A. i>erip]ianes, f. acritoides. PI. Ill, f. 11 {$)■ 



Difters from typical examples in having more elongated wings, 

 and in the absence of the apical black patch and the discal spots 

 of the f.-w. These differences have the effect of giving the 

 insect a very close resemblance to A. acrita as already noted by 

 Neave (Proc. Zool. Soc, p. 20, 1910). Of this form I have only 

 seen male examples. 



Examples of A. periphanes from the Alala plateau, 

 N.W. Rhodesia, present much the same series of forms, 

 but the specimens are generally of smaller size. 



The extraordinary formation of the male genital arma- 

 ture in pcripfhancs separates it very definitely from allied 

 species. 



The different forms above described are neither seasonal 

 nor geooraphical unless Angola produces only the form 

 leni. Even then the latter could not be regarded as a 

 subspecies since it also occurs in other localities. It is 

 a curious fact that dead and dried examples of this species 

 usually have the last three or four segments of the 

 abdomen sharply bent downwards and forwards.

^ . Expanse 60 mm. Rich golden yellow with black spots 

 and markings. F.-w. narrow and pointed, base very slightly 

 suffused with black ; ground-colour of basal portion of a some- 

 what richer tint than the remainder : costa very narrowly 

 black except at base ; subcostal, nervule 6, and distal ends of 

 remaining nervules black. Hind margin narrowly black, ex- 

 panded into small triangular marks at ends of nervules. A 

 large ovate transverse spot in cell above origin of 2. A sub- 

 quadrate spot on iipper part of end of cell. A little beyond 

 cell an outwardly convex row of five rather small rounded 

 spots ; beneath these nearer to base, and between nervules 2 

 and 3, a rounded spot ; below this and slightly nearer margin a 

 small, rather crescentic spot, and a verj'' small subbasal spot in 

 area lb close to median. 



H.-w. rather paler than f.-w. ; a moderately heavy black basal 

 suffusion ; in area 7 a subbasal spot followed by a larger trans- 

 verse spot near middle of costal margin ; beneath this but
