The form, size, thoracic outline (especially the shape of the 

 base), the proportions of the abdominal segments and the 

 vestiture all point to this generic assignment. The sculpture- 

 seems to have been finer than that of any of the recent North 

 American species with which I am acquainted, and this char- 

 acter will separate it from the fossil A. sopitus. 



Telephorus Schaff. 



T. humatus n. sp. (Plate I, Fig. 2). Form subparallel, rather 

 narrow. Head crushed so as to appear excessively large, particularly 

 since the basal antennal joints are thereby merged with the genae. 

 Eye moderately large, rounded. AntenricE equal to a little more than 

 one-half the body length, first joint not distinguishable, second small,, 

 third shorter than the fourth, remainder subequal in length, all except 

 the distal three with the inner angles produced so as to appear moder- 

 ately serrate. Prothorax transverse, sides and apex rounded. Scutel- 

 lum of nonnal size, triangular. Elytra four times the length of the 

 prothoracic median line, rounded at apices. Legs rather short. Lengthy 

 7.50 mm.

In form and size this insect resembles the recent T. bili?ieatus 

 quite closely. The sculpture is of the fine alutaceous type 

 common in the genus. 



/ Trypherus Lee. 



T. aboriginalis n. sp. (Plate I, Fig. 3). Form similar to that 

 of the recent T. latipennis. Head a little distorted, but evidently 

 of moderate size. Antennas slender, filiform, the joints net serrate, 

 but too poorly preserved to describe as to their relative lengths. Pro-- 

 thorax about as wide as the head, transverse, apex narrower than the 

 base, sides moderately strongly rounded. Elytral length equal to 

 twice the prothoracic width, apices narrowed, but rounded, sculpture- 

 strongly scabrous. Abdomen with several segments exposed beyond 

 the elytral tips, without visible terminal appendages. Legs wanting, 

 except one femur, which is rather slender. Length, 8.75 mm.

 6527. 



There is little doubt that this insect is closely allied to- 

 Trypherus if not an actual member of the genus. It has the 

 size, form, sculpture and general appearance of the recent 

 T. latipennis, common in the eastern half of North America..
