62 TERTIARY RHYNCHOPHOROUS COLEOPTERA. 
EUDOMUS (evdopos), gen. nov. 
Body stout, less than twice as long as broad. Rostrum as long as the 
head, pretty stout, equal, the tip broadly rounded. Eyes strongly transverse, 
oval, subacuminate, very large, as long as the lateral breadth of the rostrum. 
Scrobes strongly arcuate, passing beneath the eyes. Antenne short, club 
not at all stout, long-oval, the apical as large as the two preceding joints. 
Thorax broader and higher than long, with prominent subangulate ocular 
lobes. Elytra much broader than the thorax at base, with rounded humeri 
and parallel sides. Second abdominal segment longer than the two follow- 
ing, its anterior suture strongly arcuate ; intercoxal process broad, tapering, 
truncate at tip. Metasternal side piece moderately wide, expanded ante- 
riorly by a narrow triangular side process directed inwardly ; mesosternal 
side pieces subequal, the episternum separated from the epimeron by a sin- 
uous suture so directed that the lateral outer margin of the epimeron is 
considerably longer than its posterior margin, the opposite of what is found 
in Kudiagogus. 
This genus evidently falls in the Promecopini in the vicinity of Eudi- 
agogus, but differs from it as from all living genera in the much robuster 
form and larger size, as well as in most of the details of structure given 
above. 
Two species occur, both at Florissant.

Pl. mt, Figs. 2, 4. 
Head, including rostrum, and thorax finely and densely beaded, the 
markings a little coarser and more pronounced on the thorax than else- 
where. Similar markings occur on the under side of the thorax. The elytra 
are considerably less than twice as long as the rest of the body, and have 
punctured, strongly impressed strize, the punctures being circular or scarcely
