LEPIDOPTERA OF ASSYNT DISTRICT OF SUTHERLANDSHIRE. 77 



fuscous transverse strigae was common on the rocks on Soyea ; we 

 •could not find it on the mainland, although thrift was a common 

 plant along the seashore. 



S. cespitana. — A fine bright ochreous form of this species was 

 abundant on Soyea, and so far as our observations went it was 

 peculiar to it, for we could not find it on the mainland. 



S. lacunana* — A very small form. 



Mixodia schidziana*— Occurring sparingly at all levels that I 

 visited, i. e. up to 2000 ft. 



Euchromia arbutella. — Not uncommon amongst its food-plant 

 Arctostaphylos uva ursi. — At Lochinver. 



Orthotaenia ericetana* — Common at dusk flying in meadows. 



Cnephasia m'usculana* — Common, extremely bright forms. 



C. penziana. — This much -wanted and beautiful species 

 produced a mild sensation. On July 16th Mr. Whittle reported 

 that he had disturbed on a rock, but missed, a very handsome 

 moth, which from the momentary glance he had of it appeared 

 to be a "Nola," but if it was a species of that group then it was 

 new to Britain ! The next day I, too, disturbed a moth from a 

 rock, fortunately capturing it. Obviously it was C. penziana, and 

 on showing it to my friend he at once pronounced it to be his 

 lost prize. On the same evening I took another example, also from 

 a rock, but although we both searched rocks and walls for hours 

 each day for over a week, until after my departure further ex- 

 amples were not met with. Mr. Whittle, however, after that date 

 discovered one on the garden wall of the house in which we stayed. 



Bactra lanceolana* — Very abundant in all swamps up to 

 1500 ft. : the high-level forms were extremely small. 



Ancylis unguicella* — A few examples only. 



A. biarcuana* — Not uncommon amongst sallow. 



A. myrtillana. — One example at Inchnadamph. 



A. lundana. — Lochinver; not common. 



Grapholitha ramella— Eeported by Mr. Whittle from 

 Lochinver. 



G. subocellana.* — Abundant. 



G. penkleriana— Eeported by Mr. Whittle from Lochinver. 



G. tetraquetrana* — Abundant. 



Steganoptycha augustana — Extremely brightly marked speci- 

 mens were bred commonly in July from larvae obtained in sallow 

 shoots from Soyea ; one or two examples were taken on the 

 mainland. 



Paedisca semifuscana* — Larvae common on Myrica gale in 

 -July ; the examples bred were grey and brown forms only. 



P. solandriana.— Reported by Mr. Whittle from Lochinver. 



Halonota similana. — Lochinver, bred from birch. 



H. pflugiana. — Lochinver, fine large examples. 



H. trigeminana. — Lochinver. 



Semasia rufillana. — Lochinver.
