hinder angle stands sometimes a feeble white mark. The series of submarginal spots 

 to the underside of the hindwings seems to be complete in all specimens, though the 

 three anterior ones are occasionally much reduced iu size ; above, the cell of the hind- 

 wings has in two of my individuals a white spot at the apex. 



S. The patch within the cell of the forewings is inconstant in size; the spot 

 before the upper median nervule is liable to obliteration on tlic upper surface ; below, 

 the forewings have in one of my specimens two faint white submarginal spots, one 

 before, the other behind the second discoidal nerxnle. The white discal patches of 

 the hindwings are not quite constant in size.

i. Difl'ers from P. hecataeus Godm. & 8alv. in the spot before and that behind 

 the upper median nervule of the forewings being absent, in the broader white band 

 of the hindwings, and in the three anterior spots of the submarginal row of the 

 hindwings below being obliterated. 



The spot before the lower median nervule of the forewings is mostly indicated, 

 seldom entirely absent ; the band of the hindwings enters apparently always the apex 

 of the cell; in one specimen in my collection the three anterior submarginal spots 

 on the underside of the hindwings are present, but extremely small. 



As the third and fourth si)Ots (counted from behind) of the macular band of tlie 

 forewings are in some individuals of P. hecaUiena very much reduced ; as further 

 the band of the hindwings of P. hecataeus is inconstant in breadth ; and as the three 

 anterior submarginal spots of the hindwings beneath are sometimes indicated, it 

 is not improbable tliat in future intermediate specimens between the males of 

 P. l/ecataeus and prospero will turn up. 



? . I have before me three specimens from Kubiana (Xew Georgia), one collected 

 by Mr. Woodford and two olitained liy Capts. Webster and Cotton. The.se individuals 

 differ from jNIr. Grose Smith's type-specimen in the cellular patch of the forewings 

 lieing much larger, even larger than in P. hecataeus ; in the discal patches of both 

 wings being as large as in this latter species, not smaller; and in tlie marginal spots 

 of the hindwings being of mucli inferior size than in the type of pi-ospero. In 

 Woodford's example the submarginal spots of the hindwings are smaller than in 

 my other si)ecimens and in the tvpe. The marginal spots of the forewings of 

 P. prospero- ? (type) are merged together with the sulimarginal spots, exclusi\e 

 of the two spots before and behind the fifth subcostal nervule, which stand separate; 

 the two specimens collected by Capt. Webster exhibit the same character, but the 

 markings are smaller and the two anterior submarginal spots are wanting. In ^\'ood- 

 ford's specimen only two submarginal spots are developed above, and stand separate 

 from the marginal markings before and behind the second discoidal nervule ; below, 

 these two spots are confluent with the marginal ones, and there are two others before 

 them, standing separate, and three behind them being joined to the marginal spots. 



These /«»ia/es prove the same that I remarked about the raale, namely, that 

 the differences between P. hecataeus and prospero are scarcely of specific \alue, and 

 that P. prospero most probably will sink in future to the rank of a subspecies of 

 P. hecataeus Godm. & Salv.
