The Beetles of the Moorlands 



white, i.e., pale legged Anchomenus), Fig. n, Plate V. 

 This is a rather larger species than the A. dorsalis we 

 have already taken, nearly 8 mm. long, shining brownish 

 black with the extreme edges of the elytra paler, very 

 pale yellowish legs, antennae, and palpi, the thorax 

 rather longer than wide, rounded at sides and much 

 narrowed behind, with the base strongly punctured, and 

 elytra with distinct striae but unpunctured. This is 

 usually a very abundant beetle along the margin of these 

 upland streams, half a dozen of them often lurking 

 under one stone. 



Another Anchomenus not quite so gregarious we shall 

 also probably encounter ; this is a much more brightly 

 coloured insect about the same size called Anchomenus 

 parumpunctatus (the slightly punctured Anchomenus), 

 Fig. 10, Plate V. ; the head and thorax are usually a 

 shining metallic green and the elytra coppery or purple, 

 equally bright and shining, but some specimens are very 

 much brighter than others, and occasionally individuals 

 occur almost black ; the thorax is more equally rounded 

 at the sides and not so much arrowed behind than is 

 that of A. albipes, the elytra are similarly striated with 

 three or four large punctures scattered over their surface, 

 antennae black, as are also the legs with the tibiae (second 

 joint) lighter. This is like albipes, a widely distributed 

 beetle in the shingle at the margin of streams and rivers 

 all over the country. Then there are four species of 

 Bembidium which we should find either here or under 

 shingle, somewhere else along the course of the stream. 

 These species resemble each other very much ; they are
