One ? from the Ksciirimient. Kritish Kast Africa, March 1901 (Doherty). 



This seems quite distinct from S. iiikrjMsitd, described below. 



84. Scotopterix emunctaria. 



Boanitiii einnncturia (iueii. Plml. i. jj. 244 ?. 



This species, described by (iuenee from a single ? in poor condition, appears to 

 vary much in the same way as S. versicolur, described below. Among the insects 

 collected by M'. Doherty at the same time and place as IS. versicolor are twelve 

 e.xamples of the present species (7 d d, 5 ? ? ), of which the majority tally well with 

 Guenee's descrijition, except in being somewhat larger. One t? and one ? have the 

 central area very much paler, this being in the J satiny gi'ey with the edge whitish, 

 and in the ? dead white with the costa and median veins marked with greenish 

 scales. The species is distinguished from S. versicolor by the paler hindwings, with 

 a round dull cell-spot, and by the course of the outer line of the forewings ; this is 

 curved inwards from vein 5 to 1, whereas in versicolor it runs jiarallel to hindmargin 

 and onlv curves inwards in the submediau interspace. The markings arc generally 

 clearer in the d than in the ?. ' 



85. Scotopterix interposita sp. nov. 



Intermediate in some re.spects between S. einancturia Guen. and S. versicolor 

 sp. nov., smaller than either and more strongly suffused with green. 



Fweviings: with the basal line, limiting the basal area, nearer the base, and 

 the outer line nearer the hindmargin ; this latter shaped as in versicolm; not incurved 

 as in emunctaria, the median shade strongly marked, biangulate beyond the ocelloid 

 cell-spot ; the dark shade between outer and subniarginal line as decideil as in 

 emunctaria, but not so regular, and more sharply dentate, joined to hindmargin by 

 a dark cloud between veins 5 and fi. above which the apex of the wing is paler. 



Hindwi'iujs : darker than in emunctaria, more speckled with grey, Iml nol 

 brown as in versicolor, with the three lines well marked as in this latter species ; 

 the cell-spot small and obscure. 



Underside whitish oehreous, speckled with fuscous; forewings with a broadish 

 black subniarginal band, slightly angled lieyond cell (in emunctaria it is always 

 straight throughout): hindwings with the band almost obsolete. Head, thorax, and 

 abdomen greenish cinereous. 



Expanse of wings: 39 mm. 



A pair from the Escarpment. British Kast AiVica. the r? ipiite perfect, dated 

 September— October 1900, the ? March — April lilOl (Doherty). 



8(i. Scotopterix versicolor s|i. nov. and ah. albimedia nov. and figurata nov. 



Foreudvijs : oehreous, sufl'used with dull red-brown and moss-green, and thickly 

 striated and speckled with fuscous and olive, the suffusion and speckling varying 

 greatly in intensity; the two lines black, sometimes indistinct, lunulate-dentate, at 

 others velvety black and broad ; first from one-third of costa to one-third of inner 

 margin, slightly angled outwards below subcostal, and always prominently but bluntly
