WICKHAM: NEW MIOCENE COLEOPTERA FROM FLORISSANT. 461 



LlGYRUS EFFETUS, Sp. HOV. 



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 

 condition 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. (No. 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. 

 Scudder 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 17 mm. 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. 

 Scudder 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
