150 THE ENTOMOLOGIST. 



as Actecharis Reading i, almost have a claim to the title, as they 

 live on seaweed that is very nearly always immersed. A great 

 number of Coleoptera are habitually found below high-water 

 mark : some are covered by the tide, and we need not wonder at 

 its not injuring them, when we remember what has been said 

 about the beetles found in floods. Many draw back before 

 the tide and return as it recedes : these beetles inhabit the 

 shingle and the layers of rotting seaweed that are so often mixed 

 up with it. Many good Staphylinidse may be found in such 

 localities, as for instance, 7/if/iOc/ians maritima, Philonthus fucicola, 

 Homalota princeps, inuicticeps and pliimhea, Myllcence, Tachyusa 

 uvida and sulcata, Diglossa mersa, Bryaxis Waterhousei, &c. The 

 easiest way to work the shingle beetles is to examine the larger 

 stones and rocks on a warm day, when the beetles may be found 

 coming up from the shrngle and running upon them, and may be 

 taken in numbers. I have taken several of the above-mentioned 

 beetles, and a good many Ptenidium punctatum with them, in this 

 way, in the Isle of Wight. Heaps of seaweed just above high- 

 water mark are very productive, if shaken over paper ; farmers, 

 too, often gather large heaps in the adjacent fields for manure, — 

 these swarm with beetles in warm weather, chiefly Staphylinidse, 

 but Bryaxis Helferi, and good species of Corticaria, Atomaria, 

 and other genera may often be found. 



Collecting under stones on and near the beach is profitable. 

 The curious Lymnceum nigropiceum is only found in shingle : still 

 it prefers shingle under stones, as also do Trechus lapidosus and 

 JEpys. Under the stones well above high- water mark and on the 

 cliff sides many good species of Harpalus occur, and in many 

 places in the south Brachinus crepitans is very abundant. Other 

 Carabidse, such as Polystichus, Drypta, &c., are found not far from 

 the coast. Some beetles, like Broscus, which swarm on or near 

 the shore in many places, are occasionally found far inland, so 

 that in some few cases it is hard to say whether a beetle is exclu- 

 sively a coast species or not. Many Hemiptera, too, are found 

 under and at the sides of stones among herbage close to the 

 shore, as Podops, Mlia, Coreus, and others. 



Sandhills are extremely productive : the rushes and thick 

 grass with which they are usually covered have generally, on a 

 favourable day, a good many species upon them, but sweeping 

 does not produce much, as the grass is so thick and stiff that the
