der Coll.). 
I have placed this fossil in Polemius rather than in Telephorus 
chiefly on account of the heavy antennae. The posterior half of the 
elytra is darker than the anterior but I am not at all sure that this is 
due to any difference in color in the living insect, it seems more likely 
the result of scaling off of a portion of the metamorphosed chitin 
when the stone was split. 
TRYPHERUS ABORIGINALIS Wickham. 
Two specimens, one with counterpart, No. 2,503-2,505 M. C. Z. 
No. 8,586, 8,499 and 8,651 5S. H. Scudder Coll.). They show no 
important characters not brought out in the original description.

Form, in life, apparently similar to that of the recent C. bipunctatus | 
but as preserved the abdomen is greatly distended, presumably by. 
maceration. Head with rather indistinct outline, sculpture not dis-_ 
cernible, antennae short, stout, first joint elongate, second much longer 
and distorted by the production of the inner apical angle, the third, | 
fourth, fifth, sixth, and seventh, subtriangular, moderately serrate, 
eighth damaged, remainder not definable. Prothorax about as long 
as the head, no defined sculpture. Elytron nearly smooth but with a. 
sparse covering of rather long black hairs. Legs slender. Length, as 
preserved, 5.70 mm.; of elytron, 3.60 mm. 
Described from one specimen with counterpart. 
Type.— No. 2,506, 2,507 M. C. Z. Florissant, Col. (No. 8,140, 
and 9,307 S. H. Seudder Coll.). 
The form, vestiture, antennae, and abdominal segmentation all. 
point to the above generic reference. Measured from the front of the | 
head to the elytral apex, this insect about equals in size the living 
North American C. hirtellus which occurs from New Mexico to Nevada, | 
Washington, and the Saskatchewan.
