Haragama, Ceylon, 13 February, 1908. A ? Ncpheronia 

 ceylonica, Feld., oa a Lantana tiower, was taken for 

 Parantica aglca. 



Durban, S. Africa, August, 1905. Acrmi eoicedon, Linn., a 

 somewhat feeble insect with slow flight, was, in spite 

 of its small size, twice momentarily believed to be 



D. chrj/sipjjus, which was seen in the same spots on 

 the same davs. On the other hand, a small 9. D. 

 chrysipims was actually mistaken for A. encedon* 



Durban, August, 1905. " Of Belenois thysa, Hopff., we 

 took two ^ ; when on the wing they were very like 

 the $ of Mylothris ayathina, Cram., in flight and 

 general aspect. Indeed as seen in the net the Bde- 

 nois so closely mimics the MyJothris that one of us, 

 though specially on the look out, was completely 

 deceived, and this even when the two insects were 

 taken the same morning." f 



Durban, August, 1908. "... the curious Geometer 

 Cartaletds libyssa, Hopff., of which several were seen, 

 but only one taken. It flies rather high, with feeble 

 fluttering action, and when on the wing somewhat 

 recalls Limiias chrysippus." % 



Kandy, March, 1904. " Of the tail-less Fcqnlio lanJcesimra, 

 Moore, f. dissiniilis, Linn, (the pale form), I took 

 three, but probably saw more since it so very closely 

 mimics Tirumala livmiace, or a large Parantica cey- 

 lonica {aglca), as easily to pass for one of those 

 insects; it is indeed most easily distinguished from 

 them by its habit of fluttering while feeding upon a 

 flower." § 



Near Peradeniya, Ceylon, 29 January, 1908. I was with 

 that experienced and keen-eyed entomologist, Mr. 



E. E. Green, when he netted a P. lankesivara, f. dis- 

 similis, under the impression that he was catciiing 

 Tirumala se2)tentrionis, Butl. 



Kandy, 2 March, 1908. I myself took a $ P. dissimilis 

 which I imagined to be Tirumala scptentrionis as it 

 flew past. 



Haragama, Ceylon, 18 February, 1908. Took a $ P. lan- 

 Jceswara, f. clT/tia, Linn, (the dark form), believing it to
