67. Acr.t;a periphanes. 



AcrcBci 2jeriphanes, Oberthiir, Etudes d'Entom. livr. xvii. p. 20, 

 pi. 2. fig. 23 (1893). 



One example, Lake Mweru. 



Our example is better marked than that of M. Oberthiir, all the 

 spots of the under surface of primaries being strongly defined on 

 the upper surface ; the secondaries below more distinctly marked 

 with rosy vermilion on abdominal border, where there is one 

 additional black spot. There can be no question whatever that 

 these differences are due to simple individual variation. 



In the same livraison M. Oberthiir has described a number of 

 species as new upon which Dr. Holland has recently commented 

 in his paper in the ' Annals of Natural History.' I quite agree 

 with him in his statement that all the varieties of A. proteina 

 and A. hilimandjara are sports of A. johnstoni, Godmau. I also 

 consider A. cappadox to be=-4. honasia, A. straUipocles S = 

 sambavce, "Ward ; A. conradti=])r6hab\y a variety of A. fornax, 

 Butl. ; A. serena-melas a melanism of A. honasia ; A. c7icerihula^= 

 n. sp. near to A. caldarena- A. masaris 5 =A. monteironis, Butl. 

 A. regalis is allied to, but distinct fi'om, A. hrcesia, Godm. We 

 have the species represented in the Museum collection. 



Of other Acrceas recently described to which attention should be 

 drawn are A. alhomaculata, Weymar, Stett. ent. Zeit. 1892, p. 82, 

 which is=^. lirjus^ Druce, and A. omhria, Weymar, I. c, which 

 is =^. caldarena, Hew.

Acrcea caldarena, He\^dtson, Ent. Mo. Mag. xiv. p. 52 (1877).

 figs. 1, 2 (1881). 



Acrcea omhria, Weymar, Stett. ent. Zeit. 1892, p. 82. 



S $ , Zomba, July 1892 ; S , Lake Mweru. 



I cannot agree with Trimen in referring A. nelusca to A. 

 douhledayi : in the first place the male, although with a shghtly 

 smaller black apical patch than usual to the primaries, also lacks 

 the longitudinal grey streaks on the internervular folds, A\'hich are 

 very characteristic of A. douhledayi J ; the female, moreover, is 

 quite typical, and, as Trimen says, in it " there is no trace whatever 

 of the subapical whitish bar of douhledayi $ ." In the present 

 collection one female corresponds with Oberthiir's figure, whilst 

 another is smoky grey, with the central third of the primaries 

 occupied by a broad oblique snow-white belt.
