dull yellowish. Vertex, shoulders, and patagia i-ream-coiimr, uiispeekled ; tlinrax and 

 abdomen like wings. 



Expanse of wings : 30 mm. 



One ? from the Escarpment, British East Africa, Feliruary 1901 (Doherty). 



.■51. Craspedia natalica I'.utler ali. obliterata nov. 



Wint/s: dull wood-brown, not ochreous with a rufous tinge as in the type form; 

 more finely speckled and smoother in ajipearance ; no markings except the large 

 black cell-spots and the black marginal dots; merely a faint rufous cloud along the 

 ordinary course of outer line. 



Underside also without markings, but tinged through cell and along course of 

 outer line with vinous red scales; speckled throughout with black, and dark at base 

 of eosta. 



Expanse of wings : 30 mm. 



One S from the Escarpment, British East Africa, ]\Iarch 1901 (Doherty). 



I am not sure that this is not a distinct species; but as there was onh' the one 

 specimen, I have referred it provisionally to natalica as an aberration. 



Lissoblemma gen. nov. 



Forewings : ample; costa well curved throughout, the apex hlunt, slightly pro- 

 duced; hindmargin faintly sinuate. 



Hindwinijs : with hindmargin well rounded, slightly indented before the anal 

 angle, which is square. 



Antennae of c? with short stiff pubescent pectinations for three-fourths, the 

 shaft, strongly serrate beneath, the serratures alternating with the pectinations. 

 Palpi porrect, reaching well beyond face, first and second joints rough-scaled beneath, 

 terminal joint short; tongue and frenulum present. Hindlegs much aborted, the 

 tarsi quite short, the tibiae hardly swollen, with a pencil of hairs from base. 



Neuralion : forewings, cell not quite half as long as wing; discocellular vertical 

 above, obliquely curved below; first median nervide at four-fifths, second close before 

 third ; lower radial from just above middle of discocellular, upper from upper angle 

 of cell ; subcostal vein shortly bent downwards at end, veins 7, 8, 9 stalked from the 

 bend ; 10 close before them, anastomosing with 11 and again with 7, 8, 9, forming a 

 double areole : hindwings with veins 3 and 7 close before angles of cell. 



Type : Lissoblemma viridifusa sp. nov. 



Somatina luntdiferata Wlk. (Becetia) will also come into this genus. 



32. Lissoblemma viridifusa sp. nov. 



Forewi/ngs: dull lilac-grey, with ]iartial olive-green suffusion; costal edge 

 narrowly red; lines dark grey, irregularly dentate-lunulate ; first from about one- 

 fourth of costa to one-third of inner margin, marked by a black spot from costal to 

 subcostal vein ; median line fi-om beyond middle of costa to middle of inner margin, 

 incurved below discal mark, which is linear, shining pale grey, with darker edging; 

 outer line blackish, finer and more distinct than the others, dentate hasewards on 

 the veins, irregularly lunulate outwards, followed by an olive-green diffuse shade ; 

 submarginal line indistinct, irregularly waved, and apiiroximated to margin, the 

 marginal space beyond it somewhat darker grey ; marginal line continuous, blackish ; 

 fringe pale grey.
