black legs and the appendages, the long inferior appendages 

 of G. hhasiaca being remarkable. 



De Selys (Ann. Soc. Exit. Belg. xxvii. p. 128, 1883) alludes 

 to a G. nigripes from Thibet as having very acute append- 

 ages and no markings at the base of the wings, but with no 

 further indication of characters. 



Gynacantha bullata, Karscli. 



Of this I possess two males and two females from " Came- 

 roons " (Rutherford), one male from " Mahambe " (Ruther- 

 ford), one male from Cape Coast Castle, and one male from 

 " West Africa," without further indication of locality. They 

 vary considerably in size, but the characters remain very 

 distinct. In very mature examples the wings are strongly 

 brownish fumose. The oreilettes are usually wholly black, 

 but yellow margined with black in less mature individuals. 

 (A very immature male and female from Sierra Leone are 

 slightly doubtful.) 



N.B. — jEshna africana, Pal. de Beauv. (Ins. Afr. &c. 

 p. 67, pi. iii. fig. 1). The figure indicates a somewhat large 

 Gynacantha (probably female), larger than G. bullata; what 

 it really is will probably remain problematical, for I am not 

 aware that the type is extant.
