﻿November 15, 1909.] Descrlplions of Indian Micro-Lepidoptera. -59?^ 



Thorax whitish-ochreous, anteriorly tinged with brownish and marked with 

 blackish-grey. Abdomen fuscous, basal third ochreous-yellowish,apex whitish- 

 ochreous. Posterior tibite beneath with long projecting ochreous scale, forming 

 a broad triangular tuft before middle and grey expansible hair-pencil from base 

 lying on inner side of this. Forewings elongate, moderate, posteriorly dilated, 

 costa gently arched, apex obtuse, termen somewhat sinuate, vertical, rounded 

 beneath ; rather dark brown tinged with reddish, mixed with blackish and 

 sufifusedly striated with ashy-grey ; a large semi-oval ochreous-whitish blotch 

 extending along costa from 5 to § and reaching nearly half across wing, mark- 

 ed with indistinct pale red-brownish oblique striguls becoming distinct and 

 blackish on costa, and a light brownish oblique costal spot in middle ; and 

 ashy-grey fascia indistinctly edged with whitish from beyond this blotch in 

 disc to ^ of dorsum, followed by some undefined whitish suffusion towards 

 termen : cilia pale fuscous sprinkled with whitish, with two dark grey shades, 

 Hindwings dark fuscous, with bases of scales subhyaline, appearing finely 



8tria,t§d ; a l arge patch of rather thinly strewn modified black hairsca,les with 



prismatic green and purple refl^ections occupying whole of disc from near base ^/ 1>^' 



to f ; whole dorsal area beneath this yellow-ochreous, towards dorsum clothed 

 with long dense scales and with dorsal cilia elongated, on lower surface with 

 expansible long hairs in a subdorsal groove ; cilia as in forewings, becoming 

 ochreous round dorsal patch, 



Maskeliya, Ceylon, in April (Pole) ; one specimen. The special colouring 

 and structures of hindwings will doubtless prove to be confined to the ^. 

 Argyroploce, Hb. 



I agree with Prof, Fernald in adopting this name for the genus previously 

 termed by me Eucosma, Hb, (that name being rightly applied otherwise), 

 including also Piatypeplus, as previously explained, I find further that the 

 stalking of veins 3 and 4 of hindwings cannot be properly used to distinguish 

 Enarmonia generically, since in some of the species hereafter described the 

 structure is inconstant within the limits of the same species, and I propose 

 therefore to rely on the thoracic crest to separate the two genera, attributing 

 all those species with well-developed crest to Argyroploce ; on this view the 

 four Indian species already referred to Enarmonia must all be transferred tO' 

 Argyroploce. On this understanding the number of Indian species already 

 described which are attributable to Argyroploce is 28, and I now describe 3S 

 more, and have still much additional material. 

 Argyroploce lasiandra, n, sp. 



^. 21mm. Head, palpi, and thorax rather dark fuscous, palpi porrected. 

 Abdomen light greyish-ochreous, dorsally clothed with dense rough hairs, and 

 with large expansible anal tuft. Posterior tibiae and basal joint of tarsi clothed 

 with dense long rough greyish-ochreous scales above. Forewings moderate, 

 posteriorly dilated, costa gently arched, apex obtuse, termen slightly rounded, 

 oblique ; dark grey, strigulated with blackish, tips of scales fuscous-whitish ; cilia 

 concolorous. Hindwings reduced, narrower than forewings, dorsal area folded
