new species of Lepidoptera from Algeria. 119 
posteriore late griseo-fusca, sed fimbria angusta pallida punctis 
nigrescentibus ; ciliis cinereis. 
The anterior wings are of a greyish buff; the first transverse 
line near the base fairly distinct and of a greyish brown colour ; 
the second transverse line immediately behind the dark central 
spot is almost obliterated. The two posterior transverse lines, 
_ placed close together, are moderately distinct, and of a greyish 
brown hue. The hind margin is bordered rather broadly with 
greyish brown, and is finely and darkly dotted. The posterior 
wings are of the same colour as the anterior wings; the middle 
transverse line is very distinct from the dark central spot to the 
inner margin, but is scarcely perceptible from the spot to the upper 
margin; the two posterior wavy transverse lines form a con- 
tinuation of the similar markings in the fore wings. The posterior 
margin is broadly bordered with greyish brown, but is edged at 
the extreme border very narrowly with paler grey; this posterior 
margin is also darkly and finely dotted. Fringes same hue as the 
wings. Body and thorax slightly darker than the wings. Length, 
16 mm. 
One male specimen of this obscure little Acidalia was 
taken at Sebdou, and is in my collection. 
Pleurota Staintoniella, n. s. 
Als antics cinereo-fusce, vittis duabus (costali et centrali) 
argenteo-albidis, apice subacuminato g', acuminato 2. Alex pos- 
tice fusco-cinerex, ciliis pallidioribus. Palpi capite et thorace 
longiores, cinereo-albidi irrorati punctis parvis cinereo-fuscis. 
g. Anterior wings greyish brown, occasionally inclining to 
tawny, with the costal and central stripes white, slightly silvery, 
the former extending nearly to the apex, the latter up to the hind 
margin just below the apex; both stripes are rather narrow, the 
central one attenuating as it approaches the posterior margin. 
The fringes are of a greyer hue than the wings, which latter are 
very slightly acuminate. The hind wings are dark sooty grey, 
with slightly paler fringes. Head, palpi, and thorax grey; the 
palpi are thickly irrorated with dark fuscous, and are rather longer 
than the head and thorax, the end joint being about the length 
of the head. Length, 22 to 24 mm. 
9. Anterior wings grey or ochreous grey, thickly irrorated 
with darker scales, with the costal and central stripe more silvery 
and broader, the latter extending right through the fringes, which 
are whitish, and the apex is acuminate. The hind wings are paler,
