BRITISH BEETLES. 
from the clypeus ; and the club of the antenna three- 
jointed, and alike in both sexes. Their tarsi are 
robust, rigid, prehensile, with the terminal hooks un- 
equal, the outer one being often forked at the apex ; 
and the metathoracic epimera always visible. Iu our 
species the antennas are nine-jointed ; the mesotlio- 
racic epimera do not ascend to the anterior part 
of the elytra ; the clypeus has no projection iu front, 
and the prosternum no elongation behind the coxae ; 
the elytra, also, are lined with membrane, which 
projects behind in the form of a thin rim. 
Phyllopertha horticola, the small “June-bug” 
(Plate VIII., Fig. 1), is often very destructive to 
plants. 
Anomala Frischi, a moderate-sized species, with 
green thorax and reddish-brown elytra, is common on 
sandhills near the coast in many localities. 
The Cetoniina, of which the exotic species are nume- 
rous, large, and beautiful, are here represented by 
a very few (but not inconspicuous) insects. Their 
mandibles and labrurn are hidden under the clypeus, 
the former being composed of an outer horny and 
inner membranous plate ; the antennas are short, 
with ten joints, the club being composed of three ; the 
elytra are somewhat depressed, not reflexed at the 
sides, and leaving the pygidium exposed ; the anterior 
coxae are ovate-conic and projecting; and the hooks 
of the tarsi equal and simple. 
In Gnorimus and Trichius the elytra are not 
sinuated near the shoulder, at the sides, and the meso- 
tlioracic epimera are not visible from the upper side. 
The species of the former occur in all their stages in 
the rotten mould of oak and cherry trees ; and one of
