Kanges from Persia to N.W. India, and thence through 

 Bombay southwards to the foot of the Nilghiri Hills. I have 

 seen no examples from the eastern side of India. I think 

 that Mr. Marshall is incorrect in his assertion that it appears 

 to range practically throughout India : our selected series of 

 seventy-four specimens does not include one example from 

 Eastern India. This makes it all the more probable that 

 Mr. Marshall's inconsistent action in regarding the Ceylonese 

 T. limbatus as a variety of T. etrida, whilst he regarded 

 T. danae as quite distinct from the company to which he 

 gave the name of T. eupompe, was an error. Just as T. danae 

 differs from T. dulcis, so does T. limbatus differ from T. etrida^ 

 whilst the latter has the additional advantage of being a 

 purely insular form. 



Of the varieties of T. etrida to which I gave distinctive 

 names, T. farrinus is the most heavily marked on the upper 

 surface, though T. pernotatus runs it very close ; T. purus is 

 a dwarf form of the species with rather more orange at apex 

 than in typical T. etrida. These are all wet-season or inter- 

 mediate forms. The dry-season phase is represented by 

 T. casimirus and the starved form of it which I described 

 under the name of T. bimbura.

Ceylon. 



The males of this species are always heavily bordered, and 

 sometimes so much so that the marginal spots are perfectly 

 confluent throughout; the species seems never to attain to 

 the size of the largest examples of T. etrida. The female on 

 the upper surface (like its male) resembles most nearly that 

 sex of T. etrida, var. farrinus ; but is more heavily bordered, 

 shows scarcely a trace of the spot on the interno-median 

 area of primaries, has brown instead of black markings on the 

 under surface of these wings, and the discal markings on the 

 secondaries very ill-defined. An example of this sex is in 

 the Hewitson collection.
