30 DR. W. J. HOLLAND ON THE AFKICAN [Jan. 14, 



.unmistakably separated from the others by the markings of the 

 underside of the secondaries as represented in the photographic 

 representation of suhstrigata given by me in the ' Entomological 

 News' for January, 1894. AVhether 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 placichis iu the 

 present paper, although inclined strongly to take this view.

Acleros higuttulus, Mab. Bull. Soe. Ent. Prance, (6) vol. ix. 

 p. clxvii (1889). 



Hab. Freetown, W. Africa (Malille). 



Fi"om the brief description of the species given by Mons. 

 MabiUe, this species appears to me to be very near A. placiO.us, 

 Ploetz (<i. v.). 



112. A. SUBSTKIGATA, HoU.

Hah. Valley of the Ogove. 



This is possibly a form oi plaeidus, Ploetz, as I have intimated

 Berl. Eut. Zeit. 1893, p. 260.' 



Hob. Loango (Ploetz), Togoland (Karsch). 



Ploetz in his catalogue of the species of Apaustus, given in the 

 Stett. Ent. Zeit. 1884, 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, pi. 744, shows that in 

 form and pattern of marking oImis is indeed very near to leuco- 

 pyga, Ploetz (ploetzi, Mabille) ; the main difference being the 

 spots in the primaries noted by Ploetz in his original description. 

 ■ An exammation of the figure of Ploetz makes it plain, furthermore, 

 that the type was a female. It seems do me quite possible that 

 the insect desciibed was a female of the species previously 

 described by Trimen as Pamptldla (?) mackenh. Karsch ajjpa- 

 rently is not sure of his identification of this species as given iu 

 his article in the Berl. Ent. Zeit. quoted in the synonymy above.
