Ph. Py. sulphuralis. Linne.—Don. x. pi. 339. f. 1.— Er. sulphurea. Steph. 

 Catal.pt. ii.p. 109. No. 6399. 



A beautiful species ; head and thorax sulphureous, with dusky-black spots : an- 

 terior wings suIphur-yeUoWj with three black spots on the costaj and two on the 

 disc ; at their base two stout black streaks arise running parallel with the inner 

 margin, and reaching about two-thirds the length of the wing, where they are 

 united by an undulated black striga arising on the costa, and in fine specimens 

 glossed with a silvery hue, and parallel with the latter is another waved striga, 

 of a deep black, and sometimes interrupted ; the hinder margin itself is irre- 

 gularly black; the cilia are black, with a whitish patch near the apex of the 

 wing, and a smaller one towards the anal angle; posterior wings dusky-black, 

 with a whitish fringe : body grey-brown, with yellowish belts. 



The discoidal black spots on the anterior wings are sometimes confluent with the 

 outer oblique striga ; and the oblique strigae are occasionally united by two 

 slender black lines a little beyond the middle. 



Caterpillar grass-green with a black dorsal line, and yellowish lateral streak, 

 with a few white spots above : it feeds on the convolvulus arvensis :— the imago 

 appears about the middle of July in clover-fields. 



A rare species : it has been occasionally captured in Battersea- 

 iields, flying about during the daytime amongst flowers ; it lias also 

 occurred near Margate, and in other parts of Kent. 



Sp. 2. uncana. Alls anticis fuscis, viargine anteriori albido, medio ramum re- 



curvum exserente. (Exp. alar. 11 — 12 lin.) 

 Ph. Ge. uncana. Linne.—Er. uncana. Steph. Catal. pt. ii. p. 109. A'b. 6400. 



Head and thorax reddish-grey : anterior wings fuscous, with the anterior margin 

 white, its inner edge silvery, the costa itself fuscescent ; in the middle of the 

 disc, united to the whitish margin, is an oblique stigmatiform patch, with its 

 centre slightly fuscous and margins snowy, the latter sometimes throwing off 

 a twig towards the posterior margin; behind this is an abbreviated white 

 streak nearly parallel with the posterior margin, and bearing a delicate fus- 

 cescent striga, and the margin itself is white, with a fine brownish line in- 

 teriorly : posterior wings fuscous ; all the cUia fuscescent, with a darker Une 

 near the base. 



Caterpillar green, with a paler lateral line; it feeds on Carices:— the imago ap- 

 pears towards the end of June. 



Considerably more abundant than the preceding species; occurring 

 in some plenty on the borders of Whittlesea-mere, and in marshy 

 places in Norfolk ; in the New Forest, Hants, and in Devonshire.
