ZOOLOGY. 



The Rye Chafer {Anisoplia frwticola), somewhat 

 larger than the buckwheat beetle, in other respects 

 very like it, but with a snout-like projection of the 

 thickened skin of the head. Dark bronzy green, 

 whitish on the under side. Wing-covers yellowish 

 brown. On poor sandy soil, on the flowering ears of 

 rye. The beetles gnaw the flowers. 



[The Garden Chafer (Anisoplia horticola) is closely 

 related to the preceding. The grub is very harmful 

 to pastures.] 



Family: Elateridae (Click Beetles). 





^^ 



The Click Beetles (Fig. 74) are longish, of equal 

 breadth all along, tolerably blunt at the hind end. 

 Neck-shield strongly developed. Antennae " serrated," 



i.e. made up of three- 

 cornered joints. 

 Feet five - j ointed. 

 Looking at the 

 under side a spine 

 may be seen on the 

 hinder margin of 

 the pro-thorax (Fig. 

 75, 6), and on the 

 meso-thorax (c) a 

 furrow which re- 

 ceives the spiae 

 when the body is 

 extended, but the 

 spine is drawn out 

 of it if the pro- 

 thorax and meso- 

 thorax are lifted up from anything they happen to 

 rest on (Fig. 76). A skipjack that has fallen upon its 

 back first draws its antennae and legs close to its body, 

 and then bends this in such a way that the head and 

 pro-thorax make an angle with the rest of the thorax
