19. Aerotypia pleurotella Wlsm. <6. 
Labial Palyr porrect, nearly four 
times as long as the head; median joint slightly bent over, clothed above and below with long appressed 
scales; terminal joint half as long as the median, slightly clothed, smooth. Mazillary Palpi minute. 
Haustellum strongly developed, smooth. Ocelli absent. Head and Thorax smooth. forewings narrow, 
elongate, costa and dorsum paraliel, apex obtusely pointed, termen oblique, evenly rounded: neuration 
12 veins; 7-8 stalked, to costa; 6 approximate to 7; 5 remote from 6, approximate to 4; 3-4 closely 
approximate; 2 from outer fourth of cell; 1 basally furcate. Mindwings broader than forewings, 
termen oblique, subsinuate, tornus evenly rounded: neuration 8 veins; 6-7 approximate at base, 
thence diverging ; 3-4 connate, or short-stalked; 5 cubital, nearer 6 on termen than on discoidal which | 
is bent inward between them ; 12 anastomosing with radius at middle of cell, thence diverging, straight. 
Abdomen and Legs smooth. 
A peculiar genus, of which the ? is unfortunately unknown and consequently its 
relationship is obscure. The porrect palpi of the ¢, and the anastomosis of HW: 12 
with the radius, should render it easy of recognition. 
1. Aerotypia pleurotella, sp.n. (Tab. III. fig. 3:) 
Antennae and Palpi pale ochreous, Head and Thorax whitish ochreous; the tegulae streaked with darker 
olivaceous ochreous. Forewings ochreous, fading to ochreous white from below the middle to the dorsum: - 
from the base below the costa to the apex runs a straight white streak of even width throughout ; above 
it the ochreous ground-colour is tinged with pale olivaceous fuscous to the costa, as also narrowly along 
its lower margin, making it very clearly defined; cilia whitish, tinged with ochreous, especially at the 
apex and on the costa; underside fuscous, with cream-white cilia. Fp. al. 40-42 mm. Hindwings 
sericeous, pale brownish fuscous, tending to fade to paler from costa to dorsum; cilia whitish with a 
faint ochreous tinge; underside fuscous, with cream-white cilia, Abdomen very pale brownish fuscous 
Legs creamy whitish, shaded above with pale brownish fuscous. )
