26 Mr. J. S. Baly's descriptions of new genera 



margine postico obtuse trimcato, medio obsolete sinuato; 

 disco piano, pone medium concavo. 



Type, Cypliodera Chlamydiformis ( Cadmus\ Germ. 



Genus Beachycaulus, Fairm. 



Ann. Ent. Soc. Fran. 1843, p. 14, tab. i. & ii. fig. 7—9. 



Oncliosorna, Saunders; Cadmus ^ pars, Suffrian, Chapuis. 



Corpus oblongo-ovatum aut subquadrato-ovatum, con- 

 vexum, pube squamiformi vestitum, supra rarius glabrum. 

 Caput tlioraci insertum; oculis ovalibus, intus profiinde 

 angulatim emarginatis; antennis filiformibus, corporis 

 dimidio vix longioribus $ , illo brevioribus 2 . Thorax con- 

 vesus, dorso bimamillosus, lateribus denticulatis. Sciitellum 

 trigonatum, apice late truncatum. Elytra thoracis basi 

 jequilata aut pauUo latiora, valde convexa, pygjdium 

 amplectentia ; rugosa, tuberculis et vittis nonnullis 

 instructa; lateribus ante medium vix lobatis. Pedes 

 robusti, tar sis latis, unguiculis basi incrassatis. Pro- 

 sternum late oblongum, aut oblongum, margine postico 

 obtuso aut bilobato ; disco piano, interdum antice elevato, 

 et ibi longitudinaliter excavato. 



The species of Bracliycaulus may be divided into two 

 sections, dependent on the form of the hinder margin of 

 the prosternum. 



The double tuberosity of the upper surface of the thorax, 

 combined with the short robust form, and the short 

 antennje in both sexes, will at once separate the Bracliy- 

 caulus from any other genus having toothed lateral mar- 

 gins to the thorax. 



Cadmus rugosus, foveicollis, dorsalis, Klugii and 

 Eioingii, Saunders, as also colossus, Chapuis, belong to 

 the present generic group. 



Genus Cadmus, Erichs.

 longioribus $ ; illo sequilongis aut patdlo brevioribus ? .
