152 TERTIARY RHYNCHOPHOROUS COLEOPTERA. 



Tribe DRYOPHTHORIN I. 



This tribe has been recognized in a fossil state only in America, where 

 in onr western Tertiaries at Florissant two species oi-.cnr, each referred tu a 

 distinct and extinct genus.

Many, probably seven, Joints in the I'unicle of the antenna' Spodotrihiix. 



Few, not more than three, joints in the funicle of the antenna' Litliophthorus. 



SP0D0TRIBU8 (a7ro66?, TpiftcS), gen. nov. 



This insect, which seems to belong in the l)r\<)])]it]iorini, differs from 

 either of tlie groups included therein by Le Conte and Horn. The ineta- 

 sternum is a])})areutly long and the fnnicle of the antenna? is corapo.sed of 

 numerous, probably seven, joints; the ej'es, too, are situated almost upon 

 the beak, and are composed of relatively few lenses, bitt are not prominent, 

 and the head has the slightest possi)>le constriction behind the eyes, a little 

 in advance of the middle. The body is elongate. The head is of excep- 

 tionalh' great length, though only half as long as high, subcorneal, with 

 rounded contours; the lieak is as long as the jjrothorax, moderately stout, 

 equal, and very gently curved; the antenna? are inserted at three-fifths the 

 distance from the base, have a slender scape reaching nearly to the eyes, a 

 fuuicle of apparently seven, so far as can be seen equal and quadrate, joints, 

 together as long as the scape, and an elongate oval club, several times 

 longer than l)road and fully twice' as broad as the funicle; the eyes are rather 

 small, short oval, obliquely transverse, the front margin overlapping the base 

 of the beak. The prothorax is cylindrical, even, hitiher than lono- • the leo-s 

 rather slender and not long, and the elytra ridged; the pygidium is apj)ar- 

 ently covered. 



A single species, from Florissant, has come to light.

Both head and beak are very finely granulate, the granulations of the 

 former showing a tendency to a transverse arrangement, and on the sides
