WICKHAM: new MIOCENE COLEOPTERA from FLORISSANT. 437 

 MiOCYPHON PUNCTULATUS, Sp. nOV. 



Plate 2, fig. 6-8. 



Form elongate, oblong-elliptical. Head of moderate size, eye large, 

 rounded, antennae slender, scarcely serrate, in life reaching only about 

 to the base of the elytra. Prothorax broad, sides arcuate, base evi- 

 dently much broader than the apex. Elytron broad, subtruncate at 

 tip, the surface finely, irregularly, and sparsely punctulate, the punc- 

 tures showing in places some disposition to form rows. Legs in too 

 poor condition for description. Length, 8 mm. 



Described from one specimen. • 



Type.— No. 2,467 M. C. Z. Florissant, Col. (No. 454 S. H.

Although of a puzzling nature, it seems that the family Dascyllidae 

 may be utilized as a place for this insect. The characters which have 

 led me to this assignment are to be found in the form, texture, and 

 punctuation, the coxal structure, and the length of the distal antennal 

 joints. This last feature is not truly characteristic of the Dascyllidae 

 but occurs there, while in most of the other families to which the fossil 

 might at first sight be referred the distal joints are shortened. I do 

 not find any characters sufficiently suggestive to give a clue as to 

 which tribe the msect should enter. 



ELATERIDAE. 



Eucnemis axtiquatus, sp. nov. 



Plate 2, fig. 9. 



Form subparallel, not very slender. Head crushed too badly for 

 description. Antennae with the intermediate joints strongly serrate, 

 approximately one half broader than long. Prothorax distorted, 

 sculpture obscure. Elytra separately somewhat rounded at apices, 

 the sculpture poorly defined and showing only faint traces of striation. 

 Length, to elytral apices, 7 mm. 



Described from one specimen.

This seems to be a member of the Eucneminae and I have chosen
