LEl'IDOPTERA OF THE SCOTTISH HIGHLANDS. 131 



following notes may be of intere?t. My best thanks are clue to 

 Prof. J. J. F. X. King for his kind help in the identification of 

 a niiraber of the micros recorded below. 



My year's collecting began with an examination of the shoots of 

 Arctiistaphi/loK nva-ursi, which, interspersed with heather and whortle- 

 berry, cover large tracts of a moorland hill in this neighbourhood 

 (Swordale, Evanton). I was rewarded with quite a number of larvre, 

 mostly fullfed, of Com/.j; nenxniva/ia, each devouring the parenchyma 

 of a leaf, which latter, in consequence, was swollen out to a bladder-like 

 form. One could easily detect the presence of a larva by the withered 

 leaves on a growing shoot which had been formerly tenanted by a larva, 

 and were now connected with those more recently excavated by means 

 of silken threads passed through a small hole from one leaf to 

 another. The larvae still continued to feed for a little time, and the 

 first pupa I noticed — inside one of the bladder-like leaves — was on 

 April 29th, and the first imago emerged on June 23rd. 



In the end of March, a visit to some neighbouring cliffs edging a rush- 

 ing mountain burn and overgrown in parts with clumps of wet moss and 

 Sa.vifraiia a Glides produced seveviil lavwe oi Larentia jiavicinctata {rufi- 

 eincta), which, still very small, were easily shaken out of the saxifrage 

 plants. I noticed the larvje of this species again in the same ravine, 

 where they seemed fairly common, towards the end of April, whilst 

 searching for larvse of Brentlm enplimsijne on the steep grassy slopes, 

 where the leaves of Viola canina were just appearing above the withered 

 bracken fronds. In this quest I was also successful, securing one or 

 two larvae by turning over the withered leaves near freshly eaten violet 

 plants and in so doing accidentally dislodged an imago of Pachnobia 

 riihrirona. The imagines of Brentlm eiiphrosyne were particularly 

 abundant near Swordale this year (1909) and were to be seen flitting 

 about in numbers in their favourite localities in the few days of sun- 

 shine at the end of May and beginning of .June. The same weather 

 brought forth PJn/tometra viridarin (all ab. fmca, Tutt), frequenting 

 either the dry grassy slopes, where the bright little Pancalia latreilldla 

 abounded, or the sheltered heathy banks, the haunt of Anarta nii/rtilli 

 and the much more local Venilia maodaria. The latter I found here 

 quite commonly in its very few favoured spots, always on some sunny 

 slope in the neighbourhood of Tencrium scorodonia. 



A light trap, placed near here in a wood of birch and aspen, 

 attracted on the mild nights of April, such species as A^phalia 

 davicnrnis on the 9th, and Taeniocainpa popideti on the 23rd. Owing 

 to continued bad weather the trap was not lit very often during the 

 summer, and the only moth captured of any interest was Ptiifiina 

 tenchriisa on July 11th. A short time spent beating in a wood of 

 birch and sallow on the shores of Loch Maree on June 25th was 

 rewarded, in addition to many common larvji?, with imagines of 

 Adela cKpiclla, Litliocollctis idiiiifoliella and Hepialtis ht'ctus. The 

 latter was also taken a little later near Swordale. Other Lithocolletids 

 observed here this year were /.. fai/iiiella on ^lay 30th, and /.. (jiierci- 

 foUella on June 10th, and again on September 2nd. 



The small birch trees which clothe in parts the banks of the ravine 

 spoken of above, swarmed from the end till the middle of June with 

 Phloeodea tetraquetrana. The same locality produced on June 21st, 

 two specimens of Swaminerdamia hcroldclla, and one of Pentliina
