typical form of the spo'cie;;, wliile other specimens are often imlistinguishable from 

 the latter, and one is as justilied in treating the rather i)revailing aberrant speci- 

 mens as mere individual aberrations, which are, however, local in this case, as one 

 may consider them to belong to a local race which is still very inconstant, and 

 till produces numerous atavistic specimens. I take the last point of \'iew, and 

 accordingly have to enumerate the Chinese P. sarpedon as 



(/)) : P. sarpedon semifasciatus Honr. [ ^ , ? ].

 Papilio sarpedon, Aitken & David.s., Jonrn. Bombaij N. II. Soc. p. 304. n. 08 (1890) (Karwar ; 



larvae from July till October). 



^Median band of the wings mostly much narrower than in P. sarpedon, the veins 

 crossing the band nearly all black; hindwings witli the upi)er median vein produced 

 into a rather prominent tooth. 



The first spot of the median band is sometimes ab.sent, as Felder already said in 

 tlie diagnosis of teredon ; this alierration is described by Swinhoe as a distinct species ; 

 it occurs together with teredon in Ceylon and Southern India. 



(a-) : ab. tliermodttsa (Swinhoe).

(./) : P. sarpedon parsedon Westw. [J]. 



Papilio panedon Westwood, Tr. Ent. Soc. Load. p. 99. t. .'.. f. 1. 2 (1872) (patria?). 



Small form ; band of the wings as broad as in P. sarpedon choredon Feld. ; 

 hindwings with longer tooth than in P. sarpedon teredon F'eld. 



IJah. Timor, Dili (W. Doherty, .May 1892) (1 6) ; Wetter (id., May 1892) (1 i) ; 

 Adonara (id., November 1891) (1 i). 



I believe to be right in identifying the form from the lesser Sunda Islands with 

 Westwood's species. The type-specimen (in coll. of Messrs. Godman & Salvin) was 

 jjrobalilv killed soon after the emergence from the pupa, hence the white colour of the 

 median band ; I have two bred specimens of chm-edon which exhibit the same colour.
