Hab. Mexico !2,— Brazit 45, Amazon Region °, S. Paulo (coll. Dist.). 
The specimen figured is a typical one from Mexico, and was lent to me for that purpose 
by Dr. Signoret, in whose collection it remains. I have thus been enabled to compare. 
T. achilles, Stal, with T. dwvergens, Walk., and find that they are identical, and not distinct 
as Stal considered 2.

The specimen figured is from Mexico, and was lent to me as typical of A. edessoides, 
Spin. This identification I agree with Mr. Dallas in considering correct ; and therefore 
I have been compelled to place 7. hector, Stal, as a synonym of the same. , 
3. Taurocerus abrupta. (Tab. VIII. fig. 1.)

The specimen figured is the type and only specimen in the collection of the British 
Museum. Mr. Champion has hitherto not met with this species in Guatemala.

This genus is at once separated from the preceding by the lateral lobes of the head: - 
which are longer than the central lobe and acutely produced. But one species is known, 
a widely-ranging Neotropical form, which is found also in the southern portion of the 
Nearctic Region.
