possible that divisum may be a variety of dorsale, but it is certainly 

 not a variety of typicum. 



Secondly. C. dorsale, Xewm., is placed as a variety of reticulatwm, 

 Fabr. (Syst. Ent., p. 203). The description of tliis latter docs not, 

 however, accord with dorsale. The expressions " Statura P. [Pyro- 

 chroa] bicoloris, at duplo major," "Elvira plana," " sterno flavo," 

 are better applied to typicum than to dorsale.

The species of this genus have the elytra ample, each with nine 

 costae, the second, fourth, and eighth much more elevated than the 

 others ; the interstices are divided into quadrangular spaces by 

 transverse ncrvures.

Antennae strongly dentate. Thorax rather broad, the posterior 

 angles very acute and diverging, the anterior angles sometimes 

 pitchy yellow. Elytra each with nine fine costae, the second, fourth, 

 and eighth more elevated, the interstices divided into square spaces 

 by transverse nervures ; the shoulders more or less dull yellow. 



The type specimen is very small, and has the thorax entirely 

 black. 



CELETES. 

 Neicm., Entom. Mag., 1838, v. p. 381. 



This genus is distinguished from Calopteron by the antennae of 

 the males having the branches arising from the base of the joints. 

 The elytra have each four costae, the interstices with transverse 

 nervures.
