3i8 UNDER THE AFRICAN SUN 



Compsoinera ajisorgei, sp. nov. (Plate I. fig. 3). 



This species is very closely allied to Compsomera nigricollis 

 Gah., which it resembles exactly in the markings of the elytra, 

 with the exception that the metallic-blue colour in the type of 

 Compsomera nigricollis is here replaced by metallic-green. It 

 differs chiefly from Compsomera nigricollis in having the head, 

 legs, and antennae quite black in colour. 



Long. 26, lat. 7 millim. 



Only one specimen, caught in Uganda. 



(L) One butterfly (described by the Hon. Walter Rothschild). 

 Vide "The Entomologist," June 1897. 



Papilio inivietiais, sp. nov. 



It belongs to the family Papilionidsi. This most remarkable 

 butterfly is closely allied to Papilio rex Oberth. ; but while that 

 species is almost the exact mimic of Melinda formosa Salv. and 

 God., Papilio mimeticus mimics Melinda morgeni mercedonia 

 Karsch. 



5 Forewings : differ from Papilio rex in having the basal 

 area deep chestnut instead of orange-rufous ; in this chestnut 

 area is a longitudinal pale streak behind cell, not present in 

 typical Papilio rex. 



Hindwings : One of the most striking dift'erences, however, 

 between Papilio rex and Papilio mimeticus is that while in Papilio 

 rex the ground-colour of the hindwings is uniform black, in 

 Papilio mimeticus the disc of the wing is dull chestnut, this 

 colour extending along the abdominal margin to near apex of 

 vein. 



Underside : The two anterior white marginal spots of Papilio 

 rex are absent in Papilio mimeticus. 



Oberthiir, in his original description of Papilio rex (Bull. Soc. 

 Ent. Fr. 1886, p. 114), says "Abdomen black above, white on 

 sides and below;" but in the specimen of Papilio rex from Uganda 

 Protectorate the underside is black, with a narrow but distinct 

 median white line, and in this agrees entirely with Papilio mime- 

 ticus. 



It was caught at a streamlet which crosses the caravan route 

 not far from Msarosaro in Uganda on December 28, 1896.
