Mixocera gen. nov. 



This new genorii" name is proposed for two or three species differing from 

 Nemoria on tlie one hand, and Microlouia Warr. on the other, in the strncturo of 

 the (J antennae. The shaft is broadened and flattened, armed along the basal half 

 with short claw-shaped fascicles of cilia in place of the pnbescence of the one and 

 the full jiectinations of the other. In the forewings veins C, 7, 8, 9, 10, 11 are all 

 stalked from the upper end of cell, 11 anastomosing and sometimes becoming 

 coincident with 12. Fronnlnm absent. 



Tj'pe : M. indecretuta Wlk. Latilineuta Wlk. from Australia, and scrraticornis 

 Warr. from Africa, also belong here, as well as the following new species. 



10. Mixocera albimargo sp. nov. 



Like M. hitilincatd Wlk. from Australia, bnt with an additional white marginal 

 streak to both wings ; fringe white. 

 Expanse of wings : 17 mm. 

 1 (J from Ogrngu, Amambara River, Lower Niger. 



Pycnodontia gen. nov. 



Forewings : elongate ; costa slightly curved ; apex prominent ; hindmargin 

 oblique, slightl}' curved. 



intuhcinijs : with hindmargin well rounded ; anal angle well marked. 



Palpi short, porrect, not reaching beyond foreliead : antennae of c? lamellate, 

 with short, broad, clavate teeth : tongue and frenulum jiresent ; hind-tibiae with 

 four stout and approximate spurs. 



Neumtion : forewings, cell nearly half as long as wing ; discocellnlar oblique 

 inwards .above, outwards below ; first median nervnle at three-fourths, second close 

 before third ; lower radial from upper two-thirds of discocellnlar, upper from upper 

 angle of cell ; 7, 8, 9, lo, stalked from the angle ; 11 free, approximated to 1'.^ ; 

 hindwings, costal shortly touching subcostal near base ; and 7 stalked ; medians 

 as in forewing. 



Type : Pycnodontia apicata sp. nov. 



Characterized by the structure of the 3 antennae. 



11. Pycnodontia apicata sp. nov. 

 Forewings : pale green, without markings ; fringe pale green. 

 Hindwings : the same ; fringe in the apical half tinged with brown-grey. 

 Underside whitish green ; base of costa of forewings reddisli ; face, palpi, and 



forelegs vinous red ; head, thorax, and abdomen like wings ; antennae ochreous. 

 Expanse of wings : 34 mm.

The types, both from Warri, differ both in the shajje and coloration of the 

 markings ; the colour of the blotches being red-brown in jmlliata, and black-brown 

 in ustipennis, while the extent of the blotches is much greater in the S than iu the 

 ?. I have now seen another cj, from Sierra Leone, which agrees in coloration with
