82 TEETIARY RITYNCnOPHOROUS COLEOrTEEA. 



Length, excluding ru.struu), 4"""; rostrum, 1""";, height in middle of ab- 

 d(.imcn, 2""". 



Florissant, Colorado. Four specimens, Nos. 8592, 8702, 9034, 13619. 



The species is named for the entomologist, Prof. John B. Smith, of New 

 Jersey, the latest monographer of the genus in America. 



ApION I'UMILUM. 



PI. V, Fig. 17. 



Viewed from the side, the dorsal aspect is strongly, arcuate. The head 

 is nearly as long as the thorax, rounded conical, the surface transversely 

 striate, beneath the eye |)unctate; eyes circular, not large, lying next the 

 base of the beak, which is porrect and slender, but in the single specimen 

 known is broken a little beyond the base; so far as can be seen it has exactly 

 the aspect of tliat of A. curiosnm. Thorax about half as high again as broad, 

 scarceh' tapering, very gently arcuate above the surface, with large and 

 distant punctures, very different from those of any of the other species. 

 Elytra apparently somewhat larger at base than the })rothorax, very ai-cuate, 

 fullest in the middle, rapidly descending behind, apparently less than twice 

 as long as broad, with coarse, deep i)unctate stnse. Legs obscure. 



Length, excluding rostrum, 2""°; elytra, l-G'"""; height, 1™"". 



This is the smallest of the fossil species. 



Florissant, Colorado. Two specimens, No. 7759, S. li. Scudder; No. 

 2178, U. S. Geological Survey. 



Apion confectum. 

 PI. v. Fig. 3; PL X, Fig. 9. 



A pretty stout species, largest in the middle of the elytra, and behind 

 that rapidly narrowing much as in the group Crassinasuni of Smith, but not 

 cpiite so rapidly. Head consideral)ly higher than long, tapering with 

 slightly arcuate sides, transversely faintly striate, the circular eye at the 

 base of the beak and removed by about its own diameter from the front 

 margin of the prothorax; beak slender, nearly half as long as the body, 

 faintly arcuate, especially next the base where it is also a little tapering.
