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. 

 Scudder 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. fiorissantensis and has a differently 

 proportioned head and prothorax. 



HYDNOCERA WOLCOTTI Wickham. 



One specimen, No. 2,518 M. C. Z. (No. 6,385 S. H. Scudder Coll.), 

 less perfect than the type. 



NECROBIA DIVINATORIA, sp. nov. 

 Plate 6, fig. 10-11. 



Preserved in ventral view and showing scarcely any sculptural 

 characters except those of the under surface. Outline similar to that 

 of the recent N. rufipes. Antennae with a three-jointed club, similar 

 to that of recent North American species but with the two joints 

 preceding a little larger in the fossil. Under surface of meso- and
