Palpi short, hardly reaching beyond face. Antennae of S finely pectinated, 

 the pectinations ciliated, slender, ami nearly at right angles with the shaft : of ? 

 also pectinated, bnt shorter, the pectinations more ol)li(iae and not extetidiug to 

 apex : hind tibiae of <S normal, with a terminal pair of spurs ; of ? with fonr 

 spurs. 



Nettration : forewings, cell half the length of wing : the discocellnlar vertical : 

 the median and snbcostal veins l)oth bent inwards towards extremity ; first median 

 nervule at fonr-fifths, second before, third from end of cell ; lower radial from a 

 little above the centre of discocellnlar ; upper radial normal ; 7, 8, 9 stalked, from 

 before end of cell : 10 and 11 free, from cell ; 10 anastomosing with 11 and again 

 with 7, 8, 9, forming a double areole : 7 from apex of areole: S, 9, 10 long-stalked. 

 Hindwings with veins 7 and 3 both before angles of cell.

123. Isoplenia trisinuata sp. nov. 



Forewings : in S l)rick-red, or brownish red ; in the ? duller, greyer, densely 

 sprinkled with red atoms : the lines deep red ; first at one-third, bent below costa, 

 thence sinuous to inner margin ; second at two-thirds, angled inwards on snbcostal 

 and outwards on vein 6, thence sinuous and vertical to inner margin beyond two- 

 thirds : third angled outwards on vein 6, thence sinuous and wavy to just before 

 anal angle ; a more obscure zigzag subterminal line, its angles joined by reddish 

 streaks between the veins to the marginal Hue, which is finely red : fringe con- 

 colorons : cell-spot dark. 



Hindwings : the same, withont first line. 



Underside pale pinkish ochreous, with the two outer lines shown. Face and 

 palpi deep brown : verte.x and antennae red : thorax and abdomen like wings. 



Expanse of wings : c?, 26 mm.; ?, 32 mm. 



Three t?cf, two ? ?, from Weenen, Natal ; two 6S and one ? dated December 

 1893, the other pair March 1894 ; in both cases the SS much fresher and in 

 better condition than the ? S . 



Leptacme gen. nov. 



Forewings : elongated, the costa straight till close to apex ; apex produced, 

 somewhat acute ; hindmargin slightly sinuous, very obliquely curved below, the 

 anal angle rounded off. 



Hindwings : slightly protuberant at veins 6 and 4, incnrved between. 



Palpi and tongue almost obsolete : antennae of ? filiform : mid tibiae with one 

 pair of spurs ; hindlegs and abdomen wanting. 



Xeuration : forewings, cell nearly two-thirds of wing ; discocellnlar straight ; 

 first median from seven-eighths, second shortly before, third from end of cell : the 

 median nervure itself bent upwards towards the extremity of cell : radials normal : 

 veins 10 and 11 stalked : 7, 8, 9 stalked ; the stalks anastomosing, 11, 7, 10, 8, and 

 9 rising in the order given. Hindwings, with cell two-thirds of wing ;'the dis- 

 cocellnlar obli(iue ; the two subcostals on a very long stalk ; medians as in 

 forewings.
