_ This species is distinguished by the deep striation on the middle of each elytron, 
the sutural series of punctures being quite fine and the external series quite obsolete. 
The thorax has a large impression on each side close to the lateral margin, but this 
latter is not at alldenticulate. The species therefore is only closely allied to T. grandis. 
The punctuation of the ventral segments is coarse but not dense. 
We have received only two’ examples of 7. exarata; they are both females and 
possess an extremely indistinct though rather large depression or deplanation along the 
middle of the last:ventral segment. 7. olivacea, Reitter, from Bogota, may perhaps be 
allied to it, but the description differs in many details from our insect.

The very deep channel on the head, the coarse punctuation of this part, its rather 
narrower form, and the slightly more.convex eyes are the most evident peculiarities of 
this species; the sensitive areze on the antenne are large; and the: prosternum behind 
the coxe is a little thicker than in any of the preceding species. Sixteen examples.
