straight transverse bar formed of 4 contiguous spots (of 

 which the 1st is largest and the 4th smallest and less dis- 

 tinct than the rest), extending from just below 2nd sub- 

 costal nervule, not far from apex to 1st median nervide, 

 not far from its origin. Underside. — Hindwing and 

 apex of forewing very variable in tint and clouding ; the 

 prevalent ground-colour being glossy-grey, irrorated and 

 hatched with black and fuscous. Foreioing : paler than 

 on upperside, the bars and spots larger ; discoidal cell 

 filled by much enlarged and united bar and spot ; a small 

 whitish spot immediately beyond upper part of extremity 

 of cell ; 2nd and 3rd spots of sub-apical row united in one 

 crescent-shaped marking. Hindwing : in two specimens 

 the upperside costal spot and discal bar represented by 

 2 irregular whitish transverse rays, interiorly broadly 

 bordered and in parts intruded on by dark-brown clouding 

 — a similar patch of the clouding being present on hind- 

 margin about extremity of radial nervule ; in a third 

 example, only the whitish ray near base is indistinctly 

 represented, while the whole discal region and lower half 

 of discoidal cell (up to base and a straight line through 

 the cell) is dull fuscous-brown ; and in the fourth example 

 the whole surface is almost uniformly grey, the rays being 

 faintly shown by a glossier paler clouding, and the inter- 

 mediate parts by some ochreous tinting — at extremity of 

 cell an ill-defined blackish spot. 



$ . Similar to $ , except that the markings generally are 

 larger, especially the bar across hindwing. Underside. — 

 More uniform than in $ , and nearly resembling that of 

 the 4th $ example above described, but ivith a decided 

 glaucous-green tint both in hindwing and in apical region 

 of forewing ; any trace of paler bars in hindwing being 

 obsolete, or nearly so. 



In the $ the fore wings are more prolonged apically 

 than in the ? ; but the hindwings are alike in both sexes, 

 the costal prominence beyond middle being very slight, 

 while the projection at the extremity of the 1st median 

 nervule is very well developed, forming a broad tail or 

 process j^ inch in length. The palpi of the ? are longer 

 and more attenuated than those of the $ . 



This Lihythea is very nearly allied to L. Labdaca, 

 Westw., a native of Sierra Leone, which is only known 

 to me by the description and figure in the " Genera of 

 Diurnal Lepidoptera" (vol. ii. p. 413, note, pi. Ixviii. 

 f. 6). The South African form may, however, be readily
