Eyes, palpi, antennae and legs as in typical Argiolaus. 



Wing shape. Fore wing inner margin more or less strongly lobed near the base, weakly in 

 menas, trimeni, maritimus , vansomereni, poecilaon, iturensis, aequatorialis, laonides and ismenias, 

 more sharply in julus, aelianas, calisto and cottrelli. Hind wing with a tooth at vein 3, a delicate 

 tail at the end of vein 2, and a longer one at ia which, in caesareus, is extremely long and 

 spatulate at the tip ; anal angle lobed. Male secondary sexual characters : as in Argiolaus, 

 namely, a hair tuft midway along the inner margin on the underside of the fore wing, and an 

 androconical patch, small to large, on the upperside of the hind wings near the base. 



Wing venation. Exactly as in Argiolaus, fore wing with 12 veins in the <£, 11 in the $. 



Male genitalia (Text-fig. 116). Uncus composed of two subtriangular lobes separated by a 

 slight depression of the margin of the tegumen ; subunci short, stout, gently curved. Tegumen 

 subrectangular, hood-shaped ; vinculum broad ; lower fultura formed of two large laminae, 

 broader at their extremities and with their basal halves fused together ; valves long, narrow, 

 curving, with rounded apices ; penis very stout, more elongate than in Argiolaus, the inner 

 part widely open dorsally, the outer part rather short ; vesica enclosing two stout unequal 

 spines : uncus and lower fultura pilose, valves almost naked. 



The male genitalia of menas are evidently of the ordinary Thecline type, pro- 

 foundedly different from typical Argiolaus. The armatures of the other Iolaphilus 

 are certainly not all identical with those of menas either, but the general plan is the 

 same. The following differences can be indicated : — 



a. Subunci weakly curved : menas, henryi, trimeni, schultzei, julus, aelianus, 

 iturensis, maritimus, alcibiades, paneperata, lukabas, ndolae, ismenias, vansomereni 

 and aequatorialis. 



b. Subunci very bent : gabunica, caesareus, calisto, laonides and poecilaon. 



c. Lower fultura composed of large laminae : menas, henryi, trimeni, schultzei, 

 julus, aelianus and gabunica.
