Some confusion formerly existed as to the identity of this species, Boisduval's types, 

 —derived from Cochin China and Maniha,— forming a composite species,* of which the 

 PhiUppine insect has heen correctly separated hy G. R. Gray under the name of 0. nephereus. 

 I am indebted to my friend :\Ir. 0. Salvin for comparing my figure of the Perak female with 

 those in his own collection from X. India, and which he writes me do not disagree. Mr. Salviu 

 also writes, " Ornithoptcra rhadamanthus, var. Thomsoiiii, Bates, ex Siam, is based upon two 

 M.\LE specimens, which are hardly to be distinguished from O. rhadamanthus of N. India. The 

 wings are rather more elongate, but the difference is very slight and not constant." 



The male here figured (Tab. XXVII. a, fig. 5) is a very dwarfed form captured at Kwala 

 Lumpor by the Eev. L. C. Biggs ; the female (of which a woodcut is given) is a Perak specimen 

 kindly lent me for examination by Herr Georg Semper, of Altona. 



* Boisduval distiuctlY describes the female as havlns on the posterior win-s '■ la bordiire precedee d'un raiiR de taches 

 ovales," wliich a^i-ees with What is liere understood as his species, whilst he describes as his var. A, a femeUe ayaut la l».uluro 

 entieremeiit coutlueute avec les taches," which eutii-ely denotes the Phihppme species renamed by Or. a. Uraj.
