Of!0 i November, 



tween 2000 and 3000 feet, at the middle of June ; it was rather novel 

 to me to see these insects flying about bi-iskly in the hot sunshine and 

 running vigorously over stones, as in the Carluke district the species 

 occurs by the Clyde in March and April, usually latent under stones, 

 and hitherto I have never seen it on the v^'ing. Perla maxima, Scop., 

 was frequent under stones at the river Lochay at beginning of the 

 month ; the examples were not large, and the ^ was of the ordinary 

 short-winged form found in North Britain. Isogenus nuhecula, Newm. : 

 a very few short-winged females (length of fore-wing, 7^-8 mm ) were 

 taken on June 28th at Lochan ua Lairige. Chloroperla grammatica, 

 Poda, was common and apparently normal, and the two species of 

 Isopteryx, which I determine tripunctata, Scop., and torrentium, P., 

 also call for no special remark. Tceniopteryx sp. : similar to that re- 

 corded from E-annoch (Ent. Mo. Mag., loc. cit.) as T. trifasciata, P. ; 

 it is, however, quite different from the true trifasciata which does 

 occur at Eannoch, but in April, not in June ; the species now before 

 me is almost certainly undescribed, although it has been known to, and 

 held distinct by, Dr. Kis for some years. Four species of Nemoura — 

 variegata, Oliv., inconspicua, Pict., cinerea, Oliv., and camhrica, Steph., 

 complete the list of species of which examples have been kept. 



The Ephemeridcd and JPsocidcB were almost entirely neglected, and 

 the Planipennia were also insufiiciently attended to. SialidcB were 

 abundant ; the only example preserved, a small ? from Lochan nan 

 Damh, seems to be S.fuliginosa, Pict. The genus Hemerohius was 

 represented by five species : H. orotypus, Wall., H. marginatus, Steph., 

 H. micans, Oliv., H. subjiebulosus, Steph., and H. nervosus. Fab. Pan- 

 orpcd were swarming on the lower grounds, and they also ascended 

 the hill sides to a considerable height ; they all seemed to belong to 

 various forms of P. germanica, L., with the exception of one $ P. 

 communis, L., a species certainly not common in Scotland. 



Excepting the Limnophilid forms peculiar to standing waters, 

 Trichoptera as a whole were numerous, both as individuals and species. 

 The following list includes most of the species noticed. 



Phn/qanea striata, L , was common at Lochan nan Damh ; the 

 examples were smaller and darker than the normal form. P. ohsoleta, 

 McL., began to appear at the end of the month in the same locality. 



The only representatives of the genus Limnophilus were a few 

 odd specimens of L. centralis, auricula and sparsus. 



Stenophylax steUatus, Curt., was common by the Lochay ; of *S'. 

 infumatus, McL., a single ^ taken at a small burn was more like the 

 Clvdc than the dark Raunoch form.
