46 SOUTII-AFRICAX BUTTERFLIES. 



February 1867 ; it was flying pretty actively in a wood at the Uuililanga, and 

 was netted by the late Mr. M. J. M'Ken, with whom I was on a collecting 

 excursion. Mr. W. Morant lent me in 1869, for description, a (J captured 

 near Pinetown, and Colonel Bowkcr sent a perfect specimen of the same sex 

 taken by him in that locality in June 1884, as well as a pair which he took 

 nearer D'Urban in 1881. Single examples have also reached me from Maritz- 

 burg and St. Lucia Bay, as well as three forwarded from Delagoa Bay by Mrs. 

 Monteiro. Moschler (Verk. K.K. Zool.-Bot. Gesellscli. Wien, 1883, p. 10) 

 notes the receipt of a $ from Baziya, east of the Bashee River in Katfraria 

 Proper ; and this is the southern limit of the range of the insect, as far as I 

 can discover. It is not improbable that Thysa is less rare than it appears to 

 be, as it might very often be passed over by collectors as the common M. 

 Agathina.^

1 No fewer than eleven specimens have been sent to me by Mr. A. D. Millar, who took 

 them in the vicinity of D'Urban, Natal. From the dates of capture kindly furnished by 

 Mr. Millar, I find that nine of these (six 6 s, three ? s) were taken in August and Sep- 

 tember 18S7 ; they are all smaller than usual, and have the hind-marginal black markings 

 decidedly reduced. The remaining two are a pair taken in cojyuld on the 29th January 

 1888 ; they are of large size, and both (but more especially the ? ) have the hind-marginal 

 markings strongly developed. The ? , indeed, has these markings (more particularly in 

 the hind-wings) larger and more extended inwardly than in any other example that I have 

 seen ; her fore-wings are almost pure white on the disc, but the reddish basal suffusion is 

 densely clouded with grey, and there is a separate patch of grey scales near posterior angle. 



I suspect that the larger and more strongly marked specimens represent what is the 

 summer or wet-season brood. The ? that I took in February was also very large, and had 

 the dark markings much developed.
