burrows of Collefe.^ daviesana at Favnham, Surrey, was recorded by myself in 

 tbis Magazine (xii, pp. 107, 108). C. populi may therefore be said to be asso- 

 ciated with two genera of bees, Colletes and Dasj/podn. A long account of the 

 life-history, etc., of tlie last-named insect, accompanied by a figure of a New 

 F(U-est specimen, is given by Dr. Sharp in the " Cambridge Natural History," 

 but nothing is said about the Onjjjtophaf/us. — G. C. Champion, Horsell,

The Coast-frequenting Coleoptera of S. Devon and S. Cornwall. — The 

 attention of entomologists is called to a valuable paper on these beetles by 

 Mr. J. H. Keys, entitled "A list of the Maritime, Submaritime, and Coast- 

 frequenting Coleoptera of South Devon and South Cornwall, with especial 

 reference to the Plymouth District '" [Journ. Marine Biol. Assoc, of the United 

 Kingdom, xi, No. 4, pp. 497-513 (May 1918)]. It is, of course, mainly based 

 upon the insects captured by the author in the Plymouth district during 

 the past thirty years or more. He places them under three categories : 

 (1) " Maritime," including the forms inhabiting places covered by the sea 

 for a considerable time during the flow and ebb of the tide ; (2) " Sub- 

 maritime," dwellers at high-tide mark or thereabouts, subjected to occasional 

 wettings by the sea, and the species living in brackish pools and wet places in 

 salt-marshes: (3) "Coast species " living under stones and rejectamenta, as a 

 rule safe from the reach of high tide, and those peculiar to the roots, leaves, 

 and flowers of plants attached to the coast, as we]l as inhabitants of wooden 

 piles on the shore and the denizens of the ooze of freshwater trickles on the 

 cliff's— excepting species equally obtainable inland. The first category includes 

 8 ."^pecies only — Cilhtms, the two Aepus, Actocharis, Arena, Diglotta, Troyo- 

 phloeiis halophilus, and Micralymma ; the second, 54 ; and the third, 89. The 

 writer obviously finds it difficult to draw the line of demarcation between 

 coast and inland forms, and follows, in the main, Fowler's ^'Coleoptera" as a 

 guide. Such insects as Chlaenius vestitus, Pevileptus, Harpalus tardus^, Amara 

 ovata and htcida, Hydroporus lineatus, Atheta triangulum, Quedius umbrinus, 

 Philonthns cruentatus, Oxytehis complanatus, Gcoryssus* Apian schoenherri, 

 etc., etc., seem to be quite at home on the coast, and are included in the 

 author's coast-list, but they are all well known to occur in inland localities. 

 The following species, captured by myself at various times, may be added to 

 Mr. Keys' third category : Ocys harpaloides, commonly, in manj- plices along 

 the south coasts of Cornwall and Devon, comparatively rare inland ; Harpalus 

 discoideus, Dawlish Warren, but really an inland form ; Bledius atricapillus, 

 sparingly, with Dyschiriiis aeneus, in a damp place on the cliffs near Sidmouth ; 

 Lathrohium angustatum, Shaldon and Exmouth, in wet moss on the cliffs, 

 commoner on the coast than inland, in my own experience. Tachys parvulus 

 has been recorded by me from Gerrans Bay, Cornwall, in this Magazine,t but 

 the only locality given is Bovisand. Anchomenus albipes has certainly as good 

 a claim as a coast-species as Chlaenius vestitus, and is so abundant all along the 

 coast, often with Bemhidium saxatile, that it should have been mentioned. 

 Eurynehria complariata, common at Braunton on the N. coast of Devon, so iar 

 as at present known, is absent from the southern beaclies of that county. 

 Ochthebius metallescens, v. poiveri was found freely in June last by myself in a 

 new locality on the cliff-face near Sidmouth. — G. C. Champion.
