148 Col. C Swiiilioc on 



IMakassar, Celebes, and females from Palembang, Sumatra, 

 and from Nikko, Japan; the last, collected by Mr. Sanson, 

 in no way differs from the other Island examples. Piepers 

 appears to have bred tliese in Java : I had put them together 

 in my collection long before I saw Snellen's paper ; by some 

 curious mistake, though he has figured correctly Walker's 

 type of sordida, he has printed a Avrong name and a wrong 

 reference both of the text of Cat. Het. Mus. Oxon. and of 

 the number of the figure on the plate. 



16. Cyclosia distinctu. 



Gynautocera distincta {2), Gii6r. Voy. Deless. p. 85, pi. xxiv. fig. 3 



(1843). 

 Eterusin drafavaja {6), Moore, Cat. Lep. E. I. C. ii. p. 321, pi. viii. a, 



tig. 3 (1859). 

 Etenisia osscata ($), Walker, xxxi. 120 (1864). 



Java, Borneo, Sumatra, Mergui. 



From all the above localities in the B. M. ; in my collec- 

 tion from Jelebu, Singapore, Sarawak, and Sandakan ; they 

 are undoubtedly sexes of the same species. Moore's type 

 from Java is in the B. M., Walker^s type from Sumatra in 

 Mus. Oxon. Guerin's locality Assam is undoubtedly wrong ; 

 at all events, it has never since been recorded from India 

 proper. There is an example, however, in Mus. Oxon., taken 

 by Mouhot in Cambodia, Siara. 



17. Isbarla pieridoides. 



Epyryis pieridoides, Herr.-SchafF. Ausser. Schmett. i. p. 5 (1853). 



Java, Borneo, Sumatra, Nias. 



The type came from Java. Only females have heretofore 

 been known ; the male is glaucous blue, about half the size of 

 the female ; it somewhat resembles Isbarta glauca. Walker, 

 has the same kind of yellow band on the abdominal margin 

 of the hind wings below, but otherwise the markings above 

 and below are identical with those of the other sex except 

 for some black suffusion on the outer third of the fore wings 

 above and white submarginal spots : it has heretofore been 

 mixed up with glauca in collections ; the female of that form 

 is not yet known. There is a form oi pieridoides in Sumatra 

 and another in the island of Nias, in which the females are 

 very similar, but the males have the thick black vein- 

 markings on the hind wings very obscure and more white 

 spots on the fore wings. There are in the B. M. and in my 

 own collection cxam{)les of both sexes of all three forms.
