fore wing. Both wings with very small black cell-spot. 

 Underside more brownish grey, dark-dusted, fore wing with 

 the costa spotted with dark, a vague dark narrow submarginal 

 band, most distinct on anterior half, followed at apex by an 

 ill-defined whitish spot ; hind wing similar, the apex not 

 whitened; both wings with the cell spot.

Notwithstanding its similarity in markings to several 

 other species of the group (commotaria, &c), its delicate 

 coloration gives this species a rather distinctive appearance. 



The venation varies slightly, SC 1 of fore wing anasto- 

 mosing with C in one only of the four. 



Odysia punctilineata (Warr.), ab. (?) extensafa, no-v. 



? . 41 mm. — Face dark fuscous, narrowly wood-brown at 

 base of antennas ; palpus and fore leg dark fuscous, the 

 femur and tibia pale on outer side ; head and thorax wood- 

 brown, with fuscous speckling ; abdomen dorsally fuscous, 

 with anal segments pa'er. Wings elongate. Fore wing 

 wood-brown, darkened with numerous tine fuscous speckles 

 and suffused with dull blackish before the outer line, the 

 suffusion extending basewards along submedian fold and 

 outwards beyond cell ; lines all very obscure and marked 

 mainly by black pale-tipped dashes on veins and submedian 

 fold ; the inner line double, oblique outwards and angled in 

 cell, then oblique inwards ; second line curved from costa 

 before middle, outer from three- fourths, approximated to 

 second line on inner margin ; subterminal marked by dark 

 pale-tipped lunules ; bhek marginal sputs between the veins ; 

 beyond them the paler fringe is chequered with dark. Hind 

 wing wiih the median space darker, especially along the 

 outer line j all the lines blacker and plainer ; the marginal

I have described this form fully and independently on 

 account of its different aspect, but I believe it will prove to 

 be a much darkened aberration (perhaps even the normal $ 

 form) of Odysia (?) punctilineata, Warr. Nov. Zool. vii. p. 198 

 (Stenalcidia), of which I possess the $ from the same 

 locality. In the paucity of generic characters in the large 

 group (Boarmia, sens, lat.) to which this species belongs, it 

 may be referred to Odysia, Guen.,= Isandria, Warr., to the 

 type species of which (0. molaria, Guen. } = ineffectaria t
