NO. 2189. NEW FOSSIL BEETLES FROM FLORISSANT— WICKH AM. 469 

 Genus SPONDYLIS Fabricius. 



SPONDYLIS TERTIARIUS, new species 



Plate 39, figs. 2, 3. 



Form fairly elongate. Head finely and closely granulate, nar- 

 rower than the prothorax, genae prominent, subspinose. Mandibles 

 rough basally, smooth distally, as in the recent North American 

 S. wpifonnis, quite strongly prominent. Antennae short, joints trans- 

 verse, those of the base and apex wanting or obscured. Prothorax 

 much broader than long, sides nearly straight but apparently not 

 margined, surface sculptm-e coarser and shallower than that of the 

 head. Elytra not very well preserved, the surface showing scarcely 

 any definite sculpture except traces of certain costate markings simi- 

 lar to those of the modern species with which it has been compared. 

 Legs short, tibiae longitudinally carinate. Length, as preserved, 

 from point of mandibles to elytral tip, 18.25 mm. 



Type.— C&t. No. 63448, U.S.N.M. 



No doubt can be held as to the family afiuiities of this beetle. It 

 is evidently a Spondyhd and the first representative of this family 

 from the Florissant shales. The shape of the prothorax and carina- 

 tion of the tibiae point to Parandra, but the apparent lack of pro- 

 thoracic margin, the form of the genae, the sculpture of head and 

 pronotum (as far as preserved) and the elytral costations have led 

 me to refer it, in preference, to Spondylis. When the characters are 

 better known, it may become necessary to erect a new genus for this 

 insect. 



Genus CALLIDIUM Fabricius. 



CALLIDIUM GRANDAEVUM, new species. 



Plate 38, figs. 4, 5. 



Form elongate, subparallel. Head not well dehmited, broad, min- 

 utely roughened beneath. Antennae much shorter than the body, 

 not reaching far beyond the abdominal base, scarcely at all serrate, 

 first joint large, thick, second small, length and breadth about equal, 

 third, fourth, and fifth subequal to each other, each about two and 

 one-half times as long as the second, sixth and seventh a little shorter, 

 eighth to eleventh much narrower and still shorter than those pre- 

 ceding, the tenth not so long as its neighbors. Prothorax broad, 

 sides, as preserved, nearly straight, under surface finely transversely 

 rugose especially along the flanks. Abdomen somewhat distinctly 

 banded with darker. Legs short, not well shown. Length, to 

 abdominal apex, 13.50 mm.; of antenna, from base of second joint 

 to tip, 7.20 mm.
