307. Microsema flexilinea spec. nov. and ab. nubilata nov. 



<$. Forewing : pale ochreons, generally covered with fine linear brownish 

 striae and dusted with coarse black speckling ; lines brown-black ; first at one-third, 

 bracket-shaped, angled in cell before the black cell-spot, and again on snbmedian 

 fold ; the extreme base sometimes rather darker ; outer line from costa just before 

 apex to two-thirds of inner margin, always with a slight bend outwards in middle 

 and edged by a fine pale line ; fringe concolorons. 



Hindi/ring : with costal area paler ; the line central, just beyond cell-spot. 



Underside whitish ochreons, with sparser speckling ; lines as above, but thick ; 

 that on hindwing faint, joined on inner margin by a fine dentate-lunulate line 

 running to costa before apex. 



Head, thorax, and abdomen like wings. 



? paler ; the outer line triple, the line itself fine and marked by dots on the 

 veins, preceded by a brown line and followed by a pale one as in the e?. 



Expanse of wings : <? 30 — 33 mm. ; ? 40 mm. 



The aberration nubilata has the central area beyond inner line filled in with 

 a diffuse fuscous-brown cloud. 



5 <S<$, 1 ? from Sapncay, Parguay, July— December 1901—1904 (Foster). 



Of these 2 c$S represent the aberration. 



308. Mimosema venata spec. nov. 



Forewing : pale fawn-colour, speckled with fine dark atoms ; the veins all 

 finely dark ; costal edge red ; lines thick, red-brown ; first oblique outwards from 

 about one-fourth of costa to middle of inner margin ; outer straight from three- 

 fourths of costa to four-fifths of inner margin ; a red-brown oblique streak on 

 discocellnlar ; marginal line finely dark ; fringe concolorons, red at base. 



Hind winy : with the outer line only, from three-fourths of costa to anal angle ; 

 discal mark as in forewing. 



Underside dull whitish, speckled with grey, most thickly in costal half of 

 forewing and towards apex ; outer line aud cell-spots hardly marked. 



Head, thorax, and abdomen like wings. 



Expanse of wings : 30 mm.

309. Mychonia brunnea spec. nov. 



Forewing : rufous ochreons, speckled with grey ; costal edge white with black 

 dots ; lines brown ; first at one-third, bent below costa and slightly oblique 

 outwards ; outer from three-fourths of costa to two-thirds of inner margin, forming 

 a bluntly rounded projection above vein towards outer margin, as in M. flexilinea, 

 then incurved and slightly waved, parallel to outer margin; at costa edged with 

 black scales, which extend along vein 7 to costa before apex, forming a rough 

 semicircle ; fringe dark brown with pale tips ; cell-spot blackish. 



Hindwing : paler, with the outer line only, sinuous, parallel to outer margin. 



Underside paler, especially in hindwing, the speckling darker; the lines all 

 marked : the outer line blackish at costa of forewing.
