NOTES ON A MONTH'S COLLECTING IN NORMANDY.

(5) Lestes sponsa was fairly plentiful in certain localities.
Our first specimens were taken on July 10th, and our last on
August 21st.
(6) Sympetrum striolatum was not so common as usual; our
captures ranged from July 17th to September 24th.
(7) Libellula depressa.—Although this active species had been
on the wing for about six weeks, we were unable to obtain an
example until July 24th. Our specimen was a male, and the
yellow lateral spots on the dorsal surface were confined to seg-
ments three and four, instead of being extended to segments five
and six, as in the typical form.
(8) AEschna cyanea fell to our net on several occasions be-
tween August 13th and October 9th.
(9) AE. grandis we found to be scarcer than usual; we collected
only one specimen (August 28th).
We have again to report the apparent absence of Sympetrum
sanguineum, at one time tolerably abundant near Chingford.
This year AEschna mixta seems to have disappeared entirely from
our locality. Another species remarkable for its seeming total
absence was Anax imperator, a specimen or two of which may
usually be seen, in the proper season, hawking over a certain pond
in the neighbourhood of Loughtou.
