130 TERTIARY RHYNCHOPHOROUS COLEOPTERA. 
CEUTHORHYNCHUS Germar. 
A prolific genus with a couple of hundred species, almost exclusively 
confined to the Old World. We have, however, nearly twenty species in 
North America, widely distributed. Four species have been found in the 
European Tertiaries and five in the American, almost confined to and 
somewhat characteristic of the Gosiute fauna, only one of the species 
occurring elsewhere. The European species mostly occur at Brunstatt, C. 
obliquus Forster being very close to our C. compactus, but the species from 
Rott bears no special resemblance to any of the American species.

Pl.x1, Fig. 13. 
Head broad but short and not very full, not very finely but densely 
punctate; eyes large, very broad ovate, transverse, midway in height; 
rostrum stout, gently and regularly arcuate, a little longer than the pro- 
thorax, finely and feebly striate. Prothorax without postocular lobes, fully 
twice as high as long, roundly ‘but feebly tapering from the base, beneath 
very full, the surface coarsely vermiculate. Under side of thorax very 
coarsely and somewhat sparsely but distinctly punctate, of the abdomen 
feebly punctate. Elytra with alternate costa and sulci, the latter deeply 
and distantly pierced with more or less longitudinal puncta.
