SATYRINJS. 61 



very small larvae whicli had emerged on November 4th from eggs laid by a female of 

 Y. philomela [Baldus] on October 29th. On December IGth, one larva changed to a 

 pupa, which disclosed a male imago on January 5th; on December 18tli, a larva 

 changed, a female imago emerging on January 10th; on December 2-ith, a larva 

 changed to a pupa, a female emerging on January 16th ; and on December 28th, two 

 larvae changed to pup«, a female emerging on January 19th from the one, and a male 

 on January 20th from the other. Two larv89 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. Marshallii. 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." 



Variability 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. Examples 

 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. 



Distribution. — Specimens of T. 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 Eastern India ; of the wet-season brood from 

 Chittagong, taken in September ; Mandalay ; Bhamo, taken in November ; Karen 

 HiUs ; 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. P. Hampson (J. A. S. 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 E. 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 Tihn Yaw, in December ; and of the dry- 

 season brood from Toungoo, in March, from Beeling in March and April, from
