Many familiar forms were seen, some in great abundance, others 

 noticeably scarcer than on the previous occasion. jSSschna ccerulea, 

 Strom, belonged to the former category, Erehia epiphron to the latter. 

 These two outstanding types of our northern fauna received early 

 attention. Ascending the hill just on the other side of the river, 

 E. epipliron was found in fair numbers, and going towards the summit 

 (about 3000 feet) there were seen in greater or less abundance, 

 Sericoris irriguana, Scopula aJpinaJis, Scoparia alpina and Cramhus 

 furcatellus, the last being the least common. On no other occasion 

 were these Alpine species seen flying so freely. In striking contrast 

 was a day spent on Ben Lawers ; the wind was strong and cold, and, 

 although there were some glimpses of sunshine, not a single insect 

 was taken that day. It was not, however, lost, as nearly all the more 

 intesting Alpine flowering plants of that famous mountain were seen 



The only butterfly seen on this visit, and not mentioned in my 

 former notes, was Argynnis Aglaia, it was not common. Nudaria 

 mundana was found on old walls, and came frequently 'to lighted 

 windows. Hadcna pisi and a few" commoner and usually much worn 

 Nocfiics were the sole results of sugaring. The Plusice included iota 

 (much scarcer than puJchrina^ and Jestucce. Phibalapteryx viffatawas 

 the only additional Geometer taken of any consequence. Larvse were 

 conspicuously absent ; a brood of Pggcera hucephala, one or two 

 tiny larvae of the commoner Notodontidce and " hook-tips," being all 

 that were observed. In Neuroptera and Trichoptera more was done, 

 although the new records are not numerous ; one, however, being a 

 species of Oxijethira new to the British Isles. 



A striking feature was the absence of Chrgsopce. I was despairing 

 altogether of taking any example of the genus, and captured but one 

 in Glen Lochay near the end of the month, and another on Loch Tay 

 side on the very last day of our stay ; both appear to be C. alha. 



With regard to Trichoptera, a single small Micropterna lateralis was 

 taken at a considerable elevation when we were after E. epiphron. 

 Crunoecia irrorata was frequent at one spring. Leptocerus fulvus was 

 seen flying at a quiet part of a stream which issued from a mountain 

 lake. L. commiitntns was common on some parts of the river Lochay. 

 Bercea mauriis was common at several springs and moist places. In a 

 densely shaded part of one of the burns Polgcentropus Kingi and 

 Wormaldia mediana were found rarely. Five species of Hydroptilidce 

 were taken; IIydroptilaforcipata,^\i\Qh. was common; H.Maclachlani, 

 a single specimen at the locality of L. fuhms ; Oxijetliira costalis 

 common at Loch Tay ; O. faJcata, not uncommon at springs ; and,
