oue, 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 : 



STlilGODEKMA, 2 



B B. Elytra puncto-striate, and without notch. Thorax plain, and nearly or quite hairless : 



Anomala, 10 

 A A. Elytra without membrane. Claws all simple. Size above medium. 



C. Clypeus separated from the frout by a distinct suture Ootalpa, 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 the mesosteruum 

 only slightly cariuate, is the true varians of Fabricius, whilst the lucicola 

 has deex)ly striate elytra without bands, 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 Linnaius. The Felichiota 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. Eiley has ascertained, feeds 

 on the decaying roots and stumps of various trees.
