32 DR. W. J. HOLLAND ON THE AFRICAN [Jan. 14, 
of Jong hair-like scales; hind tibiae almost naked and with two 
pairs of spurs. 
Type G. abure, Ploetz. 
115. G. anuraz, Ploetz. 
Apaustus abure, Ploetz, S. E. Z. vol. xl. p. 359 (1879), vol. xlv. 
p. 153 (1884). 
Hab. Tropical West Africa. 
G. DIVERSATA, var. nov. 
This form differs from typical G. abure, Ploetz, in being pre- 
valently lighter in colour on the underside of the primaries and 
the dise of the secondaries, the darker outer third of the second- 
aries remaining as in the typical form, and giving the appearance, 
therefore, of a dark diffuse hind marginal border to the wing. 
This form is quite common. About one-half of the specimens 
collected for me in the Valley of the Ogové belong to it, but I 
cannot lead myself to believe that it represents a species. Save in 
the colour modification noted, the specimens otherwise agree 
absolutely with G. abure, and there are a number of intergrading 
forms. (See neat species.) 
116. G. HeTEROCHRUS, Mab. 
Pamphila heterochrus, Mab. Ann. Soc. Ent. France, (6) vol. x. 
p- 31, pl. iii. fig. 7 (1890); Novit. Lepidopt. p. 116, pl. xvi. fig. 4 
(1893). 
Gastrocheta dwwersata, Mab. MS., in coll. Staudinger. 
Hab. Tropical West Africa. 
The figure of G. heterochrus in the ‘ Novitates,’ was drawn from a 
specimen in the Staudinger collection, which has been labelled 
Gastrocheta diversata by Mons. Mabille. Another specimen 
which does not at all agree with the figure in the ‘ Novitates,’ and 
the duplicate of which was pronounced by Mons. Mabille himself 
to be a hitherto undescribed species, is labelled in the Staudinger 
collection as the type of G. heterochrus. There has plainly been 
a misplacement of the labels. I have therefore taken the liberty 
of applying the name proposed by Mons. Mabille to this new 
form, of which there are numerous examples in my collection, 
and which is plainly a mere colour variation of G. aburw, Ploetz 
(vide supra).

Hab. British Central Africa (Butl.); French Congo (Good). 
I have several specimens of this little species from the Valley of 
the Ogové, agreeing absolutely with the type. It is closely allied 
to the species described herein as G. minima, Holl., but may be 
distinguished at once by its somewhat larger size, and the fact
