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. 



DlCERCA 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. 

 Scudder 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. HOV. 



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 descrip- 

 tion. Prothorax much wider than the head, tapering from base to 

 apex, the sides too badly damaged to allow of their shape being deter-
