Hiiiduimjs : angled at veni o. the shorter portimi nt' hinilinarffiii In anal aiit^le 

 straight, the longer upper portion convex, the apex nmndefl. 



Palpi very short, not exceeding front of face; tongue very slight ; frenulum (?) 

 invisible; antennae (?) shoi'tly bipectinate ; hindtibiae with terminal spm-s oidy. 



Xeiinition: forewings, cell half of wing; discocellular concave, more obliipie 

 below; first median nervule at two-thirds; second and third shortly stalked; lower 

 radial from a little above centre of discocellular; upper from ujjper angle; 7, 8. !), 

 10 stalked from upper angle; 11 free : hindwings. (i and 7 from upper angle of cell ; 

 3 and 4 short stalked; costal touching subcostal siiortlv near base. 



Coloration quite unusual, being chalk-white witii dark atoms. 



'I'ype : Xcnochroma candvlata sp. nov. 



26. Xenochroma candidata sp. nov. 



Forewings: pure white, without any distinct (races of lim-s, but the marginal 

 half dusted with dark grey flaky scales; fringe white, with the tips in ajiical half 

 dark grey. 



Hindwings : the same, but with the cell-spot mai-ked witli grey, and slight 

 indications of a bent grey postmedian line. 



Underside white, with the tips of the apical fringes grey, and scattered giey 

 scales towards apex of forewings. Face, palpi, and forelegs dull vinous red ; rest of 

 head, thorax, and abdomen white. 



Expanse of wings : 26 mm. 



One ? from Kilwa, German East Afiica, March 1900 (Reimer). 



Although in fairly good condition, it seems probable that the basal [lortions of 

 the wings have had their scales rubbed off; on the forewings there are traces, 

 especially on inner margin, of antemedian and postmedian shades, and the cell-siiot 

 was probably grey like that of liitulwings.

 27. Craspedia agrapta sp. nov. 



Forewings: bone-colour, with very sparse blackish scales, and with a very 

 faint tinge of ochreous in places; cell-spot black, distinct ; lines grey, very obscure ; 

 median curved from three-fifths of costa to middle of iinier margin; outer from 

 four-fifths of costa to three-fourths of inner margin, indented beyond cell ; two 

 very faint subterminal shades ; marginal dots black, minute ; fringe glossy white ; 

 no basal line visible. 



Hivdwings: with black cell-spot, the median line concave before it; the rest 

 as in forewings. 



Underside white, slightly discoloured in the forewings. Face, palpi, and front 

 of forelegs throughout brown-black ; thorax and abdomen like wings. 



Exi)anse of wings : 27 mm. 



One d from the Escarpment, British East Africa, March lilOl (I)oherly).

28. Craspedia argentidisca sp. nov. 



Forewings: white, densely dusted with greenish grey; first line from one-1 liinl 

 of inner margin, oblique outwards to cell-spot, then obsoletely recurved to costa; 

 second from a little before apex, oblique inwards and from vein fi to inner margin
