of a blackish band ; the inner ftortion of the white band, wliicii is narrow and con- 

 tinuous with the portion near the apex of the cell, is often obliterated, and then 

 the band is interrupted before the upper median nervule. The position of the 

 jjosterior part of the white band is not always the same, the black marginal area 

 vaiying in breadth from 5 to 10 mm. at the lower median nervule. 



The hindwings are in some individuals more strongly toothed at the end of the 

 upper median veiu than in others ; there is no orange anal mark, as in P. jAolychus, 

 but often a small white anal spot. 



The markings of the underside are rather variable. Tiie forcwings exhibit often 

 small and ill-defiued submargiual white spots, which in some individuals form a kind 

 of submargiual band, 'i'iie submarginal spots of the hindwings vary in number, 

 shape, and colour. 



?. All my specimens have an orange anal spot on the u]iperside of the hind- 

 wings, which is sometimes larger than in P. ptobjchiis ; one example has also some 

 submarginal markings on the hindwings above. Below, the submarginal marks of 

 the hindwings are larger than in the laale, though they var^' in size, and are mostly 

 of an orange-yellow colour.

The figure which Cramer gives of his amphitrion difl'ers from (jambrisiua 

 especially in the pattern of the underside of the hindwings ; specimens agreeing with 

 Cramer's figui-e are unknown to science. Boisduval (I.e.) describes as amphitrimi an 

 insect which is, according to a typical specimen in Mr. Oberthiir's collection, a variety 

 of gambrisius and not amphitrion Cram. As Cramer refers to Seba (t. 8. f. 7. 8) and 

 gives as habitat " America," while Seba says " India occidentalis," and as, further, 

 the neuration of the figure is erroneous, I cannot help thinking that Cramer's figure 

 was, if taken from nature, drawn from a nintilatcd and painted-up specimen, perhaps 

 from the same sjx'cimen from which Seba's figures are taken; we know that Cramer 

 purchased a number of specimens of Seba's collection some forty years after Seba's 

 plates were drawn, and it is most jirobable that Cramer's figm-es of /'. amphitrion as 

 well SLS of Trollies hypolitus (i. 10. f. A. b) (see p. 200) were drawn up from Sel}a's (strongly 

 mutilated) individuals and restored with the help of Seba's figures. Anyhow, Cramer's 

 urnphitrion must for the present remain a doubtful species.
