PANTODINUS.— INCA. 377 



Fam. TRICHIID51. 



PANTODINUS. 



Pantodinus, Burmeister, Handb. der Ent. v. p. 291 (1847); Westwood, Trans. Ent. Soc. Loud. 

 1878, p. 33. 



Burmeister placed this extraordinary and isolated form, in which the head and 

 thorax are cornuted, in the family Dynastidse, notwithstanding its semimembranous 

 mandibles; but Candeze having had an opportunity of examining both sexes, and 

 finding that the clypeus of the female was that of a Cetonid, and the anterior femora 

 exserted, has shown that it belongs to the melitophilous series of Lamellicornia, and 

 that it would be best placed by the side of Inca, in the Trichiidae. The species on 

 which the genus is founded is of extreme rarity.

This well-known genus is one of the characteristic forms of the American Coleopterous 

 Fauna. Eight species have been described, mostly from Southern Brazil; one only 

 extends northwards as far as Mexico.

In all the males I have seen from Mexico and Central America the upper inner 

 carina of the male horns curves towards the inner apical angle, and in all those from 

 South America towards the outer apical angle. This is a more constant difference
