744 Rev. C. R. N. Burrows on the 
been taken, so far as I have been able to learn, its haunts 
are by running water irrespective of elevation, or of the 
neighbourhood of the sea. 
Mr. J. G. Le Marchant, who found it in plenty near 
Aberfeldy, N.B., writes me thus: “There is a strip of 
marshy, boggy g sround some two or three hundred yards 
wide, along the “side of the river, and some three or > Rotts 
miles long. It is covered with coarse grasses, rushes, and 
a good many flowers, notably “scabious.” There are also 
knapweed, hawkweed, and other flowers. It is along this 
strip that I have taken all the insects I send to you; there 
do not seem to be any on the slopes of the hills even close 
by. On the “ Knowie,” surrounded by rushes, they are 
very numerous when the sun is shining, sitting always on 
the scabious blossoms, sometimes three or four on a plant.” 
Mr. Buxton * at Liddelbank, N.B., and Mr. Sweeting on 
Loch Foyle, also noticed the predilection of this insect 
for the scabious, which may indeed prove to be its food 
plant. 
With crinanensis I have received a few nictitans and 
lucens, but I believe where it occurs this insect is found 
almost always alone. 
The localities which I have recorded for this species are 
Inveran (Sutherlandshire), Maddison collection ; Bellanoch, 
Crinan Canal, Messrs. Bacot and Simes; Aberfeldy, Le 
Marchant; Liddelbank, Messrs. Buxton; near Loch Foyle, 
BOR: Sweeting ; near Enniskillen, in Co. Monaghan, and 
Bolton, Lancs., J. E. R. Allen. 
All these insects appear in Britain at the end of August 
and beginning of September. 
Mr. Pierce and I had perforce, in the first instance, to 
differentiate our insects by locality. No difficulty arose 
as to finding the proper females of the species affecting 
my garden. Having separated the males of /wcens from 
nietitans, we recognised the female of this insect by her 
difference from the other insect. Proceeding, we found 
the female of crinanensis by her difference from that of 
lucens and nictitans. We may, I feel, claim that our con- 
clusions are fairly likely to be correct, though we admit 
that further examination, while it cannot well lessen the 
number of the species now under consideration, may 
possibly increase it. 
* Mr. Buxton writes me that it was more often ou thistle blossom.
