CHALCOLEPIDIUS. 279 



C. apacheanus, Casey, is based upon abraded examples of this species ; our Chihuahua 

 specimens are in similar condition, owing to immersion in alcohol.

A common insect in the forest-region of the Pacific slope of Guatemala, also occur- 

 ring sparingly in Vera Paz. Candeze gives 2 San Diego, California, as a locality, but 

 this requires confirmation ; his southern localities refer to the subsequently described 

 C. eocquisitus. I have seen about ninety specimens of C. lacordairei, five only of which 

 are males ; the ciliate tarsus and tibia in this sex is shown by Candeze, fig. Qf. 



The Mexican specimens in our collection are very dark in colour, those from Cerro 

 de Plumas resembling the variety mentioned by Candeze 2 as from California; the 

 latter have the scales brown on the dorsum and violaceous at the sides and beneath ; 

 the single specimen from Guererro has the scales olive-grey on the back and bronze 

 at the sides. We figure a variety from Dos Arroyos in Western Mexico. 



9. Chalcolepidius exquisitus. (Tab. XL fig. 24, <s .)

This species, or variety, replaces C. lacordairei in the southern portions of Central 

 America, the two insects apparently occurring together in Costa Rica and Nicaragua *. 

 All the specimens found by myself in the State of Panama, upwards of sixty, are 

 clothed with greenish scales — the colour varying to golden-green or olivaceous-green ; 

 in some of those from Nicaragua and Costa Rica the scales are bluish or violaceous, 

 these specimens resembling C. lacordairei in colour. The thorax, as noted by Candeze, 

 is usually much smoother than in C. lacordairei, but in some of the Panama specimens 

 it is coarsely longitudinally wrinkled on the disc ; the elytra are distinctly more 



* There are specimens of this species in the British Museum, and also in the Janson collection, labelled 

 " Guatemala (Scherzer) " ; they are probably from Costa Rica.
