golden-green or purple colour, while others are coppery. They 

 live on various trees, and are sometimes very injurious in orchards. 



Orchestes Alni, Linn., is a red beetle, with two black spots on 

 each of the elytra; it is about one-eighth of an inch long, and 

 is found on alder. The species of this genus are numerous in 

 Europe, and frequent various trees, such as the oak, beech, and 

 willow. 



The species of Cionus, Clairv., are broad and oval, with a small 

 head and pointed rostrum. They are generally found on mullein. 

 C. Pulverosus, Gyll., is a South European species, about one-sixth 

 of an inch long. It is of a brownish grey, with two black spots 

 on the suture. 



Cryptorhynchus Lapathi, Linn., is a conspicuous beetle, about 

 one-third of an inch in length, which is found upon alders and 

 willows. It is a convex dull black insect, thickly scaled with 

 white on the sides of the thorax, and at the base, and for nearly 

 half the extremity of the elytra. Its larva feeds on the pith of the 

 willow, and the beetle appears in autumn, and lives through the 

 winter. This is the only European representative of an extensive 

 genus which is found in all the warmer parts of the world, but 

 is specially numerous in America. 



There are several exotic genera of weevils with small bodies 

 and very long, sprawling, hairy legs, which gives them a curious 

 resemblance to spiders. One of these is Tachygonus Lecontei, Gyll., 

 from North America, a black species with white markings. 



Among the most destructive of the Ehynchophora are the notorious 

 Corn Weevils, Calandra Cfranaria and Oryzce, Linn. They measure 

 about one-eighth of an inch in length. The'former is brown, with 

 red legs and antennae, and the latter is black, with a spot on each 

 shoulder and on each of the elytra, and the border of the latter 

 reddish. They sometimes commit great ravages in granaries, each 

 larva entering a single grain, and devouring the contents. 



Cossonus Linearis, Linn., is a brown or blackish insect, with 

 red legs and antennae, which measures nearly a quarter of an inch 

 in length. It is met with under dead bark. 



Several of the largest of the foreign Curculionidce are closely 

 allied to Calandra. They are generally of a black or reddish- 

 brown colour, and the inside of the legs, and sometimes even the 

 rostrum, is fringed with reddish hairs. Protocerius Colossus, Oliv., 

 is more than two inches in length, and is common in the East 

 Indies ; while the dull black Ehynchophorus Palmarum, Linn., which
