shade is usually composed. This insect appears to ascend to 

 the higher branches as speedily as possible after emerging 

 from the pupa. At least on one occasion I intercepted a fine 

 female running up the bole of a birch, the wings being still 

 moist and flaccid, and I have never observed one at rest on 

 the trunk. 



C. Jtac'icorm's.-— Not uncommon. The earliest record ot 

 this insect being taken at Moncreiffe is March 6, 1872, and I 

 mention the circumstance in order to encourage young collec- 

 tors in their separate districts. Being a beginner myself, as it 

 were, in those days, I was in quest of information, and asked 

 Dr. Buchanan White if he could assist me in my endeavours to 

 obtain specimens of the Lepidoptera of the district, by suggest- 

 ing somethins; to look for. He said C. fiavicoriiis ought to 

 occur here on the birches. I pointed to a spot where the 

 birches were always early, and said will you come and look 

 for it ? He acquiesced, and off we started. We had not 

 examined more than two or three trees, when I found a 

 specimen cHnging to the trunk at a foot from the ground, 

 about 3 p.m., since which time I have observed \\i2Xflavic0rnis 

 usually emerges here after mid-day, as I have examined trees 

 before that time without result, which have afforded newly 

 risen imagos later in the day. This is a more refined looking 

 insect here than in Rannoch, where it abounds. In the 

 Moncreiffe specimens the costal margin for two-thirds of its 

 length, the discoidal spots, and the lines, have a beautiful 

 yellow tint, which is entirely absent in the Rannoch specimens. 



Bryophila perla. — Common at the park wall, at an altitude 

 of about 50 feet. Dr. Buchanan White and I, when looking 

 for land-shells, found the larvae under loose fragments of a trap 

 rock at an altitude of 500 feet. Comes to light. 



Acronycta psi. — Common everywhere up to 200 feet. I have 

 not observed it above that altitude. Mr. Herd tells me that he 

 finds the larva of A, tridens feeding commonly along with that 

 of psi. I cannot say that I can distinguish the difference in 

 the imagos. 



A. ligustri. — Common at sugar in July. I have not observed 

 it over 300 feet. Our specimens are darker than those from 

 the south. 



Leiicania conigera. — Common at sugar and at ragwort blos- 

 som, and particularly attached to the blossom of woodsage 

 (Teiicrittm scorodonia).
