form of p. eharina. I am quite sure that all collectors of South- 

 African species will dissent from his last suggestion, because the 

 wet, intermediate, and dry phases of P. eharina are well known, 

 and (apart from size) can readily be distinguished from P. simana 

 by the uniform character of their upper surface at all seasons, and 

 by the absence of the black veins on the upper surface and the 

 black discal spot on the under surface of the male primaries. We 

 do not possess the wet phase of P. gerda, in which the outer 

 border attains to a width of 4 millimetres ; but even the 

 intermediate phase has a wider border than the wet phase of 

 P. simana ; and in all the specimens now received the grey at the 

 base of the primaries is rather more diffused and the black veins 

 are obliterated almost to the outer margin, bringing the species 

 nearer to P. eharina excepting for the black discal spot of the male 

 and the absence of the dense speckling which characterizes the dry 

 phase of the Natal species ; the primaries in P. gerda are somewhat 

 shorter, and therefore less acutely triangular, than those of 

 P. simana. 



Before leaving Pinaeopteryx it is perhaps as well to point out 

 that " Lvias venatus " proves to be a female of a species undoubtedly 

 referable to this genus, and apparently most nearly related to 

 P. liliana ; it certainly has nothing to do with Belenois.

E. of Athi E., some 4300 feet alt., Kitwi, 18th December, 1898. 



" Undulating uplands, timbered with thorny scrub and very dry. 

 This is, I think, an insect very familiar to me in British Central 

 Africa." 



Mr. Crawshay obtained examples of this species at Machako's, 

 in British East Africa, but not in Nyasa-land ; he is probably 

 thinking of S. synestalmenus.
