New Forms of the Genus Char axes (Ntjmphalidae) 337 



the cell, formed of curved marks divided by the veins, and distally 

 curved at the middle. A postdiscal line of curved marks nearly straight 

 from vein 7 to submedian fold, followed by a heavy dark line, the inter- 

 space forming pale spots. White submarginal spots as above. 



The specimen is worn so much that the more obscure markings and 

 true colour cannot be diagnosed. 



Length of fore w T ing : 46 mm. 



Sumbawa, September, 1891, one 5 . Collected by W. Doherty. 



NOTE ON SYNONYMY. 



4. Charaxes brevicaudatus Schultze. 



Arch. Naturges. 79 Bd., Abt. A, p. 3, t. 1, fig. 3 (1914) (Nyasa- 

 land) 2 . 



Bebel, Ann. K.K. Nat. Hofmus., Bd. xxviii, p. 254, pi. xx, figs. 21, 22 

 (1914) (N.W. Tanganyika, Iringa and Nyasaland) 3 . 



Charaxes maudei Joicey and Talbot, P. Z. S., 1917, p. 271 (1918) 

 (" German E. Africa ") ? . 



We have acquired a 3 of this form from Tanganyika territory 

 which agrees with the figure given by Eebel. It is undoubtedly the 3 

 of the ? described by us as maudei, the figure given by Schultze only 

 differing in being a little darker. The tails of our ? specimen 

 are long. 



We prefer to treat this form as distinct from ci thaer on Feld., which 

 occurs in the same area, and since both sexes are constantly different it 

 is probably another species allied to xiphares Cram. 



5. Charaxes penrici Boths. 2 . 



Nov. Zool. vii, p. 460 (1900) (Quebe Biver, Angola) 3 . 



C. peculiaris, Lathy, Entomol. xxxix, p. 125 (1906) (North-East 

 Bhodesia). 



? . Bands with reduced blue, on the fore wing with but slight blue 

 edging or none. Band broader on the hind wing and posteriorly 

 broader on the fore wing. 



Underside paler with extended white markings. 



Length of fore wing : 47 mm. 



Nyasaland (2 neallotype), also one other ? from Mrowi, Nyasa- 

 land, and 3 3 from Nyasaland, East Africa and Katanga. 



The form described by Lathy is not constant, as transitions occur 

 from blue to green, and variations of the other markings.
