inner edge scarcely sinuate, its outer edge slightly irregular, with 

 a projection on the fold, between two brownish fawn spots, not 

 detached from the bright fawn portion of the wing beyond it ; the 

 white fascia is also projected narrowly along the costal margin to 

 the apex ; the costal cilia tipped with fawn-yellow ; the cilia on 

 the apical margin wholly fawn-yellow. Hind wings and cilia 

 very pale fawn. Abdomen and legs pale fawn. Exp. al. 12 mm.

Lithocolletis zulella, Wlsm. 



I have no longer access to the type of this species, 

 which is in the Cape Town Museum ; but, from my 

 recollection of the shape of the hind wings, and from the 

 figure, I am inclined to believe that it belongs to Oxy- 

 machceris rather than to Lithocolletis. 



MICROPOSTEGA, gen. n. ^ <*j-<A 

 os = little ; Opostega (nom.^gen). 

 Type. Micropostega csneofasciata, Wlsm. 



[PL vii., fig. 90.] 



Antennae as long as the fore wings, simple; basal joint enlarged 

 and clothed with a well-developed eye -cap. Maxillary palpi short, 

 drooping. Labial palpi also drooping, cylindrical. Head much 

 flattened, with a strong radiating frontal crest ; face smooth. Fore 

 wings rather wide, somewhat dilated from the base outwards, the 

 costal margin slightly indented before the apex, apex rounded, cilia 

 long. Neuration 5 veins ; discal cell open ; 2 and 3 from a 

 common stem, as also 3 and 4. Hind wings very narrow, elon- 

 gate, acuminate, evenly attenuated throughout, cilia long. Neura- 

 tion with vein 1 near the base, and a single median vein forked at 

 the apex. Abdomen flattened. Legs strongly tufted above. 



This genus differs from Opostega in neuration, as well 

 as in the flattened and highly crested head, and in the 

 somewhat less developed eye-cap.
