LOBODERES,—AMPELOGLYPTER. 387 
One female. Very like the female of JZ. sulphureiventris, but with the under 
surface almost glabrous, and more coarsely and less densely punctate (the punctures 
on the mesosternal side-pieces large and scattered), the prosternum triangularly 
excavate at the apex, the antennal club larger and longer. Narrower than L. crassi- 
rostris, the intercoxal portion of the prosternum rather convex, the under surface more 
coarsely punctate, the pro-, meso-, and metasternum quite bare. 
RADAMUS. 
Radamus, Kirsch, Berl. ent. Zeitschr. 1875, p. 276. 
Two species from Peru were referred to this genus by Kirsch, one of them being now 
known to extend into Central America. adamus is very closely related to Ampelo- 
glypter, Lec., and both have basally connate tarsal claws; the prosternum, however, 
in the present genus is broadly flattened or concave down the middle, and shallowly 
sulcate or feebly bifoveate in front, and the basal process is greatly developed, so as to 
completely cover the mesosternum.

In this insect the prosternum is narrowly and shallowly sulcate, or feebly bifoveate, 
near the apex and broadly hollowed in the middle, so that the basal portion appears 
to be transversely tumid. ‘The rostrum is stout and strongly arcuate in the male, 
longer, smoother, straighter, and a little more slender in the female. The elytra are 
finely and strongly punctate-striate. The type of 4. atratus, Kirsch, from Peru, is a 
large female of the species described by Solari, who has kindly lent me his types for 
examination. R. wreus, Kirsch, is larger than &. atratus and has the upper surface 
geneous.

_ This genus includes Baridius ovalis, Boh., and various other American forms nearly 
related to Madarellus, but with basally connate or subconnate tarsal claws. The pro- 
sternal excavation is deep and sharply defined, and the basal process is not sufficiently 
developed to completely cover the mesosternum. ‘The meso- and metasternum are 
connate, and the faint transverse suture in A. speculifer is placed in a line with the
