WICKHAM: NEW MIOCENE COLEOPTERA FROM FLORISSANT. 461 
LIGYRUS EFFETUS, sp. nov. 
Plate 6, fig. 11. 
Preserved lying partly on the back, so as to give a view of the side 
and a portion of each of the dorsal and ventral surfaces, but the 
- eondition is too poor to allow the sculpture to be described. Head 
small, as usual in this genus. Prothorax short and wide. Elytra 
exhibiting faint traces of striae, whether punctate or not it is impos- 
sible to say. Legs very short and stout, the hind tibiae broad, middle 
ones less so. Tarsal articulation not well defined, but the hind tarsus 
is at least as long as the tibia. Length, 13.75 mm. 
Described from a single specimen with its counterpart. 
Type.— No. 2,576,2, 577 M. C. Z. Florissant, Col. (Ne. 12,025 
and 12,031 S. H. Scudder Coll.). 
By the facies, this should belong with Ligyrus. It is a smaller 
species than L. compositus of these shales, being about equal in length 
to undersized examples of the recent L. gibbosus. Most probably, 
though not certainly, it differed from either of the above in having 
finer sculpture. 
Ligyrus compositus Wickham. 
Two specimens, No. 2,578, 2,579 M. C. Z. (No. 953, 13,614 S. H. 
Seudder Coll.) both poor, probably belong to this species. 
STRATEGUS CESSATUS, Sp. NOV. 
Plate 7, fig. 4. 
Elytron castaneous, finely, sparsely, and irregularly punctate. 
There is a fine sutural bead, a similar exteromarginal one which is 
slightly less pronounced, and about nine fine discal striae, one of which 
is paired with the sutural bead while the others form four double series 
as shown in the figure. These striae are finely and distantly punctate. 
Length 17mm. Width 8.80 mm. 
Described from a single specimen, an elytron only. 
Type.— No. 2,575 M. C. Z. Florissant, Col. (No. 9,047 S. H. 
Seudder Coll.). 
After comparing this elytron with those of a great number of recent 
American and foreign genera, I have placed it in Strategus since it
