40 COLEOPTERA. 



SUB-FAMILY IX. Rutelinw. 



Antennae nine- or ten- jointed, with a compact three-jointed 

 club; front tibiae narrow, with two or three teeth; scutellum 

 variously developed. 



The species of this family much resemble the Melolonthince, but 

 are often more brightly coloured. Some are very destructive, 

 such as the June Bug (Phyllopertha Horticola, Linn.), which some- 

 times swarms on various plants. It is rather less than half 

 an inch long, and the elytra are of a yellowish brown ; the head 

 and thorax are of a brassy green or bluish green. A closely-allied 

 species (Anisoplia Austriaca, Herbst) has committed fearful 

 ravages within the last few years in Southern Eussia. It is 

 rather larger than the last species, and is black, with the elytra 

 either entirely reddish or yellowish brown, or bordered with 

 black, or wholly black. The prettiest European species of this 

 sub-family is Anomala Fitis, Fabr., which is wholly green ; it is 

 rather more than half an inch in length. 



Phyllopertha Firidis, Fabr., is one of the commonest beetles 

 in China ; it is wholly of a bright leaf green above, and coppery 

 on the under surface ; it is about three-quarters of an inch long. 

 Cotalpa Lanigera, Linn., is a handsome North American species 

 about an inch in length. It is of a bright yellow colour above, and 

 pale green, clothed with long white hair, on the under surface. 



One of the largest beetles of this family is Heterosternus Bu- 

 prestoides, Dup. It is a native of Mexico, and is of a rich brown 

 colour. The hind legs are unusually large, the femora being 

 considerably thickened, and somewhat resemble those of a locust 

 when seen sideways. 



SUB-FAMILY X. Dynastince. 



Antennas eight- to eleven- jointed ; club oval, three-jointed ; 

 head and thorax nearly always more or less horned, especially in 

 the males ; elytra covering the tip of the abdomen. 



This sub-family includes many of the largest and most strangely- 

 shaped of the Lamellicornia ; but, with few exceptions, the species 

 all inhabit warm climates, and although a few are met with in 

 South Europe, we have no representative of the group in 

 Britain. The larvae feed on the wood of trees, like those of the 

 Lucanidce and Longicornia. 



Among the smaller beetles of this group, we may mention the
