N0VITATE3 ZOOLOGICAE XXII. 1915. 89 



Bauksiau collection goes, Fabricius' treatment of them and the assignment to them 

 of the same locality, vague as it is, all go to suggest that the specimen oi phaedrus, 

 placed close to them in the Banksian collection and described by Fabricius under 

 the following number, really came from the same place, and are S and ? of the 

 same species. Fabricius quotes Drtiry's figure of thctis as being the same insect. 

 He quotes it, by the way, as theti/s, a circumstance tliat accounts for the confused 

 variation in the spelling of the name, which is common ; Drury, however, says 

 thetis. 



The ? ? of thetis and phaedrus are so much alike that neither de Niceville nor 

 Bingham attempt to discriminate between them ; they both, in fact, accept the two 

 species in both sexes to be identical. They are, however, quite distinct ; but, 

 omitting this fact for the moment, I fully accept Bingham's conclusion as to 

 aesopus, that it " falls as a synonym of G. thetis* as acknowledged by Fabricius 

 himself. The type, a ? , is in the Banksian collection now in the British Museum, 

 and is undoubtedly a ? of ordinary C. thetis, Drury." 



I have examined a good many specimens claiming to be aesopus, and nearly all 

 of these prove to be bulis, but I have two specimens whose S appendages agree 

 precisely with those of C. sperthis {q.i\). 



arcuata Moore, Proc. ZooL Sue. Land. 1883. p. 52.3. PI. xlviii. fig. 3 (Malabar). 



The iignre and description agree with a specimen labelled " Curetis arcuata 

 Moore," " Malabar," from the Moore collection, and apparently in Moore's writing. 

 This specimen is phaedrus. 



Unauthenticated specimens sent me as arcuata from Nias are forms of bulis. 



C. phaedrus seems to have a comparatively restricted range, the extreme South 

 of India, Balai, "Malabar," Ceylon, Bombay, Barrackpore. So far as I know, 

 phaedrus is the only Curetis occurring in Ceylon ; but it is surely highly probable 

 that thetis occurs there also. 



What any particular records mean is of course donbtfnl, so long as phaedrus 

 and thetis are more or less confounded. On the other hand, the thetis of Moore's 

 Lepidoptera of Ceylon is no doubt phaedrus. 



3. Curetis celebensis Felder. 



Figs. 23 and 24. Male, upper- and underside. 



Appendages. Fig. 68. 



celebensis Felder, Reise Novara, Lep. p. 220. Tab. xxviii. fig. 14, 1.5 (1865). 



The figures are of the ? upper- and undersides, and agree exactly with the 

 specimens. The reduction of the rusty marks on upperside to somewhat linear 

 marks on the forewing, and tendency to divide that on hindwing into two portions, 

 is characteristic. 



There seems to be no figure of the male, and this sex does not appear to 

 have been known to Felder. There are, however, in the Tring collection several 

 males, collected by Doherty in South Celebes in August and September 1891. 



The South Celebes specimens in the Tring Museum belonging to this species 

 and to C. tagalica form a remarkable group. The two species are so much alike 

 that in both sexes the distinction is at first sight diflftcult. Both seem to have 

 been taken by Doherty at the same time and place. In the males in both species
