collected at the following extremely interesting localities :— 
British Baluchistan, Quetta (6,000 ft., 1902-3), 60 specimens ; 
Pishin (5,000 ft., Apr. 1902), 2 specimens; Kashmir (8,000-—- 
9,000 ft., June, Igo ; 5,000-6,000 ft., May 1901; 5,000 ft., Apr. 
19OI ; 4,000 ft., June, 1901), 7 specimens ; Bombay Presidency, 
Disa (1897, 1901), Bombay (1904), 19 specimens. 
Thirty-nine butterflies, of which 19 have been catalogued, 
from various localities in Mauritius (1905-7), were presented 
by the captor, Colonel N. Manders, F.E.S. The data are full 
and precise, and the specimens are a most interesting addi- 
tion to the island forms in the University Collections. Colonel 
Manders also presented a valuable series of 255 specimens of 
the Satyrine butterfly J/elanitis leda, taken by him between 
March 10 and Dec. 31, 1905, at Curepipe, Mauritius (about 
1800 ft.). All the specimens are carefully dated. Setting 
was a matter of great difficulty, from the effects of formaline 
which had been added to destroy mould; but Mr. A. Cant, 
F.E.S., to whom the butterflies were entrusted, has succeeded 
in displaying them admirably, in spite of this obstacle. This 
species has for many years been known to exhibit seasonal 
changes in a marked degree, the wet-season individuals 
possessing well-developed “eye-spots” on the under sides of 
the wings. In specimens of the dry season the apex of the 
fore-wing is produced and bent, while the under-surface, 
without eye-spots, beautifully resembles a dead leaf, the ap- 
pearance of black, leaf-attacking fungi being often represented 
by the so-called “ink-marks.” Although so well known, the 
nature and mode of incidence of the physiological stimulus 
which causes the change is still imperfectly understood, and 
the problem, apparently so simple, is of great difficulty. ‘This 
fine series, all set to show the under-surface of the wings, and 
arranged in order of date, side by side with the rainfall of the 
locality for the year 1905, cannot fail to throw much light 
upon it. 
Seven butterflies from Bourbon (Réunion), captured in 
April, 1907, were also presented by the same donor. Very few 
examples from this island exist in the Hope Department. 
Forty-nine butterflies and 13 moths, captured by Colonel
