8. Dubrisana, Curtis. Alls anticis olivaceo-stramineis, atomis fas- 

 ciisque duabus indistinctis cinereis ; puncto nigro ante angulum 

 analem, altero costali nigris, punctulis subargenteis ; posticis maris 

 niveis marginibus fuscis ; fcemince cinereis apice saturatioribus. 

 rf Exp. al. 4-8 tin. 



Head pale olivaceous green. Face dark fuscous. Eyes black. 

 Palpi longer than the head, fuscous above and at the sides, whitish 

 beneath. Antennae blackish. Thorax umber, mixed with pale greenish 

 scales. Patagia : at the base same colour as the thorax ; the tips 

 whitish. Anterior wings dull, very pale primrose, mixed with 

 dusky or umber freckles, with an irregular silvery-lustred streak 

 before the middle, another beyond, and two others straighter and 

 more denned towards the apex, besides numerous similar spots 

 disposed over the disk. The costa is maculated throughout, and 

 towards the apex are two (the innermost largest and darkest) patches 

 of umber scales, and a still larger, but more suffused one, on the 

 dorsal margin, near the anal angle. Apical scales and cilia yellowish 

 white. Posterior wings pearly white, with the upper edge speckled, 

 and the apical portion narrowly bordered with fuscous. Marginal scales 

 and cilia white. Abdomen : at the base dull umber, whitish towards 

 the apex ; the apex very pale drab, or dirty white. $ Exp. al. 5-8 lin. 

 Anterior wings deeper coloured, and the freckling more distinct than 

 in the tf . Posterior wings pale fuscous. Marginal scales fuscous, 

 with whitish bases. Cilia greyish at the base, the tips whitish. 



Mostly a coast species, and there somewhat common; very 

 variable, both in size and colour. The ground-colour ranges 

 from white to pale ochreous, and the freckling from grey to 

 nearly black. It is very closely allied to A. maritimana; but the 

 latter insect is not so variable in sise, is larger, more coarsely and 

 thickly freckled, and the posterior wings in both sexes broadly 

 mottled round the margins. 



The imago appears in July and August, and occurs at Dover, 

 Deal, Margate, and other places on the coast. It has also been 

 captured on the Old Tram Road near Croydon, and in Worces- 

 tershire.
