one, contains a number of species which are seriously injiirions to the 

 horticulturist by tlevouring 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 iiaiTow inoiiiliraneous margin. One of the anterior am) middle claw8 cleft. 

 Size below mediiini. 

 B. Elytra stronjjly finrowed, with a small notch at biwe. Thorax impresseil, and hairy: 



Strigoderma, 2 

 B B. Elylra puacto-striate, and without notch. Thorax plain, and nearly or quite hairless: 



Ano.mala, 10 

 A A. Elytra without membrane. Claw.s all simple. Size above medium. 



C Clypeus separated from the front by a distinct suture COTALPA, 5 



C C. Clypeu.s not distinct from the front Pelio.nota, 2 



The StriginUnna 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-l)rown. 



We have two common species of Anomala, the varians and the Inci- 

 cola, of Fabricius, which have been much confounded by authors. Ac- 

 cording to the diagnosis of Burmeister, probably founded, as Ur. Le-' 

 Conte suggests, upon the Fabrician types, the species so common on 

 grape vines at the West, having the elytra faintly striate, and si)otted 

 with black so as to form two imperfect bands, and with the mesosternum 

 only slightly carinate, is the true r«rm/<« of Fabricius, whilst the lucicola 

 has deeply striate elytra without bands, and the mesosternum strongly 

 l)rotuberant. JUit the lucicola usually has the vertex and di.sc 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 Linnwus. The Peliilnota punctata^ Linn., (Fig. 40) is 

 also a large and common si)ecies, 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.
