30 DR. W. J. HOLLAND ON THE AFRICAN [Jan. 14, 
unmistakably separated from the others by the markings of the 
underside of the secondaries as represented in the photographic 
representation of substrigata given by me in the ‘ Entomological 
News’ for Jariuary, 1894. Whether all of these belong to one 
and the same species remains to be proved, but the presumption 
seems to me to be in favour of this view. I do not, however, sink 
Mabille’s species and my own as synonyms of placidus in the 
present paper, although inclined strongly to take this view. 
111. A. BreurruLus, Mab. 
Acleros biguttulus, Mab. Bull. Soc. Ent. France, (6) vol. ix. 
p- clxvii (1889). 
Hab. Freetown, W. Africa (Mabille). 
From the brief description of the species given by Mons. 
Mabille, this species appears to me to be very near A. placidus, 
Ploetz (q. v.). 
112. A. supsrrieata, Holl. 
Acleros substrigata, Holl. Ent. News, Jan. 1894, p. 28, pl. i. 
figs. 10, 11. 
Hab. Valley of the Ogove. 
This is possibly a form of placidus, Ploetz, as I have intimated 
above. 
113. A. onavs, Ploetz. 
Apaustus olaus, Ploetz, 8. E. Z. vol. xlv. p. 156 (1884); Karsch, 
Berl. Ent. Zeit. 1893, p. 260. ; 
Hab. Loango (Ploetz), Togoland (Karsch). 
Ploetz in his catalogue of the species of Apaustus, given in the 
Stett. Ent. Zeit. 18384, places A. olaus immediately before his 
leucopyga, which is strictly congeneric with the species described 
under the same name by Mabille, and made the type of the genus 
Acleros. A good copy of Ploetz’s drawing, pl. 744, shows that in 
form and pattern of marking olaus is indeed very near to leuco- 
pyge, Ploetz (ploctzi, Mabille); the main difference being the 
spots in the primaries noted by Ploetz in his original description. 
‘An examination of the figure of Ploetz makes it plain, furthermore, 
that the type was a female. It seems do me quite possible that 
the insect described was a female of the species previously 
described by Trimen as Pamphila (?) mackenit. Karsch appa- 
rently is not sure of his identification of this species as given in 
his article in the Berl. Ent. Zeit. quoted in the synonymy above. 
114. A. instapriis, Mab. 
Acleros instabilis, Mab. Bull. Soc. Ent. France, (6) vol. ix. 
p- elxviii (1889). 
Hab. Zanzibar (Mabille). 
There are two females in the collection of Dr. Staudinger,
