WICKHAM: NEW MIOCENE COLEOPTERA FROM FLORISSANT. 467 
LEPTURA ANTECURRENS Wickham. 
One specimen with counterpart, No. 2,589, 2,590 M. C. Z. (No. 
13,624 and 13,672 S. H. Scudder Coll.). The condition is inferior to 
that of the type and no additional characters can be made out except 
that the present example is a very little larger. 
LEPTURA PETRORUM Wickham. 
Three specimens showing but one side, No. 2,591—2,593 M. C. Z., 
and another with counterpart, No. 2,594, 2,595 M. C. Z. (No. 8,985, 
12,434, 14,164, 9,187 and 9,719 S. H. Scudder Coll.). Only the last 
is in good enough preservation to show the characteristic sharp elytral 
tip. 
LEPTURA INGENUA, sp. nov. 
Plate 10, fig. 2. 
Form moderately stout. Head badly crushed but evidently rather 
large. Eyes not definable. Antennae slender, and, as preserved, 
| reaching well behind the middle of the elytra. Prothorax also badly 
damaged by crushing, of a lighter color than the head, apparently 
reddish or yellowish. Elytra hardly at all tapering behind, surface 
coarsely and deeply, moderately closely punctured at base, the sculp- 
ture becoming finer posteriorly, fading out near the apices which are 
separately rounded, each with a longitudinal slightly oblique pale vitta 
showing on the darker background. Legs wanting. Length, 7.60 mm. 
_ Deseribed from one specimen. | 
Type.— No. 2,596 M. C. Z. Florissant, Col. (No. 6,382 S. H. 
Seudder Coll.). 
Judging from the remains, this is a lepturid beetle of rather broad 
build. The elytral coloration is like that of the recent Leptura vibex 
of the eastern United States. Probably the antennae were pale or 
reddish like the prothorax, or perhaps a little darker. 
| PROTIPOCHUS, gen. nov. 
_ Form approaching that of Ipochus. Head nearly as large as the 
prothorax. Antennae (with only ten joints preserved) reaching about
