somewhat wavy, with a fine black line ; discal spot small, black. Be-

Mesoleuca abacta, n. sp. 



Expands 34-36 mm. Palpi not heavy, moderately long, erect, almost 

 recurved, blackish ; front thorax and abdomen fuscous, more or less 

 stained with ochre ; abdomen tufted at end ; fore wings broad, light gray, 

 more or less striated crosswise with blackish ; basal line fine, distinct, 

 some angled at middle, sharply black ; one-third out another black line, 

 turned outward from costa, sharply angled on cell, thence running broadly 

 and heavily nearly straight to inner margin ; this is followed by a finer, 

 almost parallel line, which is somewhat broken on posterior half, a faint, 

 much broken black line just beyond discal spot, and beyond that a quite 

 heavy black line angled outward between 3 and 4, broken posteriorly ; a 

 clear black rounded spot costally at apex ; marginal line black ; discal 

 spots prominent, black, well out on wing. Hind wings fuscous, lighter 

 basally, becoming darker and with faint shadowy darker lines towards 

 outer margin and parallel with it; beneath fuscous, much the colour of hind 

 wings above, the fore wings becoming darker along costa and towards apex.

Hydriomena pernotata, n. sp. 



Expands 34 mm. Palpi rather short, sordid fuscous ; front of same 

 colour ; thorax fuscous gray, with black edging to patagife ; thorax dark 

 fuscous, black dorsally, lighter fuscous posteriorly on segments ; fore 

 wings rather long, grayish fuscous, broken up with irregular black spots ; 

 these on the basal half very irregular, so that the lines of which they are 

 the evidences are entirely indeterminate ; a whitish fuscous band beyond 

 discal spot, edged outwardly with a geminate broken, dentate, wavy, and 

 angled black line running in genera) direction, parallel with outer margin ; 

 a submarginal incomplete row of black dashes, the space having a bluish 

 stain. Hind wings light fuscous with an ochre reddish stain outwardly, 

 marginal line black, finely broken on all wings ; beneath rather deep 

 broken fuscous, becoming a large blackish spot towards apex ; hind wings 

 as above, but much darker ; the fore wings are also considerably ochre
