Ben Lomond and Ltjss, 22nd May, 1902 (Mr. Hugh Boyd Watt, 

 Conductor). — The day was unfortunately wet, a soft rain falling 

 almost continuously. Ben Lomond was the programme for the 

 day, but a small party landed at Luss, and the results of their 

 work are included in this report. The remainder of the party 

 " took the hill," a considerable number reaching the top of the 

 Ben (altitude, 3,192 feet). 



Mr. John Paterson reported having seen the Squirrel (Sciurus 

 vulgaris, L.J at Luss, where it is common. Only a very few 

 common birds were seen on the Ben, amongst them a pair of 

 "Whinchats (Pratincola rubetra, L.J Willow-wrens (Phylloscopus 

 trochilus, L.) were singing as high up as the small trees by the 

 burn-side extended, and in the mist, about 1,600 feet up, a Sky- 

 lark was soaring in song. From Luss Mr. Paterson reports the 

 Garden-warbler (Sylvia hortensis, Bech.J, Tree-pipit (Anthus 

 trivialis, L.J and Wood-wren (Phylloscopus sioilatrix, Bech.J 

 with the remark that they may fairly be described as quite 

 characteristic birds of Luss. Longtailed Tits (Acredula rosea, 

 BlythJ were also seen several times. On the lower slopes of the 

 Ben, Mr. R. B. Johnstone captured a Blindworm (Anguis 

 fragilis, L.J, and a bottle full was seen in the possession of some 

 tinkers at Luss, which had been got among the rubbish at the 

 disused slate quarries in Luss Glen, where they abound ; and they 

 seem to occur over all the Loch Lomond district. 



TENTHREDiNiDiE, Mr. A. A. Dalglish reports, were very scarce 

 at Luss, only three species being taken, namely, Tomosthethus 

 fuscipennis, Fall., Pachynematihs caprece, Pz., and Dolerus 

 hcematodes, Schrnk., all swept in marshy ground. 



Among the Aculeata at Luss Formica fusca, Latr., Lasius 

 niger, Linn., and Myrmica rubra, L., race ruginodis, Nyl., were 

 all common. Nomada alternata, Kirby, was taken, and the only 

 other species noticed was Bomhus terrestris, L. 



Lepidoptera — Mr. A. A. Dalglish took the following species 

 at Luss : — Lithocolletis quercifoliella, Z., common at rest on oak ; 

 L. heeg'irieUa, Z., single specimen ; L. alnifoliella, Dup., fairly 

 common on alders; Acalla literaiia, L., single specimen hyber- 

 nated and in poor condition; A.ferrugana, Tr., hybernated and 

 common ; Depressaria arenella, Schiff., single specimen, hyber- 

 nated ; Gracilaria syringella, F., beaten from ash ; Xanthorhoe
