WICKHAM: NEW MIOCENE COLEOPTERA FROM FLORISSANT. 463 
The specimen indicates a longicorn beetle of a rather uncommon 
type of coloration, though approached more or less closely by recent 
species of various tribes. It seems worth while to give a specific name 
to the insect on account of its colorational interest. The pattern is 
almost a copy of that of the recent African Ceroplesis bicincta. 
ELAPHIDION EXTINCTUM, sp. nov. 
Plate 8, fig. 7. 
Form stout. Head smaller than the prothorax, the jaws fairly 
strongly projecting, front finely, transversely, subrugosely punctu- 
late. Eyes not defined. Antennae only obscurely exhibiting the 
proximal joints, the first stout, second apparently short, third long. 
Prothorax strongly transverse, sides not perfect but apparently 
moderately arcuate, surface rather finely but very closely and fairly 
deeply punctate, the punctures in front of the middle more or less con- 
fluent with a tendency to form transverse rugae, an impunctate area, 
probably a callosity, on each side. Elytra bluntly rounded at apex, 
more finely and sparsely punctate than the prothorax and with scat- 
tered, short, blackish hairs. The only leg shown is fairly slender. 
Length, from apex of jaws to that of abdomen, 11.35 mm.; of head and 
prothorax, 3.75 mm.; of the right elytron, 6.45 mm. 
Described from one specimen with counterpart. 
Type.— No. 2,582, 2,583 M. C. Z. Florissant, Col. (No. 11,780 
and 12,034 S. H. Scudder Coll.). 
By allowing some latitude of definition, this may have been an 
Elaphidion-like form of the same general appearance as the recent 
E. moestum but with callosities similar to those of the more typical 
species of the genus. Too little is shown to make the generic reference 
at all certain. 
STENOSPHENUS PRISTINUS, sp. nov. 
Plate:'9, fig. 2. 
Form elongate. Head large, longer than the prothorax. Antennae 
about as long as the entire body, basal joint large, second small, third 
longer than the fourth which is subequal to the fifth and to the sixth, 
remainder not definable. The sixth joint seems to show an apical 
spine but the margins of all the articles are poorly preserved, so that
