J895.] L. de Niceville & Dr. L. Martin — Butterflies of Sumatra. 519 



November and January. The Hon. Walter Rothschild in Novifates 

 Zoologicas, vol. ii, p. 362 (1895), records this species as P. slateri perses, 

 de Niceville, from North-Eastern Sumatra. Neither Dr. Martin or I 

 can agree with liim in sinking P. hewitsoni, Westwood, from Borneo, and 

 P. perses as sub-species of P. slateri, Hewitson, from N.-E. India, and 

 P. tavoyanus, Butler, from Burma. The two latter have extensive blue 

 markings on the upperside of the forewing, which the two former 

 entirely lack, and no intergrades between them have been found, so we 

 think that P. heivitsoni should stand as a full species, with P. perses 

 as a local race. 



589. Papilio (Menamopsis) petea, de Niceville. 



P. (Menamopsis) petra, de Niceville, Journ. A. S. B., vol. lxiii, pt. 2, p. 47, 

 n. 41, pi. iv, fig. 5, male (1894). 



Described from a single example from the Grayoe mountains taken 

 in January, 1893. No specimens have been obtained since. Rothschild 

 records this species as (c), P. slateri perses, de Niceville, (a 2 ), ab. pefra, 

 de Niceville. He may be correct iu assigning it to the position of an 

 aberration only, but as the type is unique, it may be kept distinct for the 

 present till further specimens are obtained and we know more about 

 it. Mr. Rothschild's note is as follows : — " This insect has been dis- 

 covered in the same district where P. perses, de Niceville, was obtained, 

 and it is most probably nothing but an atavistic example of the latter, 

 provided it has the same structural characters as P. slateri, Hewitson. 

 I have not had the opportunity to examine a specimen of this aberra- 

 tion." (Nov. Zool., vol. ii, p. 363 (1895). 



590. Papilio (Euploeopsis) butlert, Janson. 



Grose Smith as paradoxa. Wallace as paradoxa, local form b. 

 Hagen as paradoxa, var. zanoa. Dr. Wallace describes this species 

 from Sumatra without naming it as follows : — "Smaller than P. para- 

 doxa, Zinken-Sommer, from Java and Borneo ; intermediate in the 

 markings between the Java and Borneo forms ; interior row of elongate 

 marks on the upperside of the forewing light blue, not descending 

 to the outer angle." Mr. Butler has described and figured three 

 species of the paradoxa group from Sarawak in Borneo, viz., P. zanoa, 

 P. kerosa, and P. juda. Without having the actual types to compare 

 with Sumatran specimens, it is difficult to say if any of these supposed 

 distinct species are the same as P. hutleri ; they are all obviously very 

 nearly allied to that species and to one another. P. hutleri was des- 

 cribed from Malacca, and is recorded by Distant frdha Province
