Neachandella gen. nov. (fig. 612) 
Head with appressed scales. Ocellus posterior. Proboscis absent. Antenna 
i l 5 , in the male filiform, minutely ciliated, scape moderately elongate, 
flattened, without a pecten. Labial palpus long, median segment sub- 
ascending, dilated with appressed scales, rougliish below', slightly flattened 
laterally, terminal segment under 1, ascending, smooth slender, pointed. 
Maxillary palpus minute, drooping. Thorax without a crest. Posterior 
tibia with fine long appressed hairs above. Fore wfing lanceolate, pointed, 
without raised scale-tufts; lb furcate, lower edge of the cell w'eak, 2 weak, 
from 5 / e , 3 from angle, 3—5 remote, equidistant and parallel, discoidal 
vein strongly inwardly oblique betw een them, vertical above vein 5, 6 from 
the angle, to the termen, 7, 8, 9 out of 6, tolerably equidistant and parallel, 
7 to costa, 10 remote, 11 from beyond the middle; a short fringe of scales 
along the basal part of the upper edge of the cell directed upward, and 
one above the basal part of vein lb, directed downward. Hind w'ing over 
1 / 2 , lanceolate, with a distinctly prominent costal shoulder; 2 separate, 
simple, from the base to the termen at the middle of the wing; the media 
as a single vein from the base to the termen below' the apex, vein 3 out 
of the media beyond the middle of the w ing, 4 absent, 5 absent, 6 out of 
the radius halfway between 3 and the termen. 
Genotype Neachandella desis spec, nov., male. 
A novel form of great interest as it combines the characters of two 
families: the fore wing is of a true Cosmopterigid type, w'hile the hind 
wing shows a strong reduction of neuration along the lines known in the 
family Metachandidae, but this reduction, apparently, has proceeded 
along these fines even further than in that family itself.
