Mtostoma stbaminea, sp. n. 



d' . Fore Avings very pale straw-colour, shaded with pale olive- 

 fulvous ; the lines darker ; 1st line at -J- of the costa, runs 

 outwards and is angulated below the costa, then runs obliquely 

 inwards to the inner margin at | ; exterior line at f , similar to the 

 inner hne ; space beyond to hind margin darker than the rest of 

 the wing ; a dark oblique streak from apex to the angulation of 

 the outer hne ; a slightly darker shade on the costa before apex ; 

 both transverse lines more strongly marked at their origin on 

 costa ; an irregular iudistmct pale submarginal fascia ; base of 

 fringes brown; fringes themselves pale straw; base of wing and

 cell-spot distinct and 2 very indistinct darker bands towards hind 

 margin ; underside the same, with the lines more distinct. Head, 

 thorax, and abdomen straw dusted with fulvous. 



Expanse of wings 26 millim. 



2 ' Wings dull straw-colour, finely dusted with fuscous ; cross 

 lines very indistinct, starting from dark brown costal flecks, and only 

 visible at the veins ; 1st irregularly vertical at |-, 2nd at |, strongly

 cell half the length of the wing ; discocellular vertical ; 1st median 

 nervule from | of the cell ; 2nd and 3rd together from the lower 

 end, the 3rd straight in the S , somewhat arched in the 2 ; lower
