Habitat. —Burma; Tenasserim ; Mergui Archipelago. 
Distribution. —Dr. J. Anderson obtained the type specimens in “ Mergui, in 
December ; Elphinstone Island in March, and Pataw Island, in January” {lx. p. 46). 
We possess a male of Wet form from Chittagong, and both sexes of the Dry form, 
and male of Extra Dry form from Mergui, and Bhamo, the latter taken by Dr. L. 
Eea in November, also a male of Dry form from Tounghoo, and Intermediate Dry 
male from Mergui and Bhamo ; also Extreme Dry male from Moulmeiu. Col. C. 
Swinhoe also has the latter form from Moolai, Tenasserim. 
Of our illustrations on Plate 574, fig. 2 is from a male Wet form from 
Chittagong; figs. 2a, b, from a male and female {co-types) of Dry form from Mergui; 
fig. 2c, a male of Intermediate Dry form; and fig. 2d, male of Extreme Dry form.
