CHALCOLEPIDIUS. 285 



scales, with minute olivaceous scales intermixed ; but in two of the females from 

 Jalapa, and in the two females from Chontales, the scales on these parts are nearly all 

 small and olivaceous. The anterior tibiae in the males are armed on the inner edge 

 with about ten fine sharp teeth, and the antennse in this sex have the joints from the 

 fourth considerably produced at their inner apical angles. C. mexicanus may be known 

 from C. oacydatus by the less acute sutural angles of the elytra, and from the South- 

 American C. lemoinei by the less divergent hind angles of the thorax. We figure a 

 male from Mirador and a female from Jalapa.

" Niger, squamulis minutissimis olivaceo-cinereis similiter et densissime vestitus ; antennis artieulo secundo 

 brevissimo, tertio triangulari, sequentibus subquadratis ; prothorace latitudine longiore, basi constricto, 

 regulariter convexo, crebre punctulato et insequali, angulis posticis parvis fortiter divaricatis ; scutello 

 transverso ; elytris sulcatis, sulcis punctatis ; subtus niger et squamulis concoloribus obductas. — Long. 40, 

 lat. 11 millim."

Described from a single female example. Allied to C. rubripennis, Lee, from Lower 

 California.

Chalcolepidius behrensi, Cand. Bull. Soc. Ent. Belg. 1886, p. lxx 1 . 



" Niger, confertissime squamulis minutissimis olivaceis vestitus ; antenuis nigris, artieulo secundo brevi, tertio 

 trian<nilari : prothorace longo, basi et apice angustato, sequaliter convexo, confertissime punctulato ; 

 scutello transverso ; elytris striato-punctatis ; subtus concolor. — Long. 30, lat. 8| millim." 



Hab. Mexico (Behrens 1 ). 



" Near C. lenzi, but smaller ; the greenish scales less dense, the thorax much longer 

 and more narrowed in front, its surface not uneven, the elytra striated, but not 

 sulcate." 



26. Chalcolepidius jekeli. (Tab. XII. fig. 13, $ .) 



Chalcolepidius jekeli, Cand. Eevis. Elat. p. 162 (1874) l ; Bull. Soc. Ent. Belg. 1886, p. lxx 2 . 

 Hab. Guatemala 2 , Las Mercedes and Zapote (Champion). 



This lar^e species closely resembles C. lacordairei, which occurs at the same localities 

 in Guatemala ; but may be easily known from that insect by its more elongate and 

 narrower form, and the differently shaped scutellum. Four female examples were 

 found by myself on the Pacific slope of Guatemala, and I believe it has also been found 

 by Sefior Juan Rodriguez. The original locality given by Candeze l was Colombia* A 

 female from Las Mercedes is figured.
