INSECTA — COLEOPTERA.

The reporter has described two Brontes from Van Diemen’s Land, 
one Dendrophagus, and one Silvanus, as new species (Arch. p. 217). 
Longicornes. — The species of this family, collected by Cuming in the 
Philippine Islands, have been described by Newman, though not with 
sufficient accuracy. (Entomologist, p. 243, 275, 288, 298, 318, 369, 381.) 
From Harris’s observations on the North American Cerambicidce 
(Ins. of Massachus. p. 77), it appears that the larva of the Prionus 
laticollis, Drury, (hrevicornis, F.) lives in poplars ; that of the Steno- 
corns (Cerasphorus) cinctus, Drury, (garganicus, F.) in hickory trees, 
boring through the stem in aU directions ; Elaphidion putator (Stenoc.), 
Peck, is found in the black and white oaks, and according to Peck’s 
observations, the larva lives in the pith of the boughs, and at last gnaws 
through the wood, and undergoes its metamorphosis when lying on the 
ground. Callidium hajulus and violaceum have been brought from 
Europe, and become native to North America. The beautiful Clytus 
speciosus, Say, (Hayi, Griff.) is occasionally destructive to the sugar 
maple, into the wood of which the larva bores ; that of the CL Jlexuosus 
lives under the bark, and in the alburnum of the Rohinia pseudacacia. 
The larva of the Saperda calcarata, Say, lives, like our 8. carcharias, 
in the stems of different species of poplar ; that of the 8. hivittata, Say, 
in apple trees, to which they do great injury, as well as in various 
trees and bushes, but originally it preferred the North American 
Aronice. The larva of the 8. (Oherea) tripunctata lives in the pith of 
the branches of a species of bramble (Rubus villosus), which is cul- 
tivated abundantly for the sake of its fruit resembling the currant. 
Desmocerus palliatus is found upon the elder tree ; the larva lives 
in the lower part of the branches in the pith. The larva of the 
Rhagium lineatum lives under the bark of the pitch fir, which comes 
off by its gnawing, and the tree is destroyed. 
Spinola has published a valuable treatise on the systematic arrange- 
ment of the Prionidoe (Mem. della R. Acad. d. Scienz. d. Torrino. 2, Ser. 
V.) He comprehends, in one large division, all those beetles in which 
the first three tarsal joints are covered beneath with hairy felt, and the 
fourth is very small and narrow, and united to the fifth, as the Curcu- 
lionidoe, Cerambycidce, and Chrysomelidce. This division he separates 
into two groups, either as the prothorax consists of tergum, episterna, 
and prosternum, or only of a single piece, generally of a tergum and 
prosternum. The first group contains the Bruchidce and Halticce (both 
defined as springing, which is not suitable for the former, as all spring- 
ing insects have straight tibiae ; those v,dth crooked tibiae, like the 
Bruchidce^ however much the thighs may be thickened, are not spring- 
ers), the Hispidce, Gallerucidce, Chrysomelidce, and Prionidoe. The 
second group contains the Cerambycidce, Lamia, and Cicrculionidce. 
The Prionidoe are separated from the rest, by the cylindrical anterior
