120 Mr. G. T. Baker’s descriptions of some 
with greyish fringes. Head and palpi whitish, dusted beneath 
with blackish minute irrorations. Length, 243 mm. 
This Pleurota will follow Macrosella, from which it 
differs by its smaller size and its darker and greyer hue. 
It is also a rougher-looking insect, having the appearance 
of being thickly covered with coarse greyish scales. 
Six males and two females were taken at Sebdou, all 
of which are in my collection; they differ slightly enter se, 
some specimens being paler than others. I have (with 
his kind permission) dedicated this Plewrota to Mr. 
Stainton, who is so well known in connection with 
Micro-Lepidoptera. 
Pleurota Mauretanica, n. s. 
Alz antice ochraceo-fusce, margine interiore pallidiore, vittis 
duabus (costali et centrali) argenteo-albidis. Ale postice cinerex. 
Palpi, capite et thorace longiores. 
The anterior wings are of a warm brown colour, with a slight 
chestnut tinge. The costal stripe, extending almost to the apex, 
is silvery white; the central stripe, also silvery white, is of 
moderate width, and extends right up to the hind margin ; it is of 
uniform width for about two-thirds of its length, when it narrows 
suddenly for the remaining third, but does not produce a tooth. 
Fringes greyish white. The posterior wings are dusky grey, with 
paler fringes. Head, palpi, and thorax whitish, dusted with grey. 
The palpi are thickly dusted beneath with dark grey, and are 
slightly longer than the head and thorax. Length, $ 24, 2? 22mm. 
One pair were taken at Sebdou, which are in my collec- 
tion. The species should be placed between Schlegeriella 
and Algeriella; from the former it may be recognised 
by its larger size, its broader and more silvery costal and 
central stripes, and by its richer and glossier colour. 
From Algeriella it may be distinguished by its darker 
colour, by its central stripe being narrower, less silvery, 
and not toothed on the fold; and in the female the 
costa of the anterior wings is decidedly straighter and 
the apex less acuminate than in that species. 
Pleurota Oranella, n.s.

prope ad apicem inferiore ad angulum analem currente, ciliis 
margaritaceis. Alw postice subhyaline cinerew; cillis coloris
