532 Mr, T. Vernon Wollaston 07i the 
hairs beneath, and (instead of being on the ordinary pseu- 
dotetramerous type) strictly ybMr-jointed. Its sculpture 
is very peculiar, the punctures (which are lighter towards 
the apex of the eljtra) being exceedingly large and few in 
number (somewhat after the fashion of what obtains in 
07tycholips); its rostrum (as in Alaocyha and Lipom- 
mata) is appreciably, and gradually, narrowed in the 
middle ; its surface, although appearing at first sight to 
be quite bald, will be seen beneath a high magnifying 
power to be studded (at any rate behind) with a few short 
bristles ; and its legs are eminently fossorial, and greatly 
incrassated, — the triangularly expanded tibia3 being deeply 
scooped-out, or emarginate, towards their external angle, 
the excavation being more or less filled-up, or pectinated 
(at any rate in the posterior ones), with strong cilii^, or 
bristles. Its antennae (which are elongate, and almost 
terminal as regards their insertion) have the second joint 
of their funiculus perceptibly, though slightly, longer than 
those which follow it, and their club excessively large, 
abru]:)t, and distinctly annulated ; and its tarsal claws are 
considerably developed. The concave, or longitudinally 
impressed, structure, also, of its first and second abdominal 
segments shoidd be noticed ; but this I think has been 
made too much of as a jieculiariti/ , — since the same feature 
exists (more or less expressed) not only in Alaocyha, but 
likewise in several genera of the Pentartlirides, such as 
Amanroi'rliiwis, Micro.rylobius, Acantliomerus, and Lam- 
prochrus ; and we also find it in Cotaster, of the true 
Cossonides. In no genus, however, that I have yet 
examined, is the concavity so deep, and so well defined, 
as It is in Raymondionymus. In their modes of life the 
species oi Raymondionymus seem to be in entire accord- 
ance with the members of the present curious subfamily, — 
their com])resscd, dilated, setulose, apically unarmed tlblas 
indicating fossorial habits ; whilst their total freedom from 
eyes would tend still further to imply a partially subter- 
raneous propensity. And it is not surprising therefore 
that the few which have hitherto been brought to light 
(])rincipally in the south of France) should have been met 
Avith In such situations as beneath stones deeply Imbedded 
in the soil, within crevices of clay, and in the nests of 
ants. I should add that the particular species from which 
my diagnosis Is compiled, and for a type of which I am 
indebted to John Gray, Esq., is the R. Marqucti, Aube, 
from Narbonne.
