MOTHS FROM SOMALILANU. 159 



dark grey, with a distinct, sinuous, whitish, subterminal line, 

 which is rather thick in places, and especially widens at costa so 

 as almost to reach apex ; proximally to the subterminal an 

 irregular blackish spot between E,'' and M\ sometimes also 

 anteriorly to R^ ; termen with a row of moderately thick blackish 

 dashes ; fringe weakly dark-chequered opposite the veins. Hind 

 wing with termen almost perfectly rounded, sometimes with a 

 slight suggestion of prominence at W and sinuosity in front of 

 the same ; similar to fore wing, without the antemedian line. 

 Fore wing beneath somewhat more suffused from base to median 

 shade ; discal dot weak ; the shade between postmedian and sub- 

 terminal strengthened into a dark band, without the blackish 

 spot, the subterminal itself obsolete ; band between median and 

 postmedian lines, also the posterior half of distal area (or at least 

 a patch behind E.^) somewhat whiter than above. Hind wing 

 beneath whitish, with median shade, discal dot and outer band 

 distinct. Female, on an average, rather larger, rather broader- 

 winged, sometimes more sufiused, lines generally weak (except 

 the costal spots), distal dark shade extended to termen, usually 

 almost obliterating the subterminal line except costally, where 

 the subapical pale spot persists, at least in part, black spot 

 proximally to subterminal line between R^ and M^ seldom 

 developed; the hind wing and under surface show corresponding 

 difi'erences.

Variable both individually and (in particular) sexually. More 

 recalls certain tropical American species (e. g. Macaria nigricomma 

 Warr. in the case of the male, heliothidata Guen. in that of the 

 female) than any African species with which I can compare it. 

 Scarcely a true Discalma.

1908: June 21,— Ic?. 



Antenna broken, but a remnant shows that the ciliation is 

 scarcely as long as the diameter of the shaft. Hind tibia strongly 

 dilated. Fovea strong. 



Founded on females from British East Africa.
