WICKHAM: NEW MIOCENE COLEOPTERA FROM FLORISSANT. 481 
four sharp subequal denticles. Sternal pieces and first abdominal 
segment finely and closely punctured, the remainder of the abdomen 
less distinctly. Length, to apex of abdomen, 5.50 mm.; to elytral 
apex, 5 mm. 
Described from one specimen with counterpart. 
Type.— No. 2,647, 2,648 M. C. Z. Florissant, Col. (No. 11,269 
and 13,031 S. H. Scudder Coll.). The same species is represented by 
No. 2,649 M. C. Z. (No. 8,428 S. H. Scudder Coll.). 
A fine species belonging, by its antennal characters, with B. exhuma- 
tus and B. scudderi from these shales, though larger than either and 
differing in punctuation from both of them. An interesting feature 
is shown by the exposure of the hind femur which exhibits an arrange- 
ment of tooth and denticles similar to that seen in many recent 
forms. 
BRUCHUS SUBMERSUS, sp. nov. 
Plate 13, fig. 7. 
Form stout, but the body is so much crushed as to obscure the exact 
outline. Head minutely punctulate. Antennae long and slender, 
not serrate. Pronotum with moderate sized round punctures, rather 
crowded near the base and sides, much finer anteriorly. Elytra with 
very large epipleural lobe, strongly striate on the disk and sides, the 
striae becoming evanescent apically, strial punctures hardly wider 
than the striae, those of each row near together. Interstitial spaces 
broad and flat, minutely roughened and finely hairy. Sternal pieces 
and abdomen almost smooth. Hind femur strongly swollen and not 
_ visibly toothed, the tibia curved, with a sharp apical spine. Fore and 
middle legs moderately slender, hairy. Length, as preserved, 5.15 
mm. 
_ Described from one specimen. 
| Type.— No. 2,650 M. C. Z. Florissant, Col. (No. 11,279 S. H. 
Seudder Coll.). 
Probably the best place for this is next to B. henshawi with which it 
agrees in the stout form and rounded elytral strial punctures but the 
Nei ci species is larger, the strial punctures are relatively smaller 
and less conspicuous and the hind femur is very much more expanded. 
ke great development of the epipleural lobe is noteworthy.
