2189. NEW FOSSIL BEETLES FROM FLORISSANT— WWKHAM. 471 



but very finely alutaceous. Legs moderate or rather short. Abdo- 

 men, as far as shown along the side, nearly smooth. Length, 4.35 mm. 



Type.— C&t. No. 63451, U.S.N.M. 



Represented by a beautiful specunen, preserved m reverse so that 

 the pmictures above described appear as granules. The form, size, 

 and position of the eye, structure of abdominal segments and, to a 

 less degree, the elytral pmictuation are very similar to the cor- 

 responding features in the recent P. submetallicus from the southwest- 

 ern United States. However, the fossil is without scales and is 

 much more closely pmictate on the head and pro thorax; it may be 



generically distmct. 



Genus TYCfflUS Schonherr. 



TYCHIUS FEROX, new species. 



Plate 39, fig. 5. 



Form fairly elongate. Head with the forehead well arched and 

 rmming into the rostrum without a break, surface vaguely but closely 

 and rather coarsely pmictured. Rostrum slightly curved, moder- 

 ately thick and short, punctured like the head but not striate, scrobes 

 about straight, directed beneath the eye which is elliptical and 

 longitudmal. Antennal scape and funiculus about equal, club oval, 

 gradually formed. Pro thorax about twice as high as long, back 

 scarcely arched, surface closely, more or less confiuently and, rela- 

 tively to the size of the insect, coarsely but only fairly deeply punc- 

 tured, more strongly than the head. Elytron with the margin not 

 very well preserved and the apex apparently a little distorted, about 

 five times as long as the prothorax, surface moderately deeply 

 striate, the striae with distant, not very well marked, elongate punc- 

 tures, mterspaces visibly convex and practically smooth. Beneath, 

 the pectus is pmictate similarly to the pronotum but less strongly, 

 abdomen nearly smooth. Legs of moderate length, the middle and 

 hind femora very strongly dentate, their tibiae slightly bent at base. 

 Length, as preserved, from vertex of head to elytral apex, 3.90 mm. 



Tijpe.—Csit. No. 63452, U.S.N.M. 



Described from one specimen. In form and general appearance, 

 this beetle is like the Florissant fossil T. evolatus and I think the two 

 are likely enough congeneric m spite of the difference in the thighs 

 (which ai-e unarmed in T. evolatus) since the modem species of 

 Tychius may have the femora either dentate or mutic. 



Genus BARIS Germar. 



BARIS PRIMALIS, new species. 



Plate 39, figs. 6, 7. 



Form moderately stout. Head small, relatively coarsely, moder- 

 ately deeply and closely pmictate. Rostrum nearly straight, 

 punctate, more strongly and coarsely than the head, and striate,
