3895.] L. de Niceville & Dr. L. Martin— Butterflies of Sumatra. 519 
November and January. The Hon. Walter Rothschild in Novitates 
Zoologies, 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 him 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. hewitsoni should stand as a full species, with P. perses 
as a local race. 
589. Papilio ( Menamopsis ) petra, 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. petra, 
de Niceville. He may be correct in 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, Zinkeu-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. Jcerosa, 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. butleri ; they are all obviously very 
nearly allied to that species and to one another. P. butleri was des¬ 
cribed from Malacca, and is ’ recorded by Distant from I rovince
