282 THE ENTOMOLOGIST. 



which to increase and multiply and devour the earth, is a 

 question worth discussing, and that some observers think might 

 be answered in the affirmative. So far as my humble opinion is 

 worth anything, I incline to the belief that the respective out- 

 breaks of the voles and the "hill-grubs" have no connection 

 other than in some little-understood climatic conditions.

PS. — On August 23rd I happened to be going across the farm 

 of Townhead, in Closeburn parish, Dumfriesshire, with some 

 friends, who, like myself, were at the time occupied in some 

 archaeological researches. I had been on the moor perhaps half 

 an hour or so, without any particular thought of Entomology, 

 when all at once, about 10.10 a.m., the antler moths appeared 

 in myriads. Thousands upon thousands of them were Hying in 

 all directions, most of them just amongst and over the flowering 

 heads of the spret {Junciis articulatus) ; but many were flying 

 higher in the a'r, and some mounted up out of sight. It was a 

 wonderful scene, and one that I would not have cared to miss. 

 The effect was altogether different to that presented by the 

 evening flight I saw near Loch Dungeon, described above. On 

 that occasion the range of vision was circumscribed to a circle of 

 a few yards by the gathering gloom of a dull autumn night, and 

 the moths might not have been noticed at all by those un- 

 accustomed to observation. But the sight of such vast numbers 

 of moths in broad sunlight was something entirely novel, and so 

 unexpected that I could not help gazing on it in wonder and 

 amazement. The thickest of the flight was over places where 

 the spret grew almost to the exclusion of everything else. About 

 12 o'clock the moths became much fewer, but during the whole 

 afternoon there were more or less always to be seen flying 

 about. Near 7 o'clock in the evening, when I left the hillside, 

 they were again becoming more plentiful. A somewhat remark- 

 able thing is that the "hill-grubs" were not noticed to a de- 

 structive extent on this farm.

THE NOETH AMEEICAN NOCTUID^ OF THE GENUS 



INGURA. 

 By A. G. Butler, Ph.D. 



Having recently had occasion to examine the species of 

 Ingura, and wishing to see whether Prof. Smith had included in 

 his synonymy an insect of that genus described by Walker under 

 the genus Suhrita, I was convinced that this author could not 

 have examined the drawers of our arranged collection containing 

 Ingnra ; inasmuch as, not only his synonymy, but his remarks
