submedian veins pearly opaline ; costa washed with buff; an 
ill-defined transverse dusky discal stripe; external area pale 
rosy cupreous: secondaries sericeous whitish, the costal area, 
veins, and fringe buff, slightly rufous; a discocellular spot 
and five or six longitudinal dashes on the veins across the 
disk black: pectus whity-brown; legs rufous-brown, with 
ferruginous spines and whitish-tipped spurs; venter rosy, 
with the anal tufts slightly yellower. 
Expanse of wings 43 millim. 
One male of this very distinct species. 
4. Peridroma hostilis. 
Agrotis hostilis, Walker, Lep. Het. xi. p. 737 (1857). 
Four examples. 
I believe that this is no more than an extreme form of 
P. saucia. FP. stictica, Blanch., from Chili, is quite inter- 
mediate in character between the two. 
5. Peridroma clerica. 
Agrotis clerica, Butler, Trans. Ent. Soc. 1882, p. 129. n. 27. 
Three examples of this Chilian species. 
6. Leucania falklandica, sp. n. 
In marking somewhat intermediate between L. s¢nuosa of 
India and L. propria of New Zealand. Primaries above 
sericeous whity brown, the course of the median vein and the 
external borders suffused with grey ; a black dot followed by 
a blackish spot at base of costal area ; a diffused black streak, 
trisinuate in front, immediately above the median vein, ter- 
minating beyond the cell in a small oblique 3-shaped 
character ; a well-defined black streak from base below the 
median vein, terminated by the extrabasilar line, which is 
much interrupted, transverse, and lunulated ; a blackish dash 
on the inner margin also followed immediately by the same line; 
discal or postmedian line fine, arched inwards to costa, dentate- 
sinuate ; a slightly irregular submarginal series of blackish 
sagittate spots ; fringe white, traversed by two grey lines: 
secondaries white, slightly opalescent, the costal area silvery ; 
veins and a rather narrow diffused external border smoky 
grey ; fringe white, traversed internally by a smoky grey 
line: head and thorax whity-brown ; collar greyish white, 
crossed at the back by an interrupted black line; tegule 
whitish at their apices; base of abdomen whitish buff, the 
remainder sericeous smoky greyish. Primaries below silvery
