area 7 of the h.-w. arc closer together than in iieneleos, 

 whilst finally, though the male armature is, like that 

 (jf several allied forms, simple in structure and but 

 little distinctive, it appears to present certain constant 

 diftorences. The acquisition of a ^ specimen may help to 

 decide its true affinity. In the meantime I prefer to keep 

 the Ibrm separate from jjcnokos, vmder the name which the 

 late Dr. Staudinger proposed. That author's example is de- 

 scribed as from the Upper Congo, without precise locality. 

 One of the Tring examples is labelled Aruwimi, and the 

 other Luebo, Kassai River. These localities are rather far 

 apart, the latter being apparently some 750 miles S.W. of 

 the former. The two examples do not, however, appear 

 to differ in any noticeable particular. In addition to these 

 two specimens there are also in the Tring collection several 

 examples taken near Ft. Beni in the northern part of the 

 Congo region. These I must refer to the same species. 

 They differ only in having a browner ground-colour, atid 

 in the h.-w. a duller shade of red.
