one, contains a number of species which are seriously injurious to the 
horticulturist by devouring the leaves of both ornamental and fruit 
trees, and especially those of the grape vine. 
The table of genera is as follows : 
A. Elytra with a very narrow membraneous margin. One of the anterior and middle claws cleft. 
Size below medium. 
B. Elytra strongly furrowed, with a small notch at base. Thorax impressed, and hairy : 
STIilGODEHMA, 2 
B B. Elytra puncto-striatfe, and without notch. Thorax plain, and nearly or quite hairless : 
Axomala, 10 
A A. Elytra without membrane. Claws all simple. Size above medium. 
C. Clypeus separated from the front by a distinct suture Cotalpa, 5 
C C. Clypeus not distinct from the front Pelidxota, 2 
The Strigoderma arboricola, Fab., is four-tenths of an inch long ; head, 
disk of thorax, and tip of abdomen blackish ; elytra and broad margin 
of thorax yellowish-brown. 
We have two common species of Anomala, the varians and the luci- 
cola, of Fabricius, which have been much confounded by authors. Ac- 
cording to the diagnosis of Burmeister, probably founded, as Dr. Le- 
Conte suggests, upon the Fabrician types, the species so common on 
grape vines at the West, having the elytra faintly striate, and spotted 
with black so as to form two imperfect bands, and with theiuesosteruuui 
only slightly carinate, is the true varians of Fabricius, whilst the lucicola 
has deeply striate elytra without bauds, and the mesosternum strongly 
protuberant. But the lucicola usually has the vertex and disc of the 
thorax black, and individuals of both species sometimes occur which 
are wholly black. 
The type of the genus Cotalpa is the common goldsmith beetle, Co- 
talpa lanigera, of Limiseus. The Pelidnota punctata , Linn., (Fig. 40) is 
also a large and common species, found feeding upon the leaves of the 
grape vine. It is nearly an inch long, of a bay color, with three black 
spots on each wing-cover. Its larva, as Mr. Riley has ascertained, feeds 
on the decaying roots and stumps of various trees.
