joint is very small and frequently needs careful examination for de- 
tection. Quite possibly the fossil represents a genus in a transition 
stage, where the reduction of this joint and the increase in size of the 
third is not yet pronounced, but I do not care to separate it from 
Collops upon this rather dubious character. Compared with 0, 
priscus, the present species is considerably larger, the elytra being 
1 mm. longer, and apparently much less hairy. The lines on the 
elytra are probably wing veins showing through. Three other speci- 
mens, assigned here after the above description was written, all have 
the upper surface of the body better preserved, although the append- 
ages are poor. These additional examples, No. 2,513-2,515 M. C. Z. 
(No. 8,503, 10,710, 14,319 S. H. Scudder Coll.), indicate that the head 
and prothorax are rather shining, the elytra more strongly so, elytral 
surface finely irregularly punctate and distinctly hairy. 
CLERIDAE. 
ENOCLERUS FLORISSANTENSIS, Sp. NOv. 
Plate 5, fig. 8. ) 
Form moderately elongate. Head large, as wide as the pronotum, 
sculpture nearly effaced but what remains indicates it to have con- 
sisted of a fine punctuation. Prothorax broader at apex than at base, | 
widest well in front of the middle, sides, judging by the better pre- 
served one, gently arcuate, base with a fairly well-defined collar or 
constriction, surface with poorly defined punctuation and with traces: 
of hairs. Elytra narrow in the humeral region, humeri rounded, 
surface obscurely punctate and hairy with a few traces of fine lineation, 
apices broken off. Legs only fairly stout. Length of fragment, 
9 mm.; in life probably about .75 mm. more. 
Described from one specimen in somewhat unsatisfactory Se all 
tion. 
Type.— No. 2,516 M. C. Z. Florissant, Col. (No. 9,889 5. H. 
Seudder Coll.). 
The relatively narrow humeri give this insect somewhat the’ 
aspect of the recent FE. rosmarus but the fossil is much greater in 
size. The clothing of hair is poorly preserved and visible only in 
spots. The punctuation is not well enough defined for accurate 
description. |
