SATYRIN ZL. 61 
very small larve which had emerged on November 4th from eggs laid by a female of 
Y. philomela [Baldus] on October 29th. On December 16th, one larva changed to a 
pupa, which disclosed a male imago on January 5th; on December 18th, a larva 
changed, a female imago emerging on January 10th; on December 24th, a larva 
changed to a pupa, a female emerging on January 16th; and on December 28th, two 
larvee changed to pupx, a female emerging on January 19th from the one, and a male 
on January 20th from the other. Two larve died, having shrivelled up in the act of 
turning, possibly in consequence of the atmosphere of the glass-jar in which I bred 
them not being sufficiently moist, for in nature these animals must get heavily 
drenched with dew every night. All these butterflies bred from eggs laid by Y. philo- 
mela proved to be true Y. Marshall. I may add that Captain Sage, who kept a 
careful register of his captures from day to day, first observed ‘ wild’ specimens of 
Y. Marshallii on November 18th, having for months before caught Y. philomela 
only.” 
VanriaBILITy IN Size.—In this widely-distributed species the size of the specimens 
vary considerably. Specimens, under examination, from Western India (Kattywar, 
Bombay, Mahableshwar) are the smallest—and also the palest in tone of colour on 
both the upper and undersides, in both the wet and dry-season broods. Hxamples 
from South India (Nilgiris) are variable in size, some being small, others large, and 
of darker tint throughout the upper and underside. Those from the Plains of Lower 
Bengal are large and prominently marked in the wet-season brood, but are paler in 
the dry-season brood. Chittagong and Upper and Lower Burmese specimens are also 
of the larger size. 
Distripution.—Specimens of 7’. Baldus, as here described, have been examined 
and verified from the following localities :—In our own collection are examples of the 
wet and dry-season broods from Kattywar, Bombay, Poona, and Mahableshwar, in 
Western India; from the Wynaad, Nilgiris, and Travancore, in South India; from 
Calcutta and the Khasia Hills, in Hastern India; of the wet-season brood from 
Chittagong, taken in September; Mandalay; Bhamo, taken in November; Karen 
Hills; Toungoo, in Tenasserim, and of both the wet and dry-season brood, taken in 
the Mergui Archipelago, by Dr. J. Anderson, from December to March. 
Mr. G. F. Hampson (J. A. §. Beng. 1888, 349) obtained it in the Nilgiris, the 
wet-season brood in May and August, and the dry-season brood from December to 
April; being very common on the lower slopes of the Hills. 
In Captain EH. Y. Watson’s collection are specimens of the wet-season brood 
from Mysore, taken in November, from the Nilgiris, taken in August, and of the 
dry-season brood, in December and January; the wet-season brood from Rangoon, 
in August; Toungoo, in November; Poungadaw, near Thyetmyo, in October and 
November; Pauk Yaw, in November, and Tilin Yaw, in December; and of the dry- 
season brood from Toungoo, in March, from Beeling in March and April, from
