Cayenne. 



Serville describes the antennae in his Odontocerce as " filifor- 

 mes, presque setac^es, 5 ou 6 articles en scie." His species 

 would therefore come in the present section. 



10. Odontocera cylindrica^ Serv. I. c. p. 548. 



Brazil. 



It is not stated in the description that the elytra have vitre- 

 ous disks J the position of the species is therefore doubtful. 



11. Antennae more or less abbreviated and dilated. 



A. Thorax narrow, cylindrical. 



a. Bisk of thorax even. 



* Antennce much thickened towards the apex. 



11. Odontocera crocata^ n. sp. 



0. gracillima, postice attenuata, fusco-niger ; anteunis, pedibus et 

 elytris fulvo -croceis, his marginibus et apice late nigris, valde ab- 

 breviatis, apice late truncatis. Long. 3| lin. c? .

 Bates). 



Head coarsely punctured ; eyes voluminous, contiguous in 

 front ; muzzle moderate, narrow. Antennae two thirds the 

 length of the body, thickened towards the tip, saffron tawny ; 

 third to fifth joints slender, linear, seventh to tenth serrate. 

 Thorax very narrow, cylindrical, with longitudinal patches of 

 shallow circular punctures, the patches connected by transverse 

 wrinkles. Elytra just passing the base of the antepenultimate 

 segment, moderately narrowed from after the base, dehiscent 

 at the suture, sharply and broadly truncated at the apex ; sur- 

 face moderately punctured, very sparsely so on the disk, -which
