278 SEKBICOENIA. 



of Dejean, labelled as from Mexico. The synonymy, that referring to Dejean excepted, 

 is given on the authority of Candeze. The figure and description of E. porcatus, 

 Drury, from the Bay of Honduras, would apply equally well to C. bonplandi, Guer., 

 from which the present species chiefly differs in having the epipleurse clothed with 

 elongate luteous scales and the marginal carina of the elytra more deflexed anteriorly.

This species, of which I have seen nine females and five males, is very closely allied 

 to the South-American C. zonatus, Eschsch. ; but differs from it in having the head 

 more deeply excavate, the thorax more parallel, with the hind angles less divergent, less 

 thickened, and more acute, the elytra with the ninth interstice costate and the apices 

 more rounded, and the minute scales of the upper and under surfaces more obscurely 

 coloured. In both species the epipleurse are clothed with elongate white scales f; 

 the male characters are similar. In the Colima specimens the elongate white scales on 

 the elytral striae are almost obliterated on the disc. The white marginal stripe of the 

 elytra is always divided down the middle by the raised ninth interstice. In one of 

 the two examples from Cuernavaca the propleuree have each a longitudinal band of 

 white scales in the centre. The metamorphoses of this insect have been fully 

 described by Dr. E. Duges 5 , who gives numerous figures of the larva and pupa (op. cit. 

 figg. 16-34). A female from Cuernavaca is figured.

We have received three female specimens of this insect from Chihuahua, and there 

 is a Califomian specimen of the same sex in the Janson collection. 



* This figure is incorrect, the anterior and intermediate tibiae only being ciliate in the male. 



f In Candeze's table (Bull. Soc. Ent. Belg. 1886, p. lxvii) the species should follow C. zonatus, in sect. dd.
