irregular submarginal band inside the outer margin, and edged 
outside with a light colour. The outer margin, just inside the 
fringe, is usually edged with a blackish line—the marginal line. 
In the central part of the median belt there is usually in the cell 
a dark dot or streak, called the cellular, discocellular, or discal 
dot or streak. These markings refer mainly to the forewings. 
The following descriptions are in general quoted in the 
author’s words, but in several cases where the original description 
was vague or scanty the description has been rewritten or sup- 
plemented. I hope ina future number to extend the paper to 
the other genera of Larentiide, and also to give the remaining 
species belonging to the foregoing genera. 
Laventia semisignata, Walk.—Cinereous, minutely black speckled. 
Antenne of the male pectinated. FForewings with several denti- 
culated blackish lines, some of which are most conspicuous on 
the veins, where they form black points ; middle space without 
lines, containing the black transverse elongate discal point ; dn- 
terior, exterior, and submarginal lines formed by whitish points 
on the veins ; marginal lunules black ; costa convex ; exterior 
border hardly convex. Hindwings paler, with indistinct lines. 
Body 4 lines ; wings 12 lines. 
Lay. punctilineata seems to differ mainly in colour from L. 
semisignata. 
Laventia ?. megasptlata, Walk.—Cinereous brown. _Palpi stout, 
pilose, rostriform, extending much beyond the head, and about 
as long as its breadth. Antennz of male moderately pectinated. 
Forewings with numerous indistinct blackish denticulated lines ; 
interior and exterior lines whitish, accompanied by black points, 
having between them a large pale cinereous subcostal blackish 
bordered patch, which contains a black point; a black, oblique, 
bent, diffuse apical streak, which passes across the cinerous zig- 
zag submarginal line; marginal points black, elongated ; tips 
subfalcate, the exterior border being excavated in front. Hind- 
wings dull ochraceous, with indistinct brown lines. Body 4% 
lines ; wings 13 lines. 
This is a very variable species, and I think that Lav. nehata, 
falcata, and rufescens, are rather varieties of it than distinct species. 
Laventia ? nehata, Feld.—According to Mr. Butler this is allied 
to Lar. megaspilata, but is smaller; the primaries much darker 
and more uniform in colouring, the secondaries ochraceous. 
Laventia ? falcata, Butl—Allied to L. punctilineata (which it 
much resembles in colour and markings), but larger, and with 
distinctly falcate primaries ; primaries reddish-brown, with the 
base and a broad central belt dark brown, traversed by blackish 
lines, and margined by white dots; a black discocellular dot ; 
external border blackish, diffused ; two or three whitish sub- 
apical dots ; secondaries silvery-grey, with a darker waved cen- 
tral belt, formed of parallel dark grey lines, dotted with black 
upon the abdominal margin, white bordered ; a submarginal 
series of white-bordered grey spots ; a marginal series of blackish 
dots in pairs ; fringe pale yellowish-brown ; abdomen with dor-
