to the Liiidmargin, the second and third appearing furcate towards costa ; fringe 

 white, with dark gre)' basal line, thickened above and marked with grey blotches 

 between the veins. 



Hindwiiigs : with inner margin broadly grey and with three grey streaks, one 

 from near base of costa towards anal angle, the second from middle of costa to half- 

 way between anal angle and tooth ; the third from before apex, slightly curved and 

 denticulate, joining the second before hindmargiu ; the black marginal line swollen 

 above the tooth into black spots at end of veins; a black dash in tooth, a large black 

 spot before it and another on vein 3. 



Underside uniform grey. Face and palpi black ; vertex white ; thorax dark grey ; 

 abdomen white, grey-tinged. 



Expanse of wings : J, 58 mm. ; ? , 02 mm. 



The ? is paler, less densely strigulated ; the underside of forewings with the 

 margins white ; of hindwings wholly white, except the costa. 



The (J agrees with M. sinuosa in haxing the hindmargiu of forewings indented 

 below apex and above anal angle, the submedian vein of forewings sinuous. In the ? 

 the hindmargiu of forewings is indented only below apex, the rest being slightly 

 convex. 



One f? from Penungah, December 1893 ; one ? from Kina Balu, North Borneo. 



31. Micronia sinuosa sp. nov. 



Foreiviwjs : dull white, covered with thick greyish ochreous strigulations ; two 

 oblique greyish ochreous streaks parallel to hindmargiu, from inner margin beyond 

 middle and at four-fifths, the first thicker, especially on the inner margin, both 

 becoming obsolete before costa ; fringe white, with a concise brown-black line at base ; 

 hindmargin shortly indented just below apex, and more broadly above anal angle. 



Hindwings : with a cm-ved central and curved and denticulate submarginal 

 ochreous shade ; some more uniform ochreous strigulae befoi-e hindmargin ; fringe 

 ochreous white ; the basal black line much swollen opposite the veins above the tooth, 

 less so below it ; a black dash in the tooth and a large black spot before it ; an 

 additional, but smaller, black spot on vein 3 before the margin. 



Underside uniform dark grey ; fringe of forewings white, of hindwings greyer. 

 Face and palpi black ; thorax and abdomen white. 



Expanse of wings : 54 mm. 



One S from Palawan. 



Differs from M. acideata in the neuration : veins 2, 3, 4 of forewings are not dis- 

 torted, but vein 1 is strongly sinuate. 



32. Pseudomicronia unimacula sp. uo\. 



Foreivings : white, the costa minutely strigulated with black ; the transverse 

 lines very pale ochreous, indistinct ; these are six in number, and are arranged 

 much as in Strophidia fasciata, each partially double and forking towards costa, the 

 outside one being a fine single line parallel to hindmargin ; fringe white, with a faint 

 basal line. 



Hindwim/s : with four oblique ochreous fasciae and two lines of striae along 

 hindmargin, curving into anal angle ; tooth with one large black spot ; marginal line 

 slightly swollen at the veins.
