MICROLEPIDOPTERA OF NEW GUINEA 
Male genitalia show no differences from those of the typical form. (Slide 
no. 891 D, type.) 
Sigi Camp, 1500 m, February 19, 1939. One specimen. 
Arignota Turner, 1897 
Arignota Turner, 1897, Ann. Queensl. Mus., vol. 4, p. 21. Fletcher, Mem. 
Agric. Ind., Ent., vol. 11, p. 23, 1929. 
Head with long, loosely appressed scales, forming a roughish tuft over 
the face. Ocellus absent. Proboscis absent. Antenna in the female 2 / 3 , 
serrate, each serration with a minute fascicle of cilia at the apex, or fili- 
form, minutely ciliate; scape moderately elongate, robust, with a small 
triangular scale-tuft at the apex beneath. Palpus moderately long, ascend- 
ing, curved only at the base, median segment reaching just above the 
base of the antenna, or not reaching this; median segment moderately 
thickened with long smoothly appressed or rather rough scales, loose 
towards the apex, terminal segment about 1 / 3 of the median or less, rather 
robust, acute. Thorax stout, broad, with very long loose hairs (damaged 
posteriorly; with a crest ?). Abdomen stout. Anterior tarsus somewhat 
over 1, not thickened, clothed above with dense, closely appressed long 
scales, not reaching the apex, median and posterior legs long-hairy above 
and beneath. Fore wing without scale-tufts, lb long-furcate, 2 from beyond 
4 / s , 3 from the angle, 3 — 5 equidistant, remote, 7 and 8 stalked, 7 to the 
apex, 9 approximated to the stalk, 1 1 from beyond the middle. Hind 
wing rather short, semiovate, l x / 4 , cilia about 1 / 10 , 2 from s / 5 , 3 and 4 
short-stalked from the angle, 5 gently curved, moderately approximated, 
6 and 7 closely approximated at the base, 8 connected with the upper 
edge of the cell by a very short transverse bar at 1 / 3 of the cell. 
This redescription is based on the characters of the female specimens 
of the following species, and differs in a few respects from the original 
description by Turner. These differences are immaterial, in our opinion, 
and may be caused by sexual dimorphism as the genus is originally 
described after a male specimen. Our species differ from the genotype, 
A. stercorata (Lucas) by minute ciliations of the antennae, shorter terminal 
segment of the palpi ( x / 3 or less, instead of x / 2 ), not thickened anterior tarsi, 
little approximated veins 3 — 5 in the fore wing (in stercorata closely 
approximated), and vein 11 originating from beyond the middle. 
Key to the Papuan species of Arignota 
1. Female with antenna serrate; cilia in fore wing pure white, with broad black 
bars decipiens spec. nov. 
Female with antenna simple; cilia in fore wing light tawny-fuscous with pale 
ochreous base, with broad black bars clavatrix spec. nov.
