PIERIN.E. 43 



the form and position of the small dusky costal stripe in the former 

 reminds one of the similar marking in the $ Pcqnlio Mcriones, Feld., 

 of Madagascar, and indicates (with the well-developed but not very 

 broad hind-marginal borders) the initial stage of the extraordinarily 

 developed dark markings which characterise the typical fonn. I have 

 suggested (Proc. Ent. Soc. Lonih, 1881, p. viii.) that the $ Saha may 

 be modified in mimicry of a common and evidently protected slow- 

 flying diurnal moth, Nyctemera ajpicalis, Walker, which has a very wide 

 African range, and possesses a near ally in ]\Iadagascar. 



As I have noted {loc. cit., p. vii.), Colonel Bowker captured the paired 

 sexes near the XJmgeni, Natal, in January 1881, and I believe that this is the 

 only instance of such capture recorded in the case of tliis species. The two 

 specimens in question are ligured in Trails. Ent. Soc. Land., pi. ix. (188 1), the 

 $ being an individual with the marginal markings rather more pronounced 

 than usual, and the ? one of strongly developed black markings throughout. 



The late Colonel Tower first made this species known to me as a South- 

 African native, having taken the $ at St. Lucia Bay. In 1872 the late Mr. 

 E. C. Buxton met with two of each sex on the Natal Coast (D'Urban and 

 Yerulam) during October. 



The butterfly appears to be far from common in Natal. I did not meet 

 with it during my visit in 1867, and Colonel Bowker has sent only five 

 examples. From Delagoa Bay, Mrs. Monteiro has sent several of both sexes, 

 including two of the $ Yar. Flavida. A single $ of this variety occurred in 

 a collection made in Mashunaland, near the Zambesi, in 1S82, by Mr. F. C. 

 Selous. 



The distribution of Saha in the Ethiopian Eegion is very wide, embracing 

 apparently a very large portion of the South-Tropical tracts and much of the 

 North-Tropical coast on the Western side. In Madagascar it would appear to 

 be rather numerous, being of frequent occurrence in collections sent from 

 thence. I have not found any notice of the particular haunts or habits of the 

 species. Colonel Bowker's Natalian specimens were taken in the month of 

 January.

^ In marking, the nearest ally of the ? Saba is the 9 of the Malayan and Sumatran 

 Ci/nis, Hewits., figured by Mr. Distant {Rhop. Malay., pi. xxvi. f. 6) as Udaina Cynis. In 

 this ? the white is even more reduced in the fore-wings, the subapical spots being wanting, 

 and the luwer part of the discal band much narrower ; the black is, however, represented 

 by dull fuscous-brown, which is ill-defined in the hind-wings. The i Cynis has a broad 

 costal, apical, and hind-marginal black border in the fore-wings.
