax, 

 another at the base, and the third narrower on middle of the 

 elytra ; from the latter to the tip yellow. The species ai'e 

 all from Brazil, where they inhabit the trunks of dead trees, 

 and are occasionally found creeping upon the barks. 



M. Guerin has also added a genus, newc Adelocera,yfhic\\ he 

 calls Pachyderes. It has the antennae pectinated, first joint 

 large, second small, maxillary palpi, last joint very large, 

 subsecuriform, the joints of the tarsi simple, the penulti- 

 mates bilobed ; the head small, thorax large, dilate, with 

 two spines at the posterior angles ; the elytra long, narrow, 

 dentate at the tip ; the only species is named RuJicoLlis. 



M. Eschcholtz has formed a new genus on a single species, 

 which is allied to Eucnemis, under the name of Epiphasis, 

 with the following characters. The antennae, with the four 

 apical joints very long ; the six preceding very short. 

 The species is named Cornuttts. It is reddish ferrugineous, 

 the head black, the front with a compressed horn ; the thorax 

 black, with the hinder angles ferrugineous. The length is 

 two lines and a half. 



The singular genus Chelo7iarium, Fahr. which has but 

 recently been regarded by Latreille as belonging to the Ela- 

 teridae, has all the aspect of the Clavicornes, in which group 

 it was previously arranged by that author ; according to M. 

 Lacordaire, the Brazilian species of this genus are found upon 

 the leaves and flowers of various plants, from which they drop 

 on the approach of danger. When held between the fingers, 

 they conceal their antennas in the channels of the thorax, fold 

 their legs along the sides of the body, and thus counterfeiting 

 death, they remain in this state a considerable time. 



The next genus we notice is also one of M. Guerin, which 

 is named Lobcederus. The antennas are moniliform, the first 

 joint is very large, and the last very small, ovoid ; labrura 

 very small^ mandibles strong, hooked, with a small tooth under
