Distinguishable from C. prociduus only in the male sex by the small spine-like horn 

 behind the base of the long frontal horn being erect (slightly curved in feebly developed 

 individuals), the same being inclined nearly horizontally in C. prociduus. The other 

 differential characters mentioned by Von Harold prove variable on the examination of 

 a long series, and as there are intermediate examples in Mexican localities, the two 

 species, or forms, would not merit separation if it were not for the difference in their 

 geographical distribution. 



A fully-developed male from Nicaragua is figured. 



PHAN^EUS. 



Phanceus, MaeLeay, Horse Ent. i. p. 124 (1819) ; Lacordaire, Gen. Col. iii. p. 100. 



About eighty species have been described of this fine genus of Copridae, one of the 

 characteristic forms of the American Fauna. As usual, the tropical zone yields the 

 greatest number and variety of species ; but the genus is well represented in the 

 warmer temperate regions both north and south, and shows no failing off there as 

 compared with tropical congeners in richness of colouring. Central America contains 

 a large proportion of species, mostly belonging to one group, and offering less variety 

 of forms than tropical South America.

Very closely allied to P. telamon, Erichs., of Eastern Peru and the Upper Amazons ; 

 in both sexes the outline of the toothed clypeus and the sculpture of the elytra are
