50 Lord Walsingham on Western 



indented above vein 5. Neuration, 12 veins, all separate ; 2 from 

 commencement of outer third of cell, 3 and 4 somewhat straight, 8 

 to termen. Hind wings broader than the f orewings (or at least equal 

 to the extreme width outwardly), evenly rounded. Neuration, 8 

 veins ; 3 and 4 from a point or short stalk, 6 and 7 from a short 

 stalk, 8 free, 5 straight ; outer edge of cell somewhat receding 

 upwards. Legs, hind tibiae slightly hairy. 



Allied to Hilarograplia , Z., but differ ing in vein 8 of 

 the forewings running to the termen instead of to the 

 costa, in the much straighter costa and in the conspicuous 

 indentation between veins 5 and 6. 



Tdiothauma africanum, sp. n. (PI. II., fig. 9.) 



Antennae ochreous with greyish cilia. Palpi pale straw-colour. 

 Head brownish fuscous, with some pale straw-coloured scales. 

 Thorax brownish fuscoas, streaked at the sides with pale straw- 

 colour. Forewings reddish orange, streaked with brownish fuscous, 

 dark fuscous, pale straw-colour and metallic lilac ; the ground- 

 colour of the basal third is brownish fuscous, in which are two con- 

 spicuous pale straw-coloured marks, the one from the middle of the 

 base depressed along the fold, thence tending upwards and attenu- 

 ated to a sharp point below the costa at about one-third the wing 

 length ; the second at one-third of the dorsum, cuneiform, oblique, 

 and ending in a point at about the middle of the discal cell 

 immediately beyond the apex of the basal streak already described ; 

 separated from the outer edge of this mark, by a narrow line of 

 brownish fuscous, is a rather narrow band of shining cupreous- 

 scales illuminating the orange ground-colour of this portion of the 

 wing, this is entirely narrowly margined with brownish fuscous, its 

 upper extremity being above the middle of the k wing, but not 

 reaching to the upper edge of the discal cell, and therefore ter- 

 minating before the apex of the pale straw-coloured wedge ; a 

 dark fuscous shade leaves the dorsum at two-thirds from the base, 

 tending outwards to the end of the cell above its middle, its upper 

 portion contains a short orange streak and its extremity is con- 

 tiguous with a shade of a similar colour which approaches the 

 lower half of the termen extending to the tornus ; between these 

 two shades a short cuneiform spot of brilliant cupreous scales 

 leaves the dorsum immediately before the tornus, occupying the 

 central portion of the orange patch of which they form the 

 boundaries ; along the costa are seven pale straw-coloured streaks,
