pale costal margin, and sometimes emitting a twig towards the posterior margin ; ae oblique plain mute stripe 
runs nearly parallel with the apical margin, but does not extend to the costa, bearing a es sal ge brown

feeds on Carices; and the moth is taken in June, August, and September, in the marshes and fens of Hunting- 
donshire, Norfolk, Hampshire, and Devonshire, where it 1s not uncommon.

This species measures about * of an inch in the expanse of the fore wings, which are of an olive-green colour, 
with a small white costal spot at the base, two white fascia, one crossing the wing obliquely before the middle, 
and the second extending from the middle of the costa to the anal angle, and elbowed inwardly in the middle ; 
on the extremity of the costa is a small pale oblique lineola, and the apical margin is white ; hind wings whitish- 
gray, irrorated with olive scales. The caterpillar is green, with a white line on each side. The perfect insect 
appears about the beginning of July. Originally described in 1775,* by Fabricius, in the Syst. Entomol. p, 645, 
as a native of this country ; but Mr. Swainson alone possessed a specimen, until about 1825, when Mr. Haworth 
captured a considerable number at the end of June, amongst reeds and rushes in a boggy situation in Norfolk. 
AGROPHILA Guétnts, (BotspuvaL, Pars.) 
The antenne are of moderate length and setaceous in both sexes; the palpi rather short, compressed, with the 
terminal joint but slightly distinct, and conical ; the abdomen not tufted ; the wings rather oblong ; the spiral 
tongue long ; the caterpillars with only 12 feet, rather thickened in front ; the head small ; the chrysalides are 
inclosed in cocoons of earth and silk buried at a little depth under ground ; the habits of the typical species both 
in the larva and perfect state, as well as the structure of the latter, render its separation necessary from the other 
Agrophilz of Boisduval, which M. Guénée has formed into the genus Hydrelia adopted above. There is a second 
species from the East of Europe entering into the same genus as our British species, A. sulphuralis.

Pyralis trabealis, Villiers. 
This pretty species is rather less than ] inch in the expanse of the fore wings, which are sulphur-coloured, with 
9 black spots and two thick bars of white, of which three spots are upon the costa, two on the disc, preceding the 
bar, which runs from the base parallel with the hind margin, which is also black, extending nearly to the anal 
angle, when it is bent into an oblique bar, which runs nearly to the apex of the costa ; the apical margin has four 
black spots ; these are sometimes confluent, forming an irregular subapical bar ; the strige and the other spots are 
also sometimes more or less confluent together ; the oblique part of the black bar is silvery in fine specimens. 
The cilia are black and white ; the hind wings brown. The caterpillar is grass green, spotted with white, and 
with a dark dorsal line and yellow lateral streaks. It feeds on the small convolvulus growing in dry places, 



* The name given to this species by Fabricius must therefore prevail, from its long priority over that of Borkhausen.
