266 THE ZOOLOGIST. 
A communication was read from Mr. Francis Day, containing remarks 
on the range of Apogon Elliotti.—P. L. Sctarer, Secretary. 
EntomonocicaL Socirty or Lonpon. 
May 4, 1881.—H. T. Stainton, Esq., F.R.S., &c., President, in the 
chair. 
Mr. R. W. Fereday (Christchurch, Canterbury, New Zealand), hitherto 
a Corresponding Member, and Mr. Charles Foran (Marshfield House, East- 
bourne, Sussex), were balloted for and elected Ordinary Members of the 
Society. Mr. James Edwards (Bracondale, Norwich), was elected an Annual 
Subscriber, 
Mr. Roland Trimen exhibited and made remarks on the following 
Lepidoptera, all of which had been taken in Natal by Col. J. H. Bowker :— 
The sexes of Pieris Saba, Fab., captured in copula near the Umgeni in 
January last. Mr. Trimen remarked that, as long ago as 1837, Boisduval 
had united the strikingly dissimilar sexes of this Pierid; but he was not 
aware that there was any record of positive evidence in support of that 
lepidopterist’s opinion. He was especially pleased that Col. Bowker should 
have been the captor of this pair; as in spite of his intimate acquaintance 
with the extraordinary sexual disparity prevailing among butterflies, he had 
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 farther 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, Wlk., 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 larval cases, pup, and imagos of a Tinea (apparently T. gigantella, 
Stainton), found inhabiting the hoof ofa 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.
