Sp. 3. atromargana. Alis anticis cinereis fusco nebulosis, maculCi albida communi 

 strigisque ohsoletis subargenteis, posiicis fiiscis basi dilutioribu.s. (Exp. Alar. 

 5—6h lin.) 



To. atromargana. Haworth. — Ps. atromargana. Steph. Catal. ii. 175. 

 No. 6918. 



Anterior wings ashy, coarsely clouded with deep fuscous, with a large trape- 

 ziform whitish spot in the middle of the inner margin, in which is an ashy 

 streak ; behind this on the hinder margin are two very short interrupted 

 silvery streaks : the costa is prettily streaked with white and black : posterior 

 wings fuscous, with the base pale and the apex very dark. 



The colours are occasionally much brighter, and therefore by the contrast give 

 the insect a different aspect. 



Not very common ; foimd in Oak woods in June. I have taken 

 it at Darenth, Birch, and Coombe woods, and also at Hertford and 

 Ripley. 



Sp. 4. Strobilella. Alis anticis pallide fuscis, subnebulosis, postice argenteo 

 strigosis, punctoque atro, fascia media abbreviata albida, costa lineolis argentcis. 

 (Exp. Alar. 4 — 5^ lin.) 



Ph. Ti. Strobilella. Xm«t'.— Ps. Strobilella. Steph. Catal. ii. 175. No. 6919. 



Anterior wings pale brown, with irregular silvery streaks, consisting of an 

 obscure one at the base, a more conspicuous angulated one in the middle, 

 and a third interrupted one behind : in the middle of the inner margin is a 

 short divided whitish blotch ; and in the middle of the posterior streak a 

 minute black dot, and occasionally one or two minute ones on the anal 

 angle of the posterior margin : on the costa are several minute short silvery 

 lines : posterior wings dusky. 

 Found towards the end of May in fir woods ; not very uncommon 



near Hertford. 



B. Anterior wings broad, of plain brown hues, generally with a lunate pale or 



yellow dorsal blotch, and oblique pale costal streaks: — Heusimene,

media communi argented, posticis piceis. (Exp. Alar. 4§ lin.)

 Anterior wings cinereous, with angulated transverse silvery and yellow 

 streaks, the costa towards the apex with very short white lines : towards 

 the anal angle are two or three very minute black dots ; and on the middle 

 of the inner margin is a lunate silvery blotch : posterior wings pitchy. 

 Scarce ; found in the beginning of June in woods within the me- 

 tropolitan district and in Norfolk.
