Kintail again, we have quite another form of scenery — for the 

 country is free from trees ; the hills being, as a rule, bare and 

 rugged, but covered with grass even to the tops. The weather, 

 however, when I was there, was by no means favourable for col- 

 lecting, and thus my list is smaller than it would have been if the 

 weather had been better. 



Of the Tenthredinidae Cimbex sylvarum was found in Strath 

 AfFaric ; Trichiosoma vitellince and lucorum were not rare in most 

 of the birch woods ; and T. sorbi rare in Strath Glass. Abia 

 sericea not uncommon wherever its food-plant, Scabiosa succisa, 

 abounded. A variety of Hijlotoma ustiilata, having the tarsi black, 

 occurred at Strath Glass. Cladius difformis and C. padi, in the 

 same place, and also m Kintail, on Bosa canina, which is the food- 

 plant for both species. Hemichroa ntfa, one specimen near 

 Beauly; H. luridiventris, found everywhere on alder. Nematus 

 Degeeri, abundant in the birch woods in Straths Glass and Aflfaric ; 

 N. stilatus, one or two examples on rowan in Glen Moriston ; N. 

 testaceijjes — the variety with the abdomen beneath testaceous — in 

 Kintail; N. septentrionalis and N. varus, ^ specimen of each, 

 beaten out of the same alder bush in Kintail ; N. ruficornis, 01. 

 (i^ar. fraxini, Hart.), and N. alnivorus (see Ent. Mo. Mag., xi., 107), 

 in Glen Moriston ; N. condiidus, Rutlie ; N. obdudus, Htg. ; N. 

 Kirhji, Dbm., common among grass in all the places visited; 

 N. histrio, Lep., bred from larvae found feeding on Salix aurita, in 

 Kintail. These Kintail specimens are only about half the size of 

 the form I have bred from larvae got near Glasgow ; they agree, 

 however, in coloration, except in being darker, and the apex of 

 the abdomen is, if anything, more acute. N. abdominalis, Fall., 

 in Glen Moriston ; N. luteus and (*?) N. acuminatus, Thoms., in 

 Glen Moriston and Kintail. I am not sure about the last- 

 mentioned form ; it agrees tolerably well with Thomson's descrip- 

 tion of his acuminatus, but it has not the breast black ; from the 

 normal Scotch form of luteus it differs, in its smaller size, in the 

 dorsal surface of the abdomen being black, and in the apex being 

 much more acute. From its occurring in company with the type, 

 it is obvious that it is not a local race ; and, if it be a variety of 

 luteus, it is certainly very interesting to find such a well-marked 

 sub-species (?) subsisting in close proximity with what must be 

 regarded as the parent form. As it scarcely agrees with any of 

 Thomson's varieties of acuminatus, I propose to call the present
