for this year are—Linn of Baldernock, 6th June; Crookston, 
13th June; Inchmurrin, 19th June. The Crookston speci- 
men was a male, the other two were females. 
7. lutescens, F.—This large and handsome species seems to be 
very local. From the 24th June till the end of July it was 
exceedingly abundant on the marshy ground and in the woods 
on the north side of the Allander, at Clober. The only 
other locality where it was met with was Tarbert, Lochfyne, 
where a single specimen was secured on 25th August. 7’ 
lutescens seems to be much more infested by parasites than 
any other species. I caught a specimen at Clober, the thorax 
of which was completely covered with mites, and their scarlet 
colour gave it a very brilliant appearance in the sunlight. 
T. oleracea, Linn.—In other parts of the country this is a very 
abundant and destructive insect, but it certainly was by no 
means common with us this year in the perfect state. We 
obtained a few specimens at Crookston on the 13th June, and 
at Kirn on the 20th idem. It was also brought to me from 
Troon and Fintry about.the same time, but none was seen 
after the end of June. 
T. naludosa, Mg.—This isthe commonest species of the whole 
genus, and shares with 7’. oleracea the name of Crane-fly. It 
did not appear till the middle of July, but after that it 
simply swarmed, and is still on the wing. I need not specify 
any localities, for very little difficulty will be found in getting 
it even in Glasgow itself. It did not appear until some weeks 
after 7’. oleracea had disappeared, and this lends some colour 
to Mr. Verrall’s theory that the two are only seasonal forms 
of the one species. The only differences that can be detected 
are the short wings of the female 7’. paludosa, and the want of 
the white streak below the costa so conspicuous in 7’. oleracea. 
T. ochracea, Mg.—This species appears to be very local with us. 
It was very abundant on the Caddercuilt Road on the 26th 
June. Mr. Brand, a member of the Andersonian Naturalists’ 
Society, brought me a boxful from that locality. Kirn, 20th 
June; Milngavie, 27th June. 
Dictenidia bimaculata, Linn.—A female, in Bellahouston Park, 
13th June.
