AUGUST BUTTEKFLIES IN THE LANNION DISTRICT: 

 COTES DU NORD, BRITTANY. 



By John E. H. Blackie. 



Brittany is once more becoming a popular province in which 

 to spend an August holiday, and for this reason I think a short 

 account of the butterflies to be found there during this month 

 may be of interest to readers of the 'Entomologist.' Mr. 

 Rowland-Brown tells me that the greater part of Brittany has 

 been explored by M. Charles Oberthur and his collectors, but 

 that his work was confined chiefly to the departments of Morbihon, 

 Finistere and Ille-et-Vilaine. Cotes-du-Nord is therefore a rather 

 unworked country. I do not pretend to have made a systematic 

 search of the department, but I hope that my notes may serve as 

 a guide as to what one may expect in this part of the province. 



My headquarters were Trestrignel in the commune of Perros- 

 Guirec, a small village on the coast, about seven miles north of 

 Lannion. From here my observations extended to Tonquedec 

 and Kerfons, the site of an ancient ruined chateau, six miles 

 south of Lannion ; to Ploumannach and Tregastel, three and a 

 half miles west of Trestrignel ; to Louanec, two miles east of 

 Perros-Guirec ; and to Treguier — a cathedral city — twelve miles 

 east of Trestrignel. 



The Lepidoptera were interesting, but not anything out of 

 the way, and this was probably due to the wind-swept and 

 woodless type of country on the coast and the lateness of the 

 season. Inland, towards Lannion, there were large chestnut 

 woods where D. pcvphia was fairly common, but all along the 

 coast were heaths and bracken, less prolific in butterflies than 

 might be expected, although L. quercus careered up and down 

 them in large numbers. C. quadripimctaria was fairly common, 

 both the typical form and ab. lutescens. My chief object was the 

 collecting of butterflies, but I also took or noticed the following 

 moths: M. stellatannn, A. secalis, P. gamma, A. viridaria, C. 

 immanata and Z. tyirolii. 



Adopoea fiava. — Common at La Clarte (near Trestrignel), but 

 only occasionally at Trestrignel. Rather pale forms. 



Thymelicus acUeon. — Common during the earlier part of 

 August at Trestrignel. Fond of sitting on thistle-heads in 

 sheltered spots. 



Aricia inedon. — One at Trestrignel. Not common.
