WICKHAM: NEW MIOCENE COLEOPTERA FROM FLORISSANT. 449 
ENOCLERUS PRISTINUS, sp. NOV. 
Plate 5, fig. 9. 
Form moderately elongate, subparallel. Head large, apparently 
greater in size than the prothorax, minutely scabrous and with a few 
rather long blackish hairs, probably the remains of a much more 
thickly disposed vestiture. Eyes of good size. Only one antenna is 
shown, and that in poor preservation, but the external joints are seen 
to be moderately thickened forming a gradual club. Prothorax 
strongly transverse, not very much narrowed posteriorly, sides feebly 
arcuate, anterior impressed line distinct. The sculpture is poorly 
preserved but what remains indicates a fine reticulation or scabrosity. 
Elytra a little more than twice the combined length of the head and 
-prothorax, apices bluntly rounded, sculpture obscure but traces are 
_to be seen of vague sulcations or costae. Legs not very long and rather 
slender. Length, as preserved, 8.15 mm.; to elytral apices, 6.85 mm. 
Described from one specimen. 
Type— No. 2,517 M. C. Z. Florissant, Col. (No. 12,245 S. H. 
Seudder Coll.). | 
| The characters shown are hardly sufficient to allow of comparison 
with recent American forms but I think that the fossil represents an 
insect of about the build of small specimens of E. moestus. It is 
only about two thirds as long as E. florissantensis and has a differently 
proportioned head and prothorax.

One specimen, No. 2,518 M. C. Z. (No. 6,385 S. H. Scudder Coll.), 
less perfect than the type.

Plate 5, fig. 10-11. 
Preserved in ventral view and showing scarcely any sculptural 
sharacters except those of the under surface. Outline similar to that 
: the recent NV. rufipes. Antennae with a three-jointed club, similar 
(0 that of recent North American species but with the two joints 
vreceding a little larger in the fossil. Under surface of meso- and
