EXOTIC MICROLEPIDOPTERA. 
AROTROMIMA, n. g. 
Head with appressed scales; ocelli posterior; tongue developed. 
Antennae f, S simple, faintly sinuate at base, scape elongate, with¬ 
out pecten. Labial palpi, very long, straight, porrected, second joint 
long, thickened with dense scales beneath and clothed with roughly 
expanded hairscales above, terminal joint short,'with appressed 
scales, obtuse. Maxillary palpi obsolete. Posterior tibiae clothed 
with dense rough hairs above. Forewings 1 b furcate, 2 from |, 3 
from towards angle, 4 and 5 closely approximated from angle, 6 and 
8 nearly approximated at base, 7 absent, 11 from beyond middle. 
Hindwings 1, trapezoidal, apex obtuse, termen hardly sinuate, cilia 
nearly 1; without cubital pecten ; 2 nearly from middle of cell, 
3 from near angle, 4 from angle, 5 rather approximated, 6 and 7 
connate. 
A peculiar form of doubtful affinity, the palpi quite abnormal; 
perhaps a derivative of the Glyphiclocera group. 
Arotromima politica, n. sp. 
c S . 14 mm. Head, antennae, thorax whitish. Palpi ochreous, 
becoming white towards upper scales and apex, basal third blackish. 
Forewings elongate, costa gently arched towards base, then nearly 
straight, rather abruptly bent at 4, apex obtuse-pointed, termen 
faintly sinuate, rather oblique; white, tinged grey on posterior 
third, darker near apex; costal edge blackish at base, some slight 
brownish suffusion beneath this; some brown suffusion along 
posterior half of costa ; stigmata indicated by faint greyish suffusion; 
three small black marginal marks round apex : cilia white, above 
apex with two short fuscous shades. Hindwings pale grey; cilia 
whitish.

costa gently arched, apex obtuse-pointed, termen rounded, rather 
strongly oblique; ochreous-whitish or whitish-ochreous, sometimes

blackish, plical obliquely before first discal, second discal rather 
large; a marginal series of rather elongate dark fuscous dots round 
posterior half of costa and termen : cilia whitish-ochreous. Hind¬

Phthorimaea microcasis, n. sp. 
Mr. T. Bainbrigge Fletcher has called my attention to the fact 
that the European Gelechia micradelpha Wals. (1900), now referred 
to Phthorimaea, is homonymous with the Australian Gelechia micra¬ 
delpha Low. (1897), and requires to be renamed; I therefore 
propose for it the name microcasis.
