the name of the typical genus to indicate the place of the species since 
there are no characters shown by the fossil which will serve as a basis 
for separation. The sculpture, though obscure, seems to have been 
rough like that of Sarpedon or Hylochares but the antenna is more 
like that of Eucnemis. 
BUPRESTIDAE. 
DICERCA EURYDICE, sp. nov. 
Plate 3, fig. 1. 
Form fairly slender for this genus but a little less so than would be _ 
inferred from the figure, the left margin of the prothorax and elytron 
being broken off in the fossil. Head of normal size and aspect, sur- — 
face rather finely granulate, eye, viewed from above, oblique. Prono- — 
tum narrowed posteriorly, sides imperfect, surface scabrous, roughened 
with ill-defined longitudinal ridges and grooves. Elytra scabropunc- — 
tate and granulate with scattered irregular indications of raised lines 
and striae, giving the normal appearance of rough sculpture found in 
most of the modern species of Dicerca. The elytral apices are sharply 
pointed. Length, to abdominal tip, 16.20 mm.; of elytron, 10.40 mm. 
Described from one specimen. 
Type.— No. 2,469 M. C. Z. Florissant, Col. (No. 11,649 S. H. 
Seudder Coll.). 
The aspect of this fossil is that of Dicerca but the pointed elytra are 
foreign to my experience with modern species of the genus. In the 
lack of other characters for separation I prefer to leave it here. The — 
form and general features, aside from the one noted, seem much like _ 
those of the living D. spreta. The specimen is in reverse, so that the _ 
granules described represent punctures. |

BUPRESTIS FLORISSANTENSIS, sp. Nov. 
Plate 3, fig. 2. 
: 
Form moderately stout, probably about as in the recent B. aurulenta. | 
Head unnaturally extended, suborbicular, truncate behind, surface (" 
rather finely roughened. Antennae too poorly preserved for deserip- — 
tion. Prothorax much wider than the head, tapering from base to — 
apex, the sides too badly damaged to allow of their shape being deter-_
