Papilio polydorus ulatvaensis, subsp. n. or aberr. n. 



The types of the forms herein described are in the collection 

 of Joicey. 



Papilio illyris hamatus, subsp. n. 



<5 . Upperside with broader bands. Fore wing with band 

 strRighter on its outer edge. Hind wing with a bar at the end 

 of cell, almost cutting oft' a cell-spot. 



Underside with reduced red on the hind wing ; the red line 

 fringing the black spot in 7 is very narrow, and the black spot is 

 reduced to a straight bar; white spot beyond cell enlarged and 

 entering the cell.

Charaxes maudei, sp. n. 



Allied to xiphares Cram, and cithceron Feld., and perhaps 

 linking these two species together. 



5 . The upperside resembles cithceron and the underside more 

 like xiphares. Much larger than any females we have seen of 

 these two species. 



Upperside of fore wing with a broad white discal band, broken 

 where 1 c, 2, and 3 cross it, the spot in 3 larger than the others, 

 in 1 c smaller than the spot below it ; 3 subapical spots as in 

 cithceron, followed by 6 spots in 5, 4, 3, 2, 1 c and 1 b, forming a 

 subterminal series of fulvous spots, the two upper ones being 

 white proximally, the two lower ones placed close to the lower 

 median white patches. Hind wing with a broad white discal 

 band formed as in cithceron, its distal edge with diffuse purplish 

 scaling; a postdiscal series of 5 fulvous spots in cellules 2-6, 

 the anterior one touching the discal band ; a subterminal series 

 of small violet spots ; marginal lunules thicker than in the two 

 allied species, the anterior 3 f ulvous, the posterior 3 dull green. 



Underside with greener ground-colour than in the allied 

 species. Fore wing with discal band continuous, its proximal 

 edge indented so that the black line is strongly curved in the
