be nearer to the Javan H. belia than to the whiter M. linteata, Butler, 

 from the Malay Peninsula, but at best the latter is but k 'a local race of 

 the former. For many years there existed a single specimen in Dr. 

 Martin's collection without locality label, and he nearly despaired of get- 

 ting it again, when in May, 1894, he obtained all at once in one spot five 

 specimens from Bandar Quala in Serdang, where no specimen of 

 H. lynceus, Drury, is ever found, as Mr. Puttfarcken, a very enthusiastic 

 collector of that place, has noted. 



3. Ideopsis {Gamana) daos, Boisduval. 



Snellen as Hestia daos. Hagen as I. daos, Horsfield and Moore 

 [sic]. Butler. Staudinger. Distant. Mr. W. F. Kirby, in "Allen's 

 Naturalist's Library. Lepidoptera," vol. i, p. 15 (1894), suggests that 

 the form of this species occurring in Sumatra may be distinct from the 

 typical Bornean form. I possess specimens from both islands, and 

 find that they agree almost exactly. Dr. Staudinger refers to a darker 

 form of the species occurring in Sumatra and Nias. The former is 

 normal ; the latter is the Qamana costalis of Moore, and is a distinct 

 species. In Sumatra I. daos is found not higher than Bekantschan. It 

 is mimicked by a very beautiful day-flying Moth, probably of the genus 

 Isbarta, Walker (? /. glauca, Walker, from Sumatra), family Zygsenidse. 

 On " The Crag " at Penang, 2,000 feet, J. daos is very common. 



4. Danais (Badena) vulgaris, Butler. 



Grose Smith. A common species of the plains, the female much 

 rarer than the male. It occurs all the year round, but if there should 

 be a break in the regular rainfall, as there is sometimes in February 

 and March, then only worn specimens are on the wing, shewing that 

 damp weather is necessary for the disclosure of imagines; otherwise 

 generation follows generation regularly throughout the year. 



5. *Danais (Badena) similis, Linnaeus. 



Grose Smith. Snellen. Hagen. Mr. Henley Grose Smith is the 

 only writer who gives both B. vulgaris, Butler, and B. similis from 

 Sumatra. Mr. Moore restricts B. similis to Hongkong and Formosa. 

 I greatly doubt its occurrence in Sumatra. 



6. *Danais {Badena) juventa, Cramer. 



Moore. Semper from West Sumatra. As it is found in Singapore 

 {Moore), Banka, Java, Labuan, Lombok and Billiton, it is possible that it 

 may also occur in Sumatra in the south and west. Banka and Java 

 are only separated from Sumatra by very narrow straits.
