or quite coincident with the strial punctures in regard to number and spacing. 

 Thoracic side pieces strongly, deeply and confiuently punctured, metasternum 

 a little less coarsely and much more sparsely. Abdominal punctures at 

 base a little smaller, shallower and sparser than those of the metasternum, 

 those of the apical segments apparently nearly obliterated. Legs of mod- 

 erate length, the femora all distinctly punctured. Length, from base of 

 beak to elytral apex, 2.20 mm. 



Described from one specimen with counterpart. 



Smaller than any of the Florissant fossil species described 

 by Scudder and of totally different sculpture, which is of a type 

 found in the recent group containing C. hornii, C. nodipennis 

 and C. adjunctus, all from California, Utah and Nevada. I do 

 not find evidence of scales upon the fossil and it may have been 

 nearly glabrous like the first of the above species. The lateral 

 tubercles were probably blunt or small since no indications of 

 them remain. 



The name is given for my friend Dr. Frank E. Blaisdell Sr., of 

 San Francisco, well known for his work on the American Tene- 

 brionidae. 



BAEIS ANTEDILUVIANA sp. nov. 

 (Plate IV, figs. 24, 25). 



Form stout, oval. Head rather small, closely and fairly, coarsely but not 

 deeply punctured. Rostrum gently curved, equal in length to the prothorax, 

 punctate about like the head and striate. Eye of good size, higher than 

 long. Antennae not defined. Prothorax nearly twice as high as long, 

 strongly tapering anteriorly and with well defined collar, back well arched, 

 punctuation a little coarser than on the head, deep and close, each puncture 

 with a small central mark which may be due to a scale. Elytra arched, 

 strongly striate, the striae separated by about twice their own width, each 

 with a row of more or less circular or slightly elongate punctures which 

 are fairly deep and separated by approximately their own longitudinal 

 diameters, interspaces not punctured. Metasternum punctured almost ex- 

 actly like the prothorax, the abdomen much less strongly and deeply. Legs 

 of moderate length, not very well preserved except one belonging to the front 

 pair which has a broad femur and very slightly curved tibia, the latter 

 rather coarsely punctured. Length, excluding rostrum, 2.50 mm. 



Described from one specimen with counterpart. 



In size, this is pretty close to several other Florissant Barids, 

 but may be distinguished from all which approach it in this 

 respect by the combination of characters shown in the relative 

 length and height of the body, the strongly tapering and heavilj^ 

 punctured prothorax and the nature of the striation and punc-
