Middle tibia with the tubercle and groove always largely de- 
veloped. Tarsi simple. 
Monohammitse, Thoms. 
Subtribe 4. Onciderit^. Basal joint of the antennse thickened 
from base to tip ; moderate in size (except in Hippopsitse). 
Middle tibia with the tubercle and groove conspicuous. An- 
terior acetabula angular externally. Tarsi with the claw-joint 
almost always greatly elongated ; claws simple. Body elon- 
gated. 
Oncideritse, Apomecynitse, pt. [Eudesmus, Trachysomus, 
Trestonid)y Hypsiomitse, Onocephalitse^ Hippopsitse, Thoms. 
Subtribe 5. Desmiphorit^. Basal joint of the antennae very 
slender at the base^ abruptly clavate. Middle tibia with the 
tubercle and groove frequently wanting. Anterior acetabula 
angulated externally. Tarsi simple. Antennse filiform, 
rather short, pilose ; muzzle generally very short, and occiput 
very large, prominent. 
Compsosomitse, Desmiphoritse, Apomecynitse, pt. [Hehe- 
stola), Thoms. 
Subtribe 6. Saperdit^. Basal joint of the antennse slender, 
generally thickened gradually from the base. Middle tibise in 
most of the genera wanting entirely the tubercle and groove. 
Anterior acetabula widely gaping externally. Tarsi always 
short; claws very frequently toothed or bifid. Body elon- 
gated ; thorax very generally cylindric, simple. 
Saperditse, Amphionychitse, Tapeinitse, Thoms. 
It is possible that this classification might be improved by 
withdrawing the Hippopsitse from the Oncideritse, and the 
Tapeinitse from the Saperditse, and instituting with them two 
additional tribes. I think it would be difficult, however, to 
form an arrangement which would meet all requirements. Each 
of the subtribes (except the third) will contain several natural 
groups, the definition of which I think it better to leave until 
the whole of the Lamiarise have been passed under review. 
The geographical distribution of the six subtribes is interesting, 
in so far that the first (Acanthoderitse) is almost peculiar to the 
New World, a few species of one genus only having yet been 
recorded from the eastern hemisphere. On the other hand, the 
third (Lamiitse), which exist in great number and variety of 
genera and species in the Old World, is represented in South 
America, at least in the Amazon region, by one genus only, viz. 
Taniotes.
