FAUNA AND FLORA OF NORFOLK : COLEOPTERA. 
Bradycellus oollaris, Payk. The occurrence of this mountain 
species in this county is remarkable; but specimens 
from Mousehold Heath, where it occurred rarely 
in 1883, are identical with northern examples. 
„ similis, Dej. Very common at the roots of Heath, &c. 
Patrobus exgavatus, Payk. Not very common. 
Pogonus luridipennis, Germ. First discovered in Britain by the 
Bev. J. Burrell at Salthouse in 1806, and the 
following paragraph from his pen which accompanies 
Curtis’ plate 47 (Pogonus burrelli, as it was then 
called) seems worthy of reproduction here : “ The 
genus Raptor, confined as it is to three British 
species ( burrelli , Haw ; clialceus, Marsh. ; and 
( vruginosus , Steph., MSS.) is perfectly maritime ; 
the species being all found in the same situation, 
and may be deemed subaquatic ; for in winter and 
a considerable part of the summer the habitat of 
these pretty animals is entirely covered with water, 
which stagnates many inches deep in the low 
places of the marshes after the tide has flowed and 
ebbed. When these spots, which are first formed 
by a casual removal of the oozy soil for agricultural 
purposes, are dried, through evaporation caused 
by the summer sun, the soil cracks in various 
directions ; and out of these cracks when any one 
walks across the place the Raptores dart up 
with swiftness and in great numbers. They are 
principally found in the months June, July, 
August, and September ; and if the weather be 
warm and dry, they may be captured, though 
in less quantity, in May and October. They 
associate with many species of Bembidium, and 
not unfrequently the Cillenum laterale is seen in 
their company. The most manifest habitat of our 
species is at Salthouse in Norfolk, upon the salt 
marshes separated from the German Ocean by 
a high mound of pebbles and other small stones 
rounded by attrition, and through which mound 
the tide penetrates at its highest flow.” Salthouse,
