northern species of Lai'entia — ccesiata and salicata — abound on 

 the hills ; but flavicindata is scarcer, and more local, though 

 found in the woods as low as 500 or 600 feet. Einmelesia ericdata 

 may fairly be called common, and goes up as high as 2200 feet; 

 while a single specimen (rather peculiar in its markings) of E. 

 blandiata^ which occurs here and there in the glen, was taken 

 by Mr Herd at an altitude of 2400 feet. I think, however, that 

 it does not usually live so high up. Of that interesting genus 

 Eiipithecia, several noteworthy species occur. E. constridata 

 has been taken sparingly at rest on rocks, with the commoner 

 E. pidchellata. The form of E. satyrata known as callunata is 

 of course common. (Mr Harpur Crewe has, I believe, proved 

 that callunata is only a northern form oi satyj-ata.) In the woods 

 near Blair, the larva oi E. iogata has been found in spruce cones. 

 Coremia munitata is very common in the upper part of the glen, 

 where also a curious variety of C. ferrugata was taken in July last 

 by Sir T. Moncreiffe (2 specimens) and Mr Herd (i). This 

 insect puzzled us immensely ; and we at last concluded that it 

 was a new species. Dr Staudinger of Dresden tells us, however, 

 that it is clearly only a form oi ferrugata, and that he has similar 

 forms from the mountains of N. Italy and Sweden. It is certainly 

 very different in appearance both from the usual Scottish form, 

 and from the very different English form of this variable insect. 

 Eidonia carbonaria ought to occur in several places, but as yet 

 we have only found it in one, and, as usual, amongst Ardo- 

 staphylos uva-ursi. Psodos coracina inhabits most of the higher 

 tops, generally where Azalea procumbens grows ; and in the glen 

 Dasydia ohfuscata has been found in several places. Melanippe 

 galiata, though not a rare species in Britain, yet is one whose 

 occurrence in Glen Tilt is rather curious. It is not found, I 

 think, in Lowland Perthshire, and in fact is in Britain commoner 

 on the sea-coast than elsewhere, though not a maritime species. 

 Out of Britain, its distribution is in Central and Southern Europe. 

 In Glen Tilt I have seen it at 1400 feet at rest on the same stone 

 with the northern Larentia ccesiata and Emmelesia ericdata. It 

 also occurs in Rannoch. 



In the woods the handsome Geometra papilionaria is sometimes 

 met with, and wherever larch has been planted Boarmia crepus- 

 cularia may be found. On the boles of the birches in spring 

 Lobophora lobulata may be frequently seen at rest; and on white 

 poplar Z. hexapterata, but more rarely.
