14 BEETLES. 



Coppery black above, and easily distinguishable from the last 

 species. It is found in pine woods, running about on the sandy 

 paths. It is the largest species found in Britain, and occurs, 

 among other places, at Bournemouth. 



* G. germanica, Linn., the Small Green Tiger Beetle (Plate I., 

 Fig. 5). This is the smallest species found with us. It is found 

 in fields and grassy places, and unlike the other species, which 

 take to the wing when disturbed, this beetle seeks to escape by 

 running and hiding among tufts of grass. 



Family II. CARABID-ffi (Carnivorous Ground Beetles). 



This is a large family, the members of which have long legs, 

 run quickly, and are carnivorous in habits. Black is the most 

 common colour among them. They hide under stones, moss, 

 and bark, and are very useful, as they keep down the numbers 

 of insects and their larvae in woods, gardens, and fields. The 

 larvse of the ground beetles are just as useful as the beetles 

 themselves ; they live in similar places, and also in dung-heaps. 



Genus Omophkon, Latr. 



Body rounded, head retracted under the prothorax. In the 

 males the first two tarsal joints of the front pair of legs are 

 expanded. 



0. limhatum, Fabr. (Plate I., Fig. 6). This species lives 

 under stones on the sandy banks of streams. It is common on 

 the Continent, but is not found with us. It may be caught at 

 night with the lantern. 



Genus Bletiiisa, Bon. 

 Thorax flat, nearly square, with a distinct border on the 

 sides, and a deep groove near the hinder angles. Eyes only 

 slightly prominent. The only species found in Britain is :
