Capilli depressi. Ocelli nulli. Antenne setaceze, articulis oblongis via 
distinctis, 8 non nodulosis, pubescente-ciliatis. Haustellum mediocre, 
squamatum. Palpi labiales artieulo secundo infra seopiformi, pilis 
antice productis; articulo ultimo levi, aculeiformi, recurvo. Ale 
elongate ongius ciliate, anteriores, cilia circa apicem productum picta, 
posteriores trapeziformes ante apicem levissime retuss ; anteriores : 
vena apicalis furcata ante apicem exit, cellula secundaria nulla, ven 
medianze ramus primus a secundo valde distat ; subdorsalis fureata ; 
submediana non incrassata; posteriores: cellula costalis normalis ; 
vena subcostalis prope basim furcata ; mediana trifida. 
Head smooth. Ocelli none. Antenne setaceous, with the joints 
oblong, scarcely distinct ; in the 8 not knotty, with pubescent ciliations. 
Tongue of moderate length, clothed with scales. Labial palpi with the 
second joint beneath formed like a brush, with the hairs produced in 
front; the terminal joint smooth, pointed, recurved. Wings elongate, 
with rather long cilia ; the cilia of the anterior wings round the produced 
apex are adorned with markings; posterior wings trapezoidal, very 
slightly retuse before the apex. In the anterior wings the furcate api- 
cal yein runs into the costa before the apex, the secondary cell is not 
indicated, the first branch of the median vein is at a considerable distance 
Jrom the second; the subdorsal vein is fureate; the submedian is not 
thickened. In the posterior wings the costal cell is of the ordinary 
form; the subcostal vein is furcate from near the base ; the median vein 
is trifid. 
We have only two species in this genus, which may readily be 
distinguished as follows :— 
a, With no streaks from the costa before the apex. Species 1. 
aa. With several streaks from the costa before the apex. Species 2. 
(There are several other continental species in the latter section.) 
Very little is known of the habits of the perfect insects, and none 
of the larvae are known.

Head and face pale grey. Palpi pale grey; terminal joint at the 
apex fuscous. Antennae dark fuscous, Anterior wings brown, rather 
suffused with grey, especially along the inner margin, the costa to be- 
yond the middle narrowly white; on the fold before the middle is an 
oblong dark fuscous spot, and beyond the middle are two dark fuscous 
spots on the disc, beyond the lower of which some of the veins are in- 
as eee
