corresponds more closely with S. cessus of our western states and 
Mexico than with anything else I have seen. The size of the two is 
almost identical and the nature of the sculpture, as well as the arrange- 
ment of the duplicate series is very similar. On account of the fineness 
and indistinctness of the punctuation of the striae and interstices [ 
have not attempted to trace it in detail with the camera lucida except 
in one or two areas where it is particularly well preserved. The courses — 
of the striae are, for the most part, shown on the figure in solid lines. 
The surface is alutaceous throughout, but this minute sculpture may 
be due to the texture of the stone. 
CERAMBYCIDAE. 
PHYMATODES Mulsant. 
A species of this genus (Phymatodes volans) has been described from 
the Florissant shales by Cockerell and Beutenmueller. The one 
which follows is almost too large for a Phymatodes and the reference 
is to be considered entirely provisional. 
PHYMATODES MIOCENICUS, sp. Nov. 
Plate 9, fig. 1. 
Represented by an elytron and a portion of a leg, the structure of the 
latter indicating that the insect does not belong to the Buprestidae, 
where similar elytral color patterns are not uncommon. Elytron 
elongate, In comparison with its width, the humeral region some- 
what prominent, the outer margin sinuate behind the humerus, nar- 
rowing the elytron to about the middle whence it broadens for a short 
distance before narrowing again to the truncate unarmed apex. The 
surface is finely punctate or scabrous, the color dark, (brownish on the 
stone) crossed by two well-defined whitish bands, nearly at right 
angles to the suture, which divide the elytron into three almost equal 
parts. No hairs are visible upon the wing cover, but they show upon 
the tibia which is the only- well-preserved portion of the leg. Length 
of elytron 10.50 mm. Width across posterior band 2.30 mm. 
Described from one specimen with counterpart.
