and rudimentary, but occasionally in warmer countries (e.g. Portugal) 

 specimens are found with the wings fully developed : the larva is figured 

 by Fairmaire, Ann. Fr. 1852, PI. ii., Fig. 4 ; it is chiefly remarkable 

 for the very large head, and mandibles, the latter being almost as long 

 as the head and strongly toothed in middle ; the legs and anal appendage 

 are very short, and the cerci of moderate length.

This genus comprises about 400 species, which are almost entirely 

 confined to the cold and temperate regions of the northern hemisphere ; 

 very few species are found south of the equator, and these appear to come 

 from the same regions, as a rule, as the South American Carabi, which 

 are also very few in number, and have a peculiar facies of their own (e.g. 

 C. ckilemis, &c.); in fact as regards distribiition the genera Carabus and 

 Bembidium, almost the largest and smallest representatives of the 

 Carabidae, appear to bear a striking resemblance to one another. The 

 species of Bembidium are almost exclusively confined to damp and 

 marshy localities, being found mostly on the banks of streams and 

 rivers ; although the perfect insect never appears voluntarily to take to 

 the water, yet it will exist for a long time submerged, and many species 

 show considerable agility in regaining dry land ; the larva, however, 

 must often exist for a long time under water, as the habitats of the 

 Beiiibidia are, in many cases, covered with floods for a considerable 

 period during tJie winter months ; the species of the sub-genus Ocys are 

 said to be found under bark of trees ; as far as our species B. rufescens 

 is concerned, I have certainly taken most of my specimens from under 

 bark, but it was in winter from fallen trees at the side of a pond, which 

 Avere full of Anchomeni and other hibernating beetles ; B. g^iinque- 

 striatum I have never found under bark ; it appears rather to frequent 

 moss. The third European species, B. subtile, appears to be now con- 

 sidered a variety of the latter species. 



The genus comprises a large number of subgenera (about twenty are 

 mentioned in the last European catalogue), the species of which often run
