This weevil is the Cryptorhynchus stigma. It is yellow 
with black spots on the wing-cases. I have obtained 
another fair-sized weevil of the Cryptorhynchus family 
which I am informed is deposited in the same way 
in a larger locust-tree bean found about the foot of 
Roraima. The prevailing colour of this beetle is brown, 
but it has four irregular yellow spots on each of its elytra 
and one on each side of its thorax. Cryptorhynchus is 
made up of two Greek words meaning " hidden-snout/' 
and the name is given to this family of weevils, because 
they are capable of concealing their snout by bending 
their heads downwards and fitting the snout neatly into 
a deep groove on the under surface of the thorax. When 
these inse6ts are disturbed they are in the habit of 
dropping from trees and disguising themselves on the 
ground, where they remain motionless until the cause of 
their alarm has passed away. In this way a long-legged, 
long-nosed weevil can, by drawing its legs under its 
body, and bending its head downwards so as to bring its 
beak into the groove under its breast, in a moment 
assume the form of a pebble or fallen seed. In this dis- 
guise it is often not easily detected even by those 
acquainted with it. 
The Longicornes or long-horned beetles are another 
important se6tion of the Tetramera, their most prominent 
family being the Prionidae (from the Greek prion, a fan) 
or Sawyer Beetles. Probably the most interesting 
species of this genus is the Prionus cervicornis or deer- 
horned sawyer. This is a large flattish beetle varying a 
good deal in size. The specimens which I have seen 
here are from two to three inches long and rather more 
than an inch broad, but I understand much larger speci-
