Metopoceras Jchallhlja, Oberth. — Constantine ; one specimen at light. 



Plusia gamma, L. — common in some parts of the desert at Biskra, and I also 

 saw the larvae on the flowers of one of the Composiice. 



CiicuUia umbratica, L. — one on a gas lamp at Constantine. 



Eupithecia tamarisciata, 'Erv.—Const&Tiitme and Philippeville, rather common 

 on lamps. 



Cidaria decolorata, Hb. — Philippeville ; one worn specimen. 



Larentia fltictuata, L. — common at Constantine on ^as lamps ; the specimens vary, 

 but are mostly larger than English, and at first sight very different looking, the 

 ground-colour being greyer and the markings little darker than the ground. 



Anthometra megearia, Oberth. — two specimens at Biskra. 



Acidalia virgularia, Hb. — Philippeville, Constantine, Bougie ; generally com- 

 mon. All the specimens are of the white southern variety, and I quite failed to 

 recognise their identity until I got home. A. emutaria, Hb. — one specimen near the 

 gorge at Kharata. 



Metrocampa honoraria, Schiff. — Bougie ; one specimen. 



Cornifrons ulceratalis, Ld. — Biskra ; one specimen at light. 



TiTANIO ZACHLOEA, n. sp. 



(? . 17 mm. Head and thorax black, strewn with whitish-ochreous scales and 

 hairs ; frontal prominence moderate, without accessory spines. Palpi mixed with 

 blackish and whitish ; maxillary moderate, dilated with loose hairs ; labial clothed 

 with very long rough projecting hairs beneath. Antennae whitish-ochreous, marked 

 with black, ciliations long (3), fasciculated. Abdomen black, densely strewn with 

 whitish-ochreous scales. Legs whitish-ochreous, anterior and middle pairs partially 

 suffused with grey, femora densely hairy beneath. Fore-wings elongate-triangular, 

 costa almost straight, hind-margin somewhat obliquely rounded ; pale brownish- 

 ochreous, mixed with whitish-ochreous and irrorated with black ; costal half suffused 

 with whitish-ochreous from base to middle ; lines blackish, ill-defined, first from 

 one-fourth of costa to two-fifths of inner margin, somewhat bent below middle, 

 second from four-fifths of costa to three-fourths of inner margin, slightly indented 

 beneath costa, thence to below middle gently curved outwards, anteriorly strongly 

 margined with whitish-ochreous ; a small transverse discal spot beyond middle in- 

 distinctly formed by black irroration ; a whitish-ochreous streak along hind-margin ; 

 a fine blackish hind-marginal line ; cilia whitish, with a grey median line becoming 

 black at apex, basal half finely barred with black, with a blackish spot at anal angle. 

 Hind-wings clear pale whitish-ochreous ; a dark grey discal dot at one-third ; a 

 curved, well-defined, strong blackish line at three-fourths, parallel to hind-margin, 

 obsolete on costa ; a few scattered black scales between this and hind-margin ; a 

 narrow black streak along hind-margin throughout ; cilia whitish, basal fourth 

 whitish-ochreous, mixed and obscurely barred with black. 



Biskra ; oue specimen, iu perfect condition. The species is 

 probably nearest to T.Jioralis, but very distinct from it structurally 

 by the very long hairs of palpi, and hairy femora, as well as in colour 

 and marking. The genus Titanio is to be understood as defined in my
