sppciniPiis havp a subdiscal series of spots on the hindwiiigs beneatli, consisting of 

 rather disjiersed lilue scales, which appear sometimes also in P. memiion. The 

 amount of bluish grey scales on the upperside varies considerably; specimens with 

 only a few bluish grey scales above are — 



(p) : ab. depelchini Robbe. 



(J. Piqiilio (iii(lrngii,.< var. ilipih-hmi Robbe, Ann. Soc. Enl. Bili/. p. 125. n. 12 (1802) (Kurseong, 

 Sikkim). 



I have a mnlf and a ferivde of this aberration from Sikkim which are very peculiar 

 in the almost total absence of bluish grey scales from the upperside of the wings and 

 in tiie greenish metallic gloss of the hindwings; the hindwings of both specimens 

 are produced into a tooth at the end of the ujjper median nervule. as it is mostly the 

 case in P. inemnon pryeri Kothsch. 



Two other males, from Sikkim and the Khasia Hills, are \'ery remarkable in 

 pattern ; they remind one rather strikingly of the pattern of P. polymnestor Cram, 

 and Idmpsacus Boisd. I propo.se to name these specimens — 



(iiv') : (S-ab. primif/enius ab. nov. 

 Upperside: hindwings in the anal region with a series of four (Kliasia Hills 

 specimen, type) or two fSikkim specimen) black .spots, wholly encircled with almost 

 white .scaling; bluish grey streaks much whiter than in the usual form of the nude. 



Underside : hindwings with an anal and three submarginal complete grey rings, 

 the anal one and a grey subdiscal lunule between the two lower median nerxules 

 tinged with red at their basal sides : in the Khasia Hills specimen there is a second grey 

 lunule before the middle median nervule, and in each of the three anterior cellules 

 stands, close to the white marginal fringe, a grey spot, which is partly joined to a 

 submarginal indistinct lunule, so as to form an incomplete submarginal grey ring ; the 

 subdiscal series of blue spots is complete; in the Sikkim specimen these spots are 

 rather well defined. 



The specimens were obtained in Sikkim in May 1886 (Aloller leg.), and in the 

 Kl a^ia Hills in April 1889 (Kev. Hamilton leg.). 



In one male from Burma in my collection the forewings have a large red basal 

 mark, as in the female, and the hindwings, besides an anal red ring, a small and 

 indistinct submarginal sjjot of the same colour before the lower median vein on the 

 upperside. 



?. Dimor[ihic in shai)e of the hindwings; polymoriihic in pattern. Specimens 

 of the tailless form with the disc of the hindwings white are often indistinguishable 

 from the corresponding aberrations of P. memnon. The anal angle of the hindwings 

 is tinged with red or oehreous. 



(c') : ?-f. agenor I.,., I.e. Tailless, with the following principal colour 

 varieties : — 



(>r) : Typical coloration. Hindwings white, exclusive of basal half and 

 submarginal black spots. (l'"igures: Clerck, Icon. I. t. 1 .i ; Cramer, 

 I.e. t. 32). 



(o-) : White of hindwings occupying also part of cell. 

 {p-} : ?-ab. phoenix Distant, I.e. 

 White area reduced to five patches, the posterior ones of which are strongly 

 tinged with red, chiefly at their outer borders.
