DIPTERA NEMATOCERA FROM ARRAN AND LOCH ETIVE 125 
Psilohelea (Lsohelea) nitidula, sp. n.—Closely allied to P. (Z.) 
soctabtlis, Goet., differing as follows :—Mesonotum brightly shining. 
eyes almost or quite bare; costal veins light brown; male 
hypopygium: side pieces more swollen than in soczadzi's, the base 
swelling out towards the base of the abdomen from the point of 
attachment; claspers stouter, more evenly tapering and niore 
sharply pointed; parameres stouter, blunter and with an upward 
instead of an outward curve at the tip; mesosome shorter, doubly 
emarginate at the tip. Type, male, in the British Museum, from 
Machrie, Arran; also eight other specimens of both sexes. 
Psilohelea (Lsohelea) perpusilla, sp. n.—Differs from P. nitidula 
as follows :—Size smaller (wing-length o.8 mm.); veins bordering 
the radial cells dark brown; side pieces of male hypopygium 
less swollen; apical part of ninth tergite broader; parameres shorter 
and less stout, curved downward at the tip; mesosome rounded 
at the tip, not emarginate. Type, male, in the British Museum, 
from Brodick, Arran; also six females. 
Quail in Midlothian.—It may be of interest to record the 
presence of the Quail in Midlothian, On zoth June the character- 
istic note, ‘‘wheet-wheet-wheet,” was heard in a grass field at 
Inveresk. It may be recalied that a similar visit was noted last 
year in the same district.—M. R. Tomuinson, Inveresk. 
Turtle Dove in Kirkcudbrightshire.—A female Turtle 
Dove was shot near Carsethorn, Kirkcudbrightshire, on 14th May 
1921.—HuGH S. GLADSTONE. 
Decrease of Ring-ouzel.— When writing my JSirds of 
Dumfriesshire in 1910, I wrote :—‘‘ Dumfriesshire may certainly be 
considered as one of the headquarters in Great Britain of the 
Ring-ouzel. Abundant as it is in the mountainous parts of Lake- 
land and the neighbouring counties, it can scarcely be more 
numerous ‘than it is with us in spring, when every crag and ravine 
at a suitable elevation may be confidently expected to be tenanted 
by a pair of breeding birds.” 
I regret to say that, of late years, this species has annually 
become more and more scarce locally, and I am entirely at a loss 
for any explanation of this. It would be, I think, of interest to 
know if a similar decrease has been noticed elsewhere than in 
Dumfriesshire, and any suggestions for the reason of this decrease 
would surely be welcoome.—Hucu S. GLADSTONE. 
Nesting of Fulmar Petrel on Forfarshire Coast.— As 
previously reported by Miss Baxter and Miss Rintoul the Fulmar
