H. STEMPFFER 



Genus SYRMOPTERA Karsch 



Syrmoptera Karsch, 1895, Ent. Nachr. 21 : 308. Type-species : Syrmoptera melanomitra 



Karsch, by original designation. 

 Oxylides (partim) ; Aurivillius (nee Hiibner), 1898 : 312 ; 1922 : 381. 



Eyes naked ; palpi distinctly protruding beyond the frons, second segment laterally com- 

 pressed, clothed with large white scales, third segment fairly long, acuminate ; antennae about 

 half as long as the costa, black and white-annulated, each segment much longer than wide, a 

 well differentiated cylindrical club ; thorax clothed below with white silky hairs ; legs : tibia 

 and tarsi black and white-annulated, o* fore leg with femur clothed with white hairs, tibia 

 shorter than femur, tarsus unsegmented. 



Wing shape. Fore wing more triangular than in Oxylides, the apex less rounded ; hind 

 wing with three long slender tails, one each at the ends of veins 3, 2 and ib, those at 2 and ib 

 subequal, the one at the end of 3 decidedly the shortest. 



Wing venation (Text-fig. 286). Fore wing with only 10 veins. 



Male genitalia (Text-fig. 104). Uncus composed of two subtriangular lobes ; subunci very 

 robust, curved, without apical hook, on the lower edge in the distal third with a strong, blunt 

 tooth ; tegumen very large, posterior edge with a rounded depression ; vinculum fairly broad 

 prolonged to form a large saccus ; lower fultura representated by a small lamella hollowed out 

 at the apex ; valves much reduced in size, broadly fused to the vinculum and ending in a small 

 rounded lobe ; penis elongate, proximally swollen and Mask-shaped, cylindrical and slightly 

 curved externally with a slightly dilated apex ; a few hairs on the uncus and on the apices of 

 the valves. 



The male genitalia of 5. homeyeri, S. amasa, S. nivea and 5. bonifacei are almost 

 identical with those of S. melanomitra. Only the form of the valves differs from one 

 to another. 



The genus Syrmoptera is very close to the genus Oxylides, the only difference being 

 in the shape and colour of the wings.
