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. 

 Scudder 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 

 present species is larger, the strial punctures are relatively smaller 

 and less conspicuous and the hind femur is very much more expanded. 

 The great development of the epipleural lobe is noteworthy.
