7 o THE SCOTTISH NATURALIST 



Coleoptera. In the recently issued supplement to that work, G. 

 punctulatus, Thorns., is {teste Lewis) referred to as apparently a 

 synonym of G. rotundatus, Kug., and Dr Sharp, who has kindly 

 examined my specimens, agrees with me in applying this name to 

 them. In 1831, Duncan recorded {Memoirs Wernerian N. H. Soc, 

 vi., 487) Bister rotundatus, Steph., from "near Cramond." This 

 record was repeated in Wilson and Duncan's Entomologia Edinensis ; 

 Coleoptera, 1S34; and again, under the name Saprinus rotundatus, 

 111., Steph., in Murray's Catalogue (1853), with the addition, 

 "Edinburgh and Glasgow." Upon these records Gnathoncus 

 rotundatus, 111., is entered for the Forth and Clyde Areas in 

 Sharp's Catalogue of Scottish Coleoptera. In Fowler's work (vol. 

 iii.) we again recognise them under G. nanneteusis, Mars., which 

 according to Lewis does not occur in this country. Another form, 

 G. nidicola, Joy, has, however, been recently described from 

 England, but my specimens do not seem to be referable to it. 



The publication of Fowler's Supplement enables me to record 

 Micrambe viliosa, Heer, from the Isle of May, where it occurs 

 abundantly on thistles. Dr Sharp, who has recorded the form from 

 Nethy Bridge, Inverness-shire, has seen some of my specimens and 

 confirms the identification. William Evans, Edinburgh. 



Dolichopus caligatus, Wahlb., at Blairgowrie. Since 

 writing my note {Ent. Mo. Mag., January 19 14) recording the 

 occurrence of D. caligatus at Aberfoyle, to which reference is made 

 in the " Editorial " of last month's Scottish Naturalist, I have 

 identified another male specimen taken at Blairgowrie on 8th July 

 last. As this appears to be a rare species, Scottish Dipterists may 

 be interested to hear of a second British example turning up in 

 another locality. 



I take the opportunity of recording two other species of 

 Dolichopus which seem to be rare at any rate I came across them 

 for the first time last June at Blairgowrie, viz. : (1) lepidus, Staeg., 

 2 $ , recorded by the late Mr Verrall from "south of England to 

 north of Scotland," and also included in his list of Arran Diptera, 

 1883; (2) linearis, Mg., 1 o* , a species of which I have not seen 

 any Scottish record. A. E. J. Carter, Monifieth. 



New British and Scottish species of Hydrachnids. In 



the Journal of the Quekett Microscopical Club (Series 2, vol. xii., 

 p. 141), William Williamson records from Oban the following 

 interesting species of Sperchon : S. clupeifer, Piers, new to the 

 Britannic area; S. tenuabilis, Koen. ; and S. papillosus, Sig. Thor,
