mould, in any case not pectinate) . Thorax light brown, mixed with 

 white. Legs (especially the foreleg) partly iufu seated. Abdomen 

 light brown-grey. 



Forewing white, glossy, but not so intensely as in the nitidula 

 group ; no markings except two slender (scarcely over - 5 mm.) brown 

 bars, both slightly roughened at their edges, or at least tending to be 

 feebly dentate outward on the veins ; first from SM' 2 at 35 mm. from 

 base, very oblique to cell-fold near end of cell, then slender along the 

 fold to the cross-vein, where it forms a small, irregular spot ; second 

 from SM 2 at tornus, very slightly curved in the opposite direction to 

 termen, ending in a point at SO close to apex ; fringe concolorous. 

 Hindwing light brown-grey, unmarked ; fringe white. Forewing 

 beneath smoky, the lines traceable ; fringe white. Hindwing beneath 

 as above, or very slightly paler.

Superficially very near Irene Prout, which has the antenna pectinate 

 with branches about two-and-a-half times diameter of shaft.

 GEN. MICEOLIGIA Warr. 



17. MICEOLIGIA INTERVENATA, sp. nov. 



J. 30 mm. Structure about as in dolosa Warr. (Nov. Zool. iv, 

 124), face perhaps less strongly tufted (but somewhat abraded), wings 

 slightly longer and narrower. Face brown, white below. Palpus 

 mixed brown and white, the white predominating below. Vertex 

 white. Thorax and abdomen white, mixed with brown. 



Forewing glossy white, with light brown markings, consisting of 

 more or less broad, chiefly interneural, longitudinal streaks ; first 

 streak subcostal, almost reaching the costal margin from the end of C 

 to SO 3 , where it terminates ; second streak commencing beyond middle 

 of cell, becoming trifid distally, the first branch running between E 2 

 and E 3 , the second between E 1 and W, the third obliquely forward to 

 termeu near apex ; two shorter streaks between E 3 and M 2 , reaching 

 termen ; a long one behind M and M 2 from base to termen, tapering 

 posteriorly, another branching from this at base and running behind 

 the fold and another close to hindmargiu (behind SM 2 ). Hindwing 

 pure white. Forewing beneath pale brownish, the white parts of upper 

 side weakly indicated. Hindwing beneath white.
