been very sceptical as to the identity of Pieris Saba, Fab. (the female form, 
which is more black than white) with Pieris orbona, Boisd. (the male 
form, which is almost entirely white). Mr. Trimen further expressed his 
opinion that the black and white female of this butterfly was probably 
modified in mimicry of a common and evidently protected diurnal moth, 
Nyctemera apicalis, W\k., which frequents the same localities. 
The sexes of Diadema mima, Trimen, taken paired at D’Urban on 
February 11th last. ‘This butterfly is an accurate mimic of Amauris 
Echeria, Stoll., copying the variety with white-spotted fore wings, which is 
common in Natal. The pair exhibited presented no particular disparity, 
except in the much smaller size of the male; but Mr. Trimen mentioned 
that he had recorded (Trans. Ent. Soc., 1873, p. 107, note) the capture in 
Natal, by Mr. H. C. Harford, of a male D. mima in copula with a female 
D. Anthedon, Dbld., of the form named marginalis by Mr. Butler. He 
also then called attention to the unstable characters of the African group of 
Diadema (Euralia of Doubleday), to which these differing but closely allied 
forms belong, and to the extraordinary accuracy with which they mimicked 
the various species of Amauris, even to the variations presented by the 
latter. 
The larval cases, pupe, and imagos of a Tinea (apparently T. gigantella, 
Stainton), found inhabiting the hoof of a horse. Col. Bowker writes that 
he sent to England a hoof of the troop-horse killed with the Prince Imperial 
in Zululand in June, 1879, to have it mounted as an inkstand. Since the 
return of the inkstand he had been obliged to take it to pieces to get rid of 
the moths, which were still emerging as late as February last. Tinea 
gigantella (originally described by Mr. Stainton from specimens brought by 
Mr. ‘Trimen from South Africa in 1859) is considered by the founder of the 
species as synonymous with Zeller’s Scardia vastella, whose larva is noted 
as feeding on the horns of antelopes. The closely allied 7. orientalis has 
also been recorded by Mr. Stainton (Ent. Mo. Mag., xv., 133) as having, in 
all probability, been bred from buffalo-horns brought from Singapore. 
Mr. Stainton remarked that it would be interesting to know whether 
these Tinee@ fed on the horns or hoofs of living animals. He believed Lord 
Walsingham had prosecuted enquiries on the subject with at present a 
negative result. 
The Secretary read a letter received from the Colonial Office relative to 
the appearance of Phyllowera vastatrix on the vines of Victoria, also a 
letter addressed to the Colonial Office, from the Royal Gardens. Kew, by 
Mr. W.'T. Thiselton Dyer, on the subject, and laid the minutes of evidence 
taken by a select committee of the Legislative Assembly, received as an 
enclosure, on the table. 
The President stated that this communication had been considered by 
the Council of the Society, and they had resolved that Messrs. Trimen,
