 hibernate. The larva has the general form of that of Poecilus. 

 - The species of Harjpaliis are large, 

 with a very square prothorax. H. 

 ^f caliginosus Say (Fig. 374) is bene- 

 ficial in eating cut-worms and other 

 injurious larvte. Fig. 375 represents 

 a larva supposed to belong to this or -^ 

 an allied genus. The blind Anoph- 

 tJiahnus Tellkampfii Erichs. from the 

 Mammoth Cave, has no ej^es, while 

 the legs are very long, especially 

 the narrow fore tibiae ; but in Tre- 

 cJius, which is closely allied to the blind Cave Beetle, 

 the eyes are as large as usual, and the legs stouter.

 closely allied to Bembidium, is known to seize 

 the beach-flea, Gammarus, and devour it.
