EANNOCH IN JUNE. 229 



Vaccinium. From June 15th to 20th I worked chiefly in a 

 plantation of young Scotch fir, paying occasional visits to the 

 hills about 500 feet above it. Among the firs I met with Coccyx 

 cosmophorana, not uncommonly flying throughout the clay. I also 

 took on the wing in the afternoon sunshine a fine series of 

 Mixodia rubiginosana, Retinia pinivorana, and five R. dupland 

 (northern form of tur'wnana ?) ; also one Stigmonota coniferana. 

 In the swampy places between the fir trees Penthina dimidiana 

 and Phoxopteryx uncana were not uncommon, and Clepsis 

 rusticana occurred occasionally. Eupcecilia ciliella was in great 

 abundance in certain localities. On the hills, flying in the after- 

 noon sunshine among Arctostaphylos uva-ursi, I took a fine series 

 of Euchromia arbutana, E. myglndana, and Coccyx nemorivagana. 

 The last-named species occurred equally among heather, and I 

 should not be surprised to find this to be also its food-plant. 

 Among heather Mixodia schulziana and Phoxopteryx unguicana 

 were both common. Penthina prcelong ana, an abundant Rannoch 

 species, still lingered a little way up the hill-sides among birch. 

 Phlceodes tetraquetrana also occurred among birch, and Grapholitha 

 campoliliana among sallow. The last visit I paid to the Black 

 Wood was on June 24th, and on this occasion I took flying round 

 the branches of the fir trees a series of Coccyx coniferana ; also 

 one C. cosmophorana, the only specimen I noticed in the Black 

 Wood. Among Vaccinium, Mixodia palustrana, Coccyx usto- 

 maculana, Sericoris lacunana, S. irriguana, and S. daleana were 

 all more or less common. Irriguana is now, I believe, considered 

 only a small form of daleana, and it has been suggested to me by 

 a good authority that daleana is also only another form of 

 lacunana, an opinion I am inclined to share.* 



On June 25th, at about 2500 feet, I took a few Penthina stain- 

 toniana among its supposed food-plant, Vaccinium my rtillus ; and 

 on the same ground a few Amphysa gerningana. A little higher up 



* Is our correspondent quite sure that he captured the true Sericoris irriguana 

 in the Black Wood of Rannoch ? There is a form of S. daleana which occurs in the 

 Black Wood closely resembling S. irriguana. The latter in my experience is a truly 

 mountain species, never being found under 1500 ft., and more frequently at 3000 ft., 

 having quite different habits and time for flight. S. daleana flies in the afternoon, 

 after the manner of many other Tortrices ; while S. irriguana flies high, say, six or 

 eight feet above the ground, just before and after sunrise, and not freely in the 

 afternoon. Will Mr. Nicholas Cooke give us his opinion? I have taken »S'. lacunana 

 in the meadows below the graveyard at Camachgouran, and within a few hundred 

 yards of S. daleana, which is apparently a bilberry-feeder. — J. T. C.
