212 Mr. Butler's Dcficri]itions of 



angulated subapical band from costal nervure to near first 

 median l)rancli and a bifid patch on inner margin white, 

 divided by black nervures ; secondaries with a broad 

 central white band ; nervures and internervular folds on 

 disc dusky ; base black spotted ; body as in preceding 

 species ; primaries below with apical area to external angle 

 greyish olivaceous, the nervures and folds black ; secondaries 

 with external area greyish olivaceous, interrupted by black 

 folds and nervures : base slightly pinkish, with about 

 fourteen black spots, arranged much as in P. Protca : 

 expanse of wings, 2 inches, 8 lines.

This may possibly be a form of P. Protca, although I 

 think not; the Bembe specimen approaches more closely 

 to the Natal species than the type from Ambriz, the second 

 median branch of primaries being broadly bordered with 

 dusky so as to cut off the end of the subapical fasciole, 

 leaving it as a spot upon first median interspace.

 5, figs. 28 and 30 (1867). 



Intermediate in character between P. Umbra, Drury, (of 

 which we have a pair) and P. Alcincoe, Felder* (of which 

 we have three males, one female, and a pupa-skin) ; it 

 is distinguished from both by the more perpendicular 

 and differently shaped band of primaries, which in the 

 female is ochreous, and by the dark basal half of the same 

 wings : expanse, 3 inches, 4 lines. 

 Gaboon (Pu Chaillu) (?, ? . B.M. 



A very distinct and well marked species, the sexes of 

 which were riglitly divined by Mr. Hewitson, although he 

 scrupled to separate it from the perfectly constant P. Euryta 

 of Linnainis : of the latter species we have three males and 

 tM'o females, all from Sierra Leone : I have no doubt what- 

 ever that the two insects figured at pi. iv., fig. 26 and pi. v., 

 fig. 31 are also sexes of a fine distinct species allied to 

 P. Euryta, for which I propose the name of P. Excisa : Mr. 

 Hewitson gives Congo as its locality.
