52 INSECTS AT noaiE. 



The elytra are rather convex, and their colour is something 

 like that of the thorax, but deepening into violet, which is some- 

 times so dark that it appears to be black. On the shoulder 

 of each elytron is a patch of cream-white, and there is another 

 near the middle, the insect deriving from these white marks 

 the specific title of quadriguttatum, or ' four-spotted.' The 

 spot on the shoulder is usually rather triangular, and that 

 on the middle of the elytron nearly round. 



Our last example of the Geodephaga is the pretty little 

 insect called Bembidium pallidipenyie, which is shown on 

 Woodcut V. Fig. 5. The head and thorax of this species are 

 shining metallic green. The elytra are pale yellow, or straw 

 colour, giving to the insect its specific name of pallidipenne, or 

 ' pale wing.' Across the elytra runs a zigzagged dark band, 

 varying much in different individuals both in depth of colour, 

 in breadth, and in shape. This species occurs chiefly on the 

 coasts of Lancashire, though it is found in other localities. 



The reader will probably understand that when a name is 

 inserted between brackets, it is one by which the insect is known 

 in other systems.
