FOSSIL COLEOPTERA 31 



I might have referred either this species or B. howditchi to 

 Spermophagus vivificatus Scudd., if it were not for the descrip- 

 tion of the antennie in the last named species, where the joints 

 beyond the fourth are said to be much longer than broad, and 

 are so represented in the figure. In the two species of Bruchus 

 the elytra are longer, in proportion to the prothorax. than in the 

 figure of the Spermophagus. 



B. scuDDERi n. sp. (Plate VII, Figs. 7, 8, 11.) Form moderately elongate 

 and more parallel than usual. Head mutilated, but showing signs of very 

 shallow inconspicuous punctuation. Antenna exhibiting the seven proximal 

 joints which are rather strongly serrate, the second joint shorter than the 

 third, the fourth and fifth successively a little longer. The width of all 

 the visible joints is nearly the same, and is about equal to the length of 

 the fourth. The prothorax is distorted to such an extent that I do not 

 care to describe the shape, but it seems to have had no distinct basal lobe 

 and the apex is truncate. The punctuation (relatively to the other fossil 

 Bruchids of Florissant) is strong and moderately coarse, the punctures 

 circular and closely crowded or even occasionally subconfluent towards the 

 sides, more widely spaced and finer along the middle, so as to give the 

 effect of a nearly smooth median line when viewed under a low power. 

 Elytra nearly three times as long as the prothorax, the striae deep but nar- 

 row, with nearly rounded or slightly elongate punctures which are separated 

 by about their transverse diameters. Under surface distinctly and rather 

 strongly punctate over the entire thoracic region, the abdomen much more 

 finely. Hind femur swollen but not visibly toothed, the tibia rather strong- 

 ly curved and carinate, or possibly bicarinate. Length, 3.90 mm. 



Station number 14. One paired specimen, collected by S. A. Eohwer. 

 The type is in the Museum of the University of Colorado. 



Easily recognized, among the Florissant forms, by the elon- 

 gate elytra with strong, sharp, rather finely punctate strife, the 

 moderately strongly serrate antennie, and the strong prothoracic 

 punctuation. 



It is named for the late Dr. Samuel Hubbard Seudder. 



B. HAYWARDi n. sp. (Plate YII, Figs. 4, 5, 12.) Form only moderately 

 elongate. Head weakly, finely and sparsely punctured, the punctuation 

 A-isible only under high power. Eyes not definable. Antennae long, the 

 joints scarcely subserrate, those beyond the fourth distinctly longer than 

 broad, the whole antenna very slender for the genus. Prothorax broad just 

 in front of the base, sides narro'n-ing rapidly to the apex which is truncate, 

 basal lobe rather strong. Pronotal disk with small irregular scattered 

 rather weak punctures, circular or slightly elongate, finer towards the sides, 

 no evidence of median line. Elytra about two and a half times as long as 

 the prothorax, tips rounded and not covering the abdomen, each with ten
