TERACOLUS. 19 



S. Persia.— Fao (/r. D. Cumming); Bushire, September [W. B. Cumming, Mus. 

 Brit). 



Mr. Guy Marshall ^\Tites : " This species is very nearly allied to the last, and is 

 perhaps doubtfully distinct. However, a few small distinctions appear to be constant : 

 thus, T. vestalis is larger, with the black border on upper side of secondaries propor- 

 tionately narrower ; on the underside ol' primaries the lowest of the three black 

 spots near posterior angle is small and well defined, but in T. puellaris it is large and 

 suffused along inner margin ; lastly, the females of T. vestalis have a macular discal 

 ray on the underside of secondaries, which appears to be absent in T. puellaris. With 

 regard to the synonymy, T. vestalis and T. dubius are the same ; T. infermisstis is the 

 dry-season form, and T. peeliis is merely the yellow female of it. This species has 

 much the same range as T. puellaris, but has been recorded a little farther west, 

 namely Fao, in the Persian Gulf" 



Dr. Butler's remarks on this species are as follows : " Occurs from Kutch through 

 Karachi and Beluchistan to the coast of Persia. The varieties representative of 

 seasonal forms in this speeies 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 ( = T. dubius) ; the dry and intermediate types are 

 represented by T. iiifermissus, of which T. peelus is only a yellow female form, 

 Swinhoe's supposed male being merely a small example."
