Coleoptera and Hcmiptera in the Highlands. — In the course of about six 

 weeks' holiday in, the Highlands in the autumn of 1919, I took the following 

 Coleoptera, most of which have been examined for me, with his usual kindness, 

 b}' Commander Walker : — Notiophilus aquaticus var. striffifrons and A', palns- 

 tris YiiY.hi/pocrita, botli at about 2000 ft., near Avieraore, in August; Ilonialota 

 (Atheta) inhabilis, one specimen under pine-bark, Nethy Bridge, September; 

 Af/athidiiim rotunilatum, with the preceding; Liodes ,(//«6rrt, abundant under 

 bark of charred pine stumps and log.s, Nethy Bridge, September ; Doidrophayns 

 crenatus, one specimen under pine-bark, Nethy Bridge, September ; with Myclo- 

 philus minor, two specimens. I should also record Sitones grisetts taken at 

 Nairn in October, as the Scotch records of the species appear to be few and 

 uncertain. A tine male of AcantJiocinus aedilis whs brought to me alive by 

 two schoolboys (D. and I. Turnbull) staying at Nethy Bridge, early in September. 

 But Coleoptera generally were scarce and needed patient hunting. Among the 

 Hemiptera taken, it may be worth while to record Erenwcoris 2>lfbeius, one 

 under shingle by Loch an Eileun ; Orthodira nigritia, two specimens in moss 

 at Nethy Bridge; Salda scotica, ho])ping about in the greatest abundance on the 

 shore of Loch in Dorb ; Lygus rubricatus, the dark form, on fir ; and Cori.ra 

 venusta, abundant in Loch in Dorb. I have to thank Mr. E. A. Butler for his 

 kind help in determining some of these. — A. W. Pickakd-Cambbidgk, Balliol

Cryptohypnus sabulicola Boh. in Herefordshire. — Mr. Tomlin, in the Ent. 

 Mo. Mag. vol. li, p. 6 (1916), has recorded my capture of Crijptohypnus sabuli- 

 cola in .July 1914 on the banks of the River Monnow near Pontrilas in Here-
