head and thorax united, oval, much narrower than the thorax at the 
shoulders, widest at the middle, with their apex moderately rounded, 
deeply asperate in close wavy rows; legs long, slender, bright yellow. 
I give the above short description of this very distinct and pretty 
species in order to assert my claim to priority. I have named it 
Edithia in honour of its captor, Mrs. Wollaston, who, with the assistance 
of Mr. Wollaston, made a numerous and very interesting collection of 
these insects, in the neighbourhood of Tonbridge, during the past 
summer. 
TRICHOPTERYX CANTIANA, 0. 8. 
Differs from VY. data in having its thorax much less dilated at the 
sides, and the antenne rather shorter, more robust, and entirely black, 
also in its deep black colour and very short pubescence. 
Several specimens of this insect. were taken by Mr. and Mrs. 
Wollaston at Tonbridge.

NOTES on tHE G@CONOMY or SOME BRITISH SPECIES or PTEROPHORIDE 
(ISODACTYLUS, TEUCRII, PLAGIODACTYLUS, anv LIENIGIANUS).

PTEROPHORUS (PLATYPTILUS) ISODACTYLUS. 
In the autumn of last year, I picked up a few specimens of Pterophorus 
isodactylus in a marsh by the river side, and therefore looked over the place 
early this summer for plants of some species of Senecio. 
The grass, however, was rank and growing rapidly, and Senecio hard to 
find, and it was not till June 21st that, extending my researches into an un- 
explored corner, I found an ugly, scrubby-looking species—Senecio aquaticus— 
growing in some plenty. My search for the larva was, however, cut quickly 
short by the appearance of a specimen of the moth already out, and then and 
afterwards I secured a good many, the females being so exceedingly sluggish, 
that I only took two specimens of that sex. I had, therefore, to wait for the 
second brood to make the acquaintance of the larva; but, according to the 
contrary nature of things in general, just as the moths must have laid their 
eggs, the marsh was mowed, and, although the farmer had distinctly promised 
to leave a patch of the plants for me, the whole of them were cut down. 
This was discouraging enough, as the eggs had not had time to hatch, and 
must have been nearly all destroyed, whereas, had the larvee been feeding, some 
of them would have been sure to find their way from the withering plants to 
portions which remained growing. 
But, not to be beaten without an effort, I went to work on August 10th, 
and after a long search found one larva mining a shoot of the ragwort, and 
sent it at once to Mr. Buckler. A fortnight later, I found several larvze and 
a few pupe, from which the moths began to emerge on August 20th.
