prismatic green and purple reflections occupying whole of disc from near base 

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

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

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

 ochreous round dorsal patch,

 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 Piatyppplus, as previously explained. I find further that the 

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

 Enarmoma 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, atti-ibutmg 

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

 foiu" 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 3B 

 more, and have still much additional material. 

 Argyroploce lasiandra, n. sp. 



$. 21 mm. 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 tibiee 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 

 and clothed with dense long hairs, toinus distorted and tufted with long pro- 

 jecting scales ; fuscous, somewhat suffused with light brownish-ochreous in and 

 beneath disc ; cilia pale greyish-ochreous, with suiiused fuscous sabbasal shade. 

 Trincomali, Ceylon, in November (Green) ; one specimen. 

 Argyroploce ionsoria, n. sp. 



^. IG mm. Head, palpi, and thorax pale brownish-ochreous irregularly 

 sprinkled with dark fuscous, palpi subascending. Abdomen grey, apex rosy- 

 tinged. Posterior tibife and basal joint of tarsi densely tufted above with long 

 expansible whitish hairs. Forewings moderately elongate, rather dilated pos- 

 teriorly, costa gently arched, apex obtuse, termen rounded, little oblique ; 

 brownish-ochreous suffused with ochreous-whitish ; basal third irregularly 

 mixed with yellow-brown and sprinkled with black ; a yellow-brown triangular 

 patch extending on costa from middle to near apex, its apex nearly reaching 

 dorsum beyond middle, much mixed with black posteriorly, costal edge marked 

 with five pairs of white strigulae ; a yellow brown streak along upper part of 

 termen, confluent above with triangular patch, preceded above middle by
