LEAP-CHAFERS.

pale bronze, and with an irregular number of minute white points, and 
four large white spots on the tip of the abdomen. It is found on flowering 
shrubs, and is not uncommon at the west. The Mir. Inda, Linn., is our 
most common species of Cetonia. It varies in length from half to two- 
thirds of an inch; it is of a yellowish-brown color, the elytra sprinkled 
all over with small irregular black spots. It is sometimes troublesome by 
burrowing into ripe fruit, and also by feeding upon sweet corn in the 
milk. The larvae, probably, like those of other known species, live in 
rotten wood, as the perfect insects are often seen flying over chip-yards, 
probably in search of a convenient nidus for their eggs. The E. melan- 
cholica is a much smaller species, almost black, with irregular transverse 
white lines on the elytra. 
Crcmastochilus , Knoch, contains a considerable number of rather rare 
species, half an inch or a little less in length, of a deep black color, 
sometimes with a few small white marks on the elytra. The mouth is 
peculiarly constructed. The clypeus or anterior margin of the head 
is thickened, and turned up, and thementuin is much enlarged, project- 
ing forward so as to almost close the oral cavity, and its sides hang- 
down like two curtains, which suggested the generic name, w hich means 
hanging lip. They have been found under stones beneath which were 
ants’ nests ; but their natural history is imperfectly know r u. 
Osmoderma contains three American and one European species. The 
(). eremicola , Knoch, is upwards of an inch in length, black, with a 
faint chestnut tint, and with a smooth shining surface. The 0. soabra, 
P. do B., is an inch long, black, the elytra being rough, with irregular, 
coarsely punctured strim. Triehius, Fab., is composed of a number of 
closely allied species or varieties, the type of which is the T. lunula tun, 
Fab., a very common and pretty insect, often seen upon flowers in our 
gardens, basking in the hot sunshine, but readily taking to flight. It 
is a little less than four-tenths of an inch in length ; the thorax dark 
brassy-green, the elytra more or less reddish on the disc, widely bor- 
dered with black, and with two transverse white marks on the side of 
each elytron. The under side is densely hairy. 
Valgus contains three small brown species, densely covered with mi- 
nute whitish scales. They are easily distinguished by their distant pos- 
terior coxa 1 , and their much shortened elytra. 
Sixth Sub-sectiou, SERRICORNES. 
Antcnme serrate or saw-toothed. Food-liabits various. 
This sub-section of beetles with five-jointed feet is primarily distin- 
guished, as its name implies, by the serrate or saw-toothed character of 
the antennae. The serrate antenna is similar to the filiform in being- 
slender, and usually of the same width throughout; but differs from it in
