LE CONTE.—LONG ICORN COLEOPTERA 
The male is much more slender than the female, and the lateral outline of the 
elytra is concave. I found a considerable number of this species at Eagle Harbor, on 
Lake Superior.

tenues, articulo 4‘® brevi. Mentum transversura antrorsum subangustatum, truncatum. Thorax

The form of the head varies in this genus. In some species the sides are parallel 
as in Rhagium, (T. cylindricollis,) in others where the eyes are more prominent, the 
head appears narrowed behind those organs, ( T. cinnamopterus.) The character that 
especially distinguishes this genus, is the position of the terminal spurs of the tibise, 
which, instead of being apical, are situated at the upper end of a deep oblique 
incisure. 
1. T. ScMAUMii.—Niger thorace acute spinoso, utrinque valde constricto, elytris rugulosis, albido-pruinosis 
subparallelis apice oblique truncatis, femoribus medio late flavis. Long. -97. 
This fine species is found in Ohio. I have dedicated it to my friend Dr. Schaum, 
by whom it was presented to me. 
Black, finely pubescent. Head finely punctured, with an impressed line between 
the eyes; labrurn rounded, emarginate. Antennte with the third joint elongate, the 
fourth shorter than the fifth, which is equal to the following. Thorax narrowed in 
front, shining, finely and sparsely punctured, lateral tubercle acute, dorsal line deep. 
Elytra scarcely narrowed behind, finely rugou.s, pruinose with very short hair, tip 
obliquely truncate inwards. Legs black, femora yellow, base and tip black. 
2. T. cvLiNDRicoLLis.— Rufus, supra fuscus, vel niger, subtiliter punctulatus, sericeo-pubescens, capite 
profunde canaliculato, thorace canaliculate, tuberculo obtuse, elytris postice angustatis, apice intus 
profunde incisis. Long. -8.

Varies much in color ; but the base of the femora, the under surface of the body, 
and the tip of the antennae are always rufous. The male is more slender, and the 
antennas are as long as the body. Pennsylvania, Alabama, Missouri.
