WICKHAM: NEW MIOCENE COLEOPTERA FROM FLORISSANT, 485 
have been entirely unable to find any modern insect with antennae of 
the type shown by the fossil. The sculpture is obscure but there is no 
sign of striation or heavy punctuation on any part of the body. 
EPHALUS ADUMBRATUS Scudder. 
The reverse of the specimen which served as the type for Scudder’s 
figure is in the series transmitted to me. It is No. 2,679 M. C. Z. 
(No. 6,469 S. H. Scudder Coll.). 
CISTELIDAE. 
CISTELA VULCANICA, sp. Nov. 
Plate 14, fig. 5. 
: 
Form elongate oval. Head exposed, projecting, a little wider than 
ong, mandibles only slightly prominent. Eyes not well defined but 
what remains indicates that they were rather small and widely sepa- 
‘ated on the vertex. Antennae long and slender, only very feebly 
errate basally, reaching nearly to the middle of the elytra, the second 
oint short, those following the third subequal in length, each more 
han twice as long as wide. Prothorax, as preserved, considerably 
nore than twice as wide as long, sides in rather poor condition but the 
etter preserved one indicates that they were gradually rounded from 
ne broad base to the much narrower apex. Scutellum subcordiform, 
mall. Elytra a little less than four times the prothoracic length, 
yunded at apices. Legs not displayed. Length, to elytral tip, 14 
im. ; of elytron, 10.35 mm. 
_ Described from one specimen with counterpart. 
| Type.— No. 2,680, 2,681 M. C. Z. Florissant, Col. (No. 416 and 
8 5. H. Scudder Coll.). 
‘The entire upper surface is finely sculptured and clothed with 
‘ther close short hairs. The insect looks a good deal like the 
lorissant fossil C. antiqua but has longer and more slender antennae. 
| seems that the two are probably congeneric and may possibly 
!present the two sexes of a single species.
