^ Dull fuscous-yello'W-ochreoKS, with Hack spots, and dull UacJcish 

 borders. Forc-iving : a large, more or less defined, elongate spot at 

 end of, and running into, cell ; beyond it, from costa, a row of con- 

 fluent spots, angulated inwardly on third median nervule and extending 

 to middle of submedian nervure (the whole of the row below third 

 median is often wanting or very faintly marked) ; costa rather narrowly 

 bordered with greyish; hind-marginal blackish border broad, nearly 

 even throughout ; a smooth greyish space covers median 7iervulcs at their 

 origin. Kind-wing : the broad blackish border leaves only an inner- 

 marginal and discal ochreous space, not extending above discoidal 

 nervule ; crossing ochreous nearly to submedian nervure an ill-defined 

 macular stripe. Under side. — Hind-wing and borders of fore-wing 

 hoary-grey, the former crossed hy two roivs of faint-hrownish confluent 

 spots. Forc-iving : iiale ycllow-ochrcous ; spots as above, but smaller and 

 more distinct, — that closing cell divided into two, of which the inner 

 is very much the smaller ; below the inner of these two, outside cell, 

 a small round spot ; hind-marginal border faint-f ascous towards anal 

 angle, sometimes marked interiorly by a row of very indistinct, small, 

 dark spots. Hind-ioing : markings variable and often very indistinct ; 

 macular row before middle very irregular and sometimes very much 

 broken up, — a portion of it always marks end of cell, where it is often 

 confluent with the more regular, broader, and better-defined discal 

 row ; two or three indistinct brownish spots near base. Cilia white 

 or whitish, interrupted with dull-blackish on nervules. 



^ Similar, but ochreous much clearer and yellower, so that the black 

 spots are more conspicuous ; borders brownish. Fore-iving : spot at end 

 of cell often divided, sometimes confluent with discal row on third 

 median ; no grey space at origin of median nervules. Hind-wing : 

 a streak closing cell sometimes visible. Under side. — As in $, but 

 markings of hind-ioing sometimes better marked. 



This species varies mncli in both sexes, both as~regards the extent and 

 clearness of the ochreous-yelloAV of the upper side, and the definition, size, and 

 shape of the spots on the under side of the hind-wing. Near Cape Town and 

 at Stellenbosch, the dusky typical form (described by Linnseus and the $ 

 floured by Cramer) prevails, and in these the discal black spots are almost 

 always strongly developed on the upper side. At Triangle Station (elevation
