 lineatocollis, Oberea oculata {$ and ?), and Cteniopns sulphureus (4), the last

Tachys parvulus, Dej., Sfc, in Cornwall. — During a recent visit to Cornwall 

 (June 19th — July 15th), spent partly at Portscatho, Gerrans Bay (a few miles to the 

 east of Falmouth), and partly in the Scilly Islands and Penzance, a few interesting 

 Coleoptera and Hemiptera were met with, some of which have not been recorded 

 from so far west. The following species were observed on the mainland :* — Tachys 

 parvulus, Dej., sparingly, in three different localities in Gerrans Bay, at the base of 

 the cliffs, in sandy places kept moist by the percolation of freshwater from the high 

 ground above. This minute Tachys was somewhat doubtfully introduced as British 

 by Canon Fowler (Col. Brit.,i, p. 98), upon the authority of a single specimen found 

 at Wallasey in 1884', but subsequently placed by him amongst the doubtful species. 

 It is smaller than any of our other British Caral/idee, and may be easily known 

 from T. bistriatus by the deeply impressed dorsal strife of the elytra, the differently 

 shaped thorax, &c. T. parvulus is not rare in France, occurring both inland and 

 on the coast. Bembidium pa^lidipenne. 111., rarely, in damp sandy places, Gerrans 

 Bay ; -B. rufescens, Guer., common, in a dried-up watercourse, Gerrans Bay. Cillenus 

 lateralis, Sam., sparingly, Portcuil, on the muddy banks of the river running into 

 Falmouth Harbour. Lymnaum nigropiceum, Marsh., singly, on the beach, Port- 

 scatho. Aepus marinus, Strom, and A. liobini, Lab., rarely, Portscatlio and Falmouth, 

 in their usual habitat. Harpalus melancholicus, Dej., in some numbers, at White- 

 sand Bay, Land's End, in the sand ; M. tenebrosus, Dej., and H. ignamis, Dufts., 

 rarely, Gerrans Bay. Amara bifrons, Gyll., and A. aulica, Panz., Whitesand Bay ; 

 A. ovata, Dej., Portscatho ; A. lucida, Dufts., Land's End. Agabus paludosus, F., 

 and Uydroporus lituratus, F., in fresh water pools on the rocks, Portscatho. 

 Ochthehius Lejolisi, Muls. and Key, in abundance in various places in Gerrans Bay, 

 and also at Falmouth, in stagnant, shallow, brackish pools on the rocks occasionally 

 reached by high tides. It seems extraordinary that this insect so long escaped 

 observation in this country, as it occurs apparently in almost every suitable place 

 along these western coasts. The insect readily takes to wing, and must be constantly 

 shifting its quarters as the pools dry up. Many pairs were seen in copulation 

 swimming back downwards, and larvsB were noticed in the same pools. O. bicolon, 



A list of the Scillonian species will be given in a subsequent paper.
