wards as far as Beluchistan, both dry- and wet-season forms 
flying together; the form with yellow under surface, which 
is the wet-season representative, is 7. pued/aris, and that with 
the apex of primaries and the whole of the secondaries sandy 
buff on the under surface, which is the dry-season type, is 
T. ochreipennis (= T. rorus). We have both forms captured 
on the 29th of June and in November. It is therefore 
evident that, as in some other dry localities, the seasonal 
forms in this species represent mere varieties which appear 
simultaneously. Among Hewitson’s examples of 7. phisadia 
is a male of the wet-season form labelled “ Aden”; but this 
must surely be an error, unless the white females referred to 
T. phisadia, and obtained at my request by Col. Yerbury, 
flying with the latter species, actually belong to the dry-season 
variety of 7. puellaris. This, however, is extremely im- 
probable *. 
6. Teracolus vestalis.

Occurs from Kutch through Karachi and Beluchistan to 
the coast of Persia. The varieties representative of seasonal 
forms in this species fly together in April, May, and June ; 
but we have only received the dry-season types as obtained 
in November and December. ‘The wet-season type is typical 
T. vestalis (= 7’. dubius) ; the dry and intermediate types are 
represented by TZ. tntermissus, of which 7. peelus is only a 
yellow female form, Swinhoe’s supposed male being merely a 
small example. 
7. Teracolus castalis. 
Idmais castalis, Staudinger, Exot. Schmett. p. 43, pl. xxiii. (1884). 
Originally described from an imperfect example obtained 
at Taita, EK. Africa; it has subsequently been received from 
Mombasa and from Somaliland. In the Museum there is 
one male from Mombasa of the typical wet-season form. 
T. castalis is the African representative of 7. vestalis, from 
which the longer costa of the primaries, the broader black 
apical and costal borders of these wings, and the distinctly 
spotted border of the secondaries readily distinguish it. 
* Hewitson’s utter disregard of the importance of correct habitats is 
evidenced by the fact that fully half his specimeus bear no indication of 
locality.
