it. A’schna cyanea was unusually scarce, and the heavy rains in 
July brought Calopteryx virgo to a very premature finish. 
Amongst other Newroptera taken was the curious “snake- fly ”’ 
(Raphidia). A few Osmylus chrysops (one at ‘‘ sugar’’), and a 
single Nothochrysa capitata (from G. Gulliver). With Orthoptera 
I did little. The ‘“‘ wood-cricket,” Nemobius sylvestris, was 
plentiful by the side of rides in enclosures, together with Tetrix 
bipunctatus, and I turned up a few of the very fine bog ‘ grass- 
hopper,’ Mecostethus grossus, at Denny Bog, and Norley Wood. 
Good ‘‘ Longhorns” (Locustodea) were scarce. Locusta (Phas- 
gonura) viridissima was not seen. 
In a quiet little way it has been quite a Cicadetta montana 
year. Ramnore is the best-known place for this interesting 
insect, but it extends for several miles beyond that spot, as well 
as occurring in another locality. My first specimen was taken 
on June dth, and after the lapse of a week several more were 
found (one in a collector’s killing bottle !), and they continued to 
appear until the end of the month, empty nymph cases being fairly 
frequent. One hot morning they flew very wildly, but I obtained 
all I required from the ground, where, probably recently emerged, 
they attracted attention by a peculiar rustling sound, very 
similar to the noise made by the larger ‘‘ dragon-flies ’’ when 
resuming flight after a rest. Hor this reason Anaa imperator 
frequently deceived me into thinking that Cicadetta was about.

LEPIDOPTERA IN PERTHSHIRE, 1920. 
By F. G. Waittte. 
Karty in April I spent a week at Struan, where Nyssia 
lapponaria occurred sparingly over a wide area. From ova 
obtained I secured a healthy brood of larve, which did well on 
Myrica, and duly pupated. From Struan I ‘went to Forres, and 
in one of the numerous clearings in the Altyre Woods netted, 
April 17th, Evetria logea (duplana), Drnt. That interesting beetle 
Thanasimus formicarius was found on a pine trunk May 6th; 
Eupithecia albipunctata and full-grown larve of Ortholitha plum- 
baria on tops of Ulex on 7th; on 12th Mamestra glauca emerged 
(Rannoch larva). I left Forres for Rothiemurchus, and found, in 
plenty, the resinous nodules of Hvetria resinella. Hvetria logea, 
Drnt., also occurred on ground very similar to that on which I 
took the species near Forres. A few days after this a disastrous 
fire swept over this spot, and must have been very destructive of 
bird and insect life. Thera cognata larve and pupe of Argy- 
resthia arceuthina were found on juniper on May 17th; Stigmonota 
dorsana occurred on Lathyrus montana, var. tenuifolia, near the
