Ranges 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 J. etrida, whilst he regarded 
T. danae as quite distinct from the company to which he 
gave the name of J’. ewpompe, wasan error. Just as 7’. danae 
differs from 7’. 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 7. etr¢?da to which I gave distinctive 
names, 7’. farrinus is the most heavily marked on the upper 
surface, though 7. pernotatus runs it very close; 7. purus 1s 
a dwarf form of the species with rather more orange at apex 
than in typical J. etrida. These are all wet-season or inter- 
mediate forms. The dry-season phase is represented by 
T. casimarus and the starved form of it which I described 
under the name of 7’. bémbura.

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 7. etrida. The female on 
the upper surface (like its male) resembles most nearly that 
sex of 7. 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.
