the form and position o£ the small dusky costal stripe in the former 
reminds one of the similar marking in the $ Papilio 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 form. I have 
suggested {Proc. Ent. Soc. Zoncl, 1881, p. viii.) that the $ Saha may 
be modified in mimicry of a common and evidently protected slow- 
flying diurnal moth, Nydcmcra apicalis, Walker, which has a very wide 
African range, and possesses a near ally in Madagascar.-^ 
As I have noted {loc. cit., p. vii.), Colonel Bowker captured the paired 
sexes near the TJmgeni, Natal, in January 1881, and I believe that this is the 
only instance of such capture recorded in the case of this species. The two 
specimens in question are figured in Timis. Ent. Soc. Lojid., 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. 
£. C. Buxton met with two of each sex on the Natal Coast (D'Urban and 
Verulam) 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 1882, by Mr. F. C. 
Selous. 
The distribution of Saha in the Ethiopian Region 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 ? Saha is the ? of the Malayan and Snmatran 
Cynis, Hewits., figured by Mr. Distant {Rltop. Malay., pi. xxvi. f. 6) as Udaina Cynis. In 
this 9 the white is even more reduced in the fore-wings, the subapical spots being wanting, 
and the lower 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.
