LEAF-CHAFERS. 91 



pale bronze, aud with an irregnlar number of minute white points, and 

 four large white spots on the tip of the abdomen. It is found on Howering- 

 shrubs, and is not uncommon at the west. The 3ur. 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 U. melan- 

 cholica is a much smaller species, almost black, with irregular transverse 

 white lines on the elytra. 



CremasfoiMIus, 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 the mentum 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, which means 

 hanging lip. They have been found under stones beneath wbich were 

 ants' nests ; but their natural history is imperfectly known. 



Osmoderma contains three American and one European species. The 

 0. eremicola, Knoch, is upwards of an inch in length, black, with a 

 faint chestnut tint, and with a smooth shining surface. The 0. scahra, 

 P. de B., is an inch long, black, the elytra being rough, with irregular, 

 coarsely punctured stripe. Triehius, Fab., is composed of a number of 

 closely allied species or varieties, the type of which is the T. lunulatus, 

 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 coxie, and their much shortened elytra. 



Sixth Sub-section, SERRICORNKS. 



AatenniB serrate or saw-toothed. Food-habits 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 antenuie. The serrate antenna is similar to the filiform in being 

 slender, and usually of the same width throughout j but difiers from it in
