 antla (Edge)-, Guatemala, Purula in Vera Paz (Champion) ; Costa Eica (Van Patten, 

 coll. Janson). 



In this species the ground-colour of the elytra varies from black to bright ferru- 

 ginous; the scales of the upper surface also vary in colour. The thorax has a 

 narrow bare space down the middle of the disc ; this space, however, in freshly emerged 

 examples is sparsely clothed with scales. The male, three specimens of which are 

 before me, has the anterior and intermediate tibiae abruptly dilated on the inner side at 

 the apex ; neither the tibiae nor tarsi are ciliate. We figure two examples : a typical 

 male from Misantla, and a female of a variety from Purula.

" Niger, squamulis olivaceis sparsis, striis elytrorum marginibusque albicanti vestitus ; antennis nigris, articulo 

 tertio minuto ; prothorace latitudine longiore, parallelo, apice rotundatim angustato, dorso aequali, angulis 

 posticis vix divaricatis ; scutello medio tumido ; elytris striis parum punctatis, per paria approximatis ; 

 subtus albicans."

According to Candeze, this species resembles C. mexicanus in colour, but is broader ; 

 the size is not given.

I have seen twenty specimens of this species, including seven males. All the females 

 have the sides of the thorax and elytra, and a line down each of the stria?, clothed with 

 elongate white scales, the scales on the rest of the upper surface being minute and 

 olivaceous ; the males (the var. a of Candeze) have only the base of the thorax, the 

 scutellum, and the base, and sometimes the sides anteriorly, of the elytra, clothed with 

 white scales. The legs and under surface are thickly clothed with elongate white
