16 BEETLES. 



Genus Procrustes, Bon. 



La brum with two concavities. Mentum with a broad, obtuse 

 tooth in the middle. Legs long, with the first three joints of 

 the front tarsi expanded in the males. Found in woods. 



P. coriaceus, Linn. (Plate L, Pig. 12). This is a large ground 

 beetle, which is found in many places on the Continent, under 

 stones and leaves in woods, and less frequently in gardens, 

 but is not P)ritish. 



Genus Carabus, Linn. (True Ground Beetles). 

 Most of the species are large and showy, and are remarkable 

 for their bright metallic colours and the very various sculpturing 

 of the elytra. The third joint of the antenna is cylindrical 

 and longer than the rest. Abdomen oval. Pront tarsi of 

 the males with three or four expanded joints. They are most 

 common in hilly districts. 



* C. monilis, Pabr. (Plate I., Pig. 13). Elytra green, blue 

 or coppery. It is common with us, under stones and clods. 



C. ulrichii, Germ. (Plate L, Pig. 14). Elytra very convex, 

 larger than in the two next species. It is found in South 

 Central Europe, where it passes the winter in tree- trunks and 

 under moss. 



* 0. cancdlatus, Illig. (Plate I., Pig. 15). Antennae with 

 the basal joint red. Wing-cases reddish or bronze-coloured, 

 with three longitudinal ridges and long granulations. It is 

 found in May, but is doubtfully British. 



* C. gramdaius, Linn. (Plate IL, Pig. 1). This species is 

 similar to the last, but usually smaller and with black antennae. 

 It is common, and is found in swampy places. 



C. auratus, Linn., the Gold Beetle (Plate IL, Pig. 2). The 

 spaces between the green longitudinal ridges of the elytra
