4g ' February, 



Stenophylax infumatus, McL. — The day we arrived we were fortunate enough 

 to fall upon what was probably the original locality whence Mr. McLachlan procured 

 his typical specimens — a deep-cut moor stream overhung by heather and bog myrtle. 

 There the insects were rather common, mostly S , but only to be found after diligent 

 search in a manner which experience alone can teach, and which is hard work. 

 S. stellatus, Curt. — Yery common at Loch Rannoch ; occurred also at Loch Ericht. 

 S. latipennis, Curt. — A single ^ at a moor stream at foot of Cross Craig. 



Micropterna sequax, McL. — A ^ bred from a case found in a dribbling stream 

 running down Camcreagh. The stones lying around were dotted with nymph skins 

 presumably of this species. M. lateralis, Steph. — Very common. 



EccUsopteryx guttulata, Pict. — Dall Burn and Loch Ericht. 



Apatania Wallengreni, McL. — -Abundant all along Loch Rannoch side, but we 

 must surely have been too late for the S , to wliich sex hardly 10 per cent, of the 

 specimens taken belonged. 



SERIC'OSTOMATID^. 



Sericostoma personatum, Spence. — Taken singly at Loch Ericht and elsewhere. 

 Brachycentrus submibilus, Curt. — Two specimens from River Gaur (this species 

 would be over). 



Lepidostoma Jiirtum, F. — Not uncommon. 

 Lasciocephala basalis, Kol. — A single J at Loch Ericht. 



LEPTOCERIDJE. 



Leptocerus nigronervosus, Retz. — In profusion along a calm reach of River Gaur. 

 The specimens taken here were paler in colour and larger than a few from the Loch 

 side, which were small and dark. 



Tricenodes bicolor, Curt. — Occurred near the locality mentioned for P. striata. 



HYDEOPSYCniD^. 



Sydropsycke pellucidula, Curt. — Two $ on River Gaur ; the species probably 

 over. IT. guttata, Pict. — Only one ^ from near the head of Loch Rannoch. H. 

 instabilis, Curt. — A <? taken near the Loch. 



Philopotamus montanus, Donovan. — Dall Burn and elsewhere, sparingly. 



Plectrocnemia conspersa. Curt., P. geniculata, McLach. ; Polycentropus Jlavo- 

 maculatus, Pict., P. multiguttatits, Curt. — All taken at moor streams by beating the 

 overhanging heather ; and all common, save P. geniculata, of wliich only a few 

 specimens were taken. 



Cyrnus trimaculatus, Curt. — Only one specimen preserved, but doubtless 

 common. 



EHTACOPHILID^. 



Rhyacophila dorsalis, Curt. — Common. 

 Agapetus fuscipes, Curt. — Only one or two taken. 

 Olossosoma vernale, Pict. — Occurred singly. 



HYDROPTILID^. 



Hydroptila femoralis, Eaton. — Not uncommon at Loch Ericht and Loch 

 Rannoch. 



Oxyethira costalis. Curt. — Common everywhere. 



NEUROPTERA-PLANIPENNIA. 



SIALID^. 



Sialis lutaria, Lin., and S.fuliginosa, Pict. — Occurred on the Dall Burn.
