56. Tephroclystia immensa sp. nov. 



Forewimjs: fuscous, the markings suuii-what darker, l)ut oliscuie ; the usual 

 dark lines cross the wing, marked on the costa as alternate darker and lighter streaks; 

 the bands preceding and following central fascia are slightly paler; the cell-spot is a 

 large button of raised black scales, preceded bv a black line along the fold; the only 

 distinct marking is the part of the outer line and following band beyond the cell, 

 the outer line being there marked in black, and the ban<l paler with a black line 

 through it; submargina! line pale, indistinct; marginal line blackish, interrupted at 

 the veins; fringe fuscous. 



I[i)i(lu'iii(/s : dull grey, tlie markings visible only along inner margin. 



Underside dull cinereous in the forewings with faint indications of lines; 

 hindwings pialer, with cell-spot, curved median line, and broad submarginal shade. 

 Head, thorax, and abdomen fuscous; lace and palpi darker. 



Kxpanse of wings : ,35 mm. 



Two S(S, one ?, from the Escarpment, British East Africa, Septenjber 1900 — 

 January 1901 (Doherty). 



One of the largest of the Tephrodyslide, at first sight reminding one of some of 

 the species of the American genus Exelis. 



57. Tephroclystia nigribasis sp. nov. and al>. carnea nuv. 



Foreiviiifjs : white; the markings velvety Ijlack, or brown speckled witli lilack ; 

 basal patch large, outcurved below median vein, black, brown, or grey-speckled, with 

 two or three waved cross-lines; outer line at three-fiftl)s, oblique outwards to vein G, 

 black, incurved beyond cell and angled again on vein 3, raiely black-marked there, 

 jireceded by two parallel lines, all three sometimes interrujited by the white ground- 

 colour in cell and on submedian fold, more often waved and dotted on veins; 

 submarginal line whitish, waved; costal space before it and the extreme apex dark, 

 sometimes velvety black and large, or brownish ; the white ground-colour generally 

 extending obliquely to hindmargin between veins 3 and 4; marginal area brown; 

 marginal line black; fringe shining white, variously mottled with brown. 



Ilinilwiivjs : whitish grey, becoming dark grey along hiiiduiargin, and showing 

 a pale waved submarginal line ; other lines only visible shortly along inner margin ; 

 cell-spot small. 



Underside of forewings cinereous or brownish cinereous, the lines and markings 

 black and distinct only near costa ; hindwings whitish dappled with dark grey, the 

 veins spotted with black. Head, thorax, and abdomen dark, varying according to 

 the coloration of wings. In the S the abdomen is elongated and the anal segment 

 ringed at base with white. 



P'xpanse of wings : S 2fi mm. ; ? 28 mm. 



The extent of white ground-colour, which is mainly confined to the ? ? , is 

 variable, the whole inner margin sometimes being broadly brown. In some cases 

 (SS) the whole wing is suffused with flesh-colour, and the lines and markings 

 beyond basal patch become ob.solete, except the black costal blotches at apex and a 

 smaller patch at anal angle; to this form I give the name cm'iiea. 



58. Tephroclystia picturata sp. nov. 

 Forenvings : pale silvery grey, dusted with darker; basal patch ill-drtim'd, its 

 outer edge forming a bent rufous-brown fa.scia ; central fascia pale grey at inner
