terminal spurs only. Abdomen not crested. Forewing with costa slightly arched, apex moderate, termen 
oblique, slightly curved, cell about one-half, DC incurved, often very deeply, SC! very short-stalked 
with SC?^ (or connate, or closely approximated), anastomosing with or running into C, SC? normal, 
anastomosing with or running into SC! (or C), R! stalked, M! short-stalked (or in uubigena connate); hind- 
wing with apex rounded, termen smooth, more or less rounded, tornus squared, cell short, DC? shortly 
inbent anteriorly, then slightly or moderately oblique, C anastomosing to near end of cell, SC? long- 
stalked, R? from scarcely or only quite moderately above middle of MC, M! short-stalked. 
LaRva. — Moderate, head small with two small points, retracted under prothorax, prothorax 
high, strongly bifid, body with lateral flange, no humps, anal flap ending in sharp point, spiracles rather 
prominent. On. PZillyrea (Hofmann. Raupen Grossschmett. Eur. p. 160, beryllaria). Milliére once found a 
larva on olive (Zcon. Vol. 3, p. 462.) 
Pura. — Green (not described), in slight cocoon among food-plant.

Characters. — Face smooth. Palpus in Q quite short, terminal joint small (cf unknown). 
Antenna in Q bipectinate. Hindtibia with terminal spurs only. Abdomen not crested. Forewing rather 
narrow, costa almost straight, termen rather strongly oblique, cell just over one-half, SC! from cell, 
running into C, SC? normal; hindwing rather narrow, termen smooth, rounded, angles not pronounced, 
cell rather long, DC nearly vertical, C anastomosing to near end of cell, SC? long-stalked, R? from about 
the middle of DC. 
Early stages unknown. 
We have drawn the above characters from notes made on a hurried examination of Warren's 
type. It is altogether anomalous, and cannot be placed in any existing genus. The aspect is Acidaliid,
