CORYMBITES PROPHETICUS, sp. nov. 
Plate T,.hie. 3: 
Form stout. Head in very poor preservation, finely, regularly, 
and closely punctate. Antennae wanting. Prothorax at sides punc- 
tured almost exactly like the head, a little more finely and sparsely on 
the disk, about one fourth broader than long, sides nearly regularly 
arcuate, somewhat more suddenly in front, anterior angles slightly 
acute, hind ones quite strongly so, feebly divergent and -carinate. 
Scutellum oblong. Elytra quite strongly arcuate at sides, apices 
conjointly rounded, finely striate, striae with distinct but not coarse 
punctures which are circular or slightly elongate and separated in each 
series by their own diameters or less. Interspaces broad, flattened 
or nearly so, finely punctulate and distinctly pubescent. Legs 
wanting. Length, from front of head to elytral tip, 10.90 mm.; 
of elytron, 6.55 mm.; of prothorax along median line, 3.00 mm. 
Described from one specimen. 
Type.— No. 2,724 M. C. Z. Florissant, Colo. (No. 13,657 S. H. 
Seudder Coll.). With it is associated, somewhat doubtfully, No. 
2,275 M. C. Z. (No. 11,282 S. H. Scudder Coll.).. Two poor specimens 
from Station 13 and 13B are in the Museum of the University of 
Colorado. 
This is quite surely a Corymbites and is of the same general form 
as the recent C. aereipennis, common in the northern and mountain 
regions of this continent. The sculpture seems not to have been very 
different. The size and outline will distinguish it from all the other 
fossil Florissant species. 
OXYGONUS PRIMUS, sp. nov. 
Plate 7, fig. 6. 
Form fairly stout. Head not well preserved, showing no sculpture. 
Antennae moderately long but the individual joints are not definable. 
Prothorax stout, suborbicular, the sides strongly rounded, apex and 
base subequal, prosternal grooves double, somewhat curved, lobe 
long, front edge quite arcuate and strongly advanced, sculpture fine 
or nearly wanting. Elytron about four times as long as wide, moder-
