10(5 TimTlARY RHYNCHOPHOEOUS COLEOPTERA. 



broad at base, well rounded, feebly and i-atlier coarsely punctate; eye rather 

 larg'e, transversely ovate; rostrum as long as the head, moderately stout, 

 scarcely arcuate, subacuminate at tip. Prothorax nearly twice as high as 

 long, well arched, feebly punctate, and oblicjuely striate. Elytra obscure, 

 but plainly striate, rather finely and apparently delicately punctato-striate. 

 P^emora rather stout; tibia^ straight, and, especially the fore tibia% rather 

 long.

 body, 2 •75"'".

Tribe MAGDALINI. 



This tribe, composed in America of the single genus Magdalis, is repre- 

 sented by this genus alone in the Tertiary deposits, whether of Europe or 

 America. In Europe two species have been described from Rott; in America 

 one only is found at Florissant. 



MAGDALIS Germar. 



A genus rather richer in forms in Europe than in North America, where 

 we recognize seventeen widely-distril)uted s[)ecies, while a couple of species 

 are found in South America and one in Australia. Heyden describes a couple 

 of species (Magdalinus) from tlie Tertiaries of Kott. I place here a single 

 fossil species fi-om Florissant, which, from the general character of the 

 antemije (though the jointing of tlie funicle is not clear), and the prominent 

 hind angles of the prothorax, as well as by its general aspect, seems to 

 belong certainly in its neighborhood, but which, after all, differs considera- 

 bly froni it in the structui-e of the elytra and the 'early insertion of the 

 antenna?, b}' which the scape is made to reach the very middle of the eye. 

 Both the species described from Rott, and especially 31. deucal'wnis, are 

 much larger than ours, which resembles M. deucalionis rather than the other, 

 but is still well removed from it.
