African Sjiccirs of tlicGcnus Acraca. 53 



costa. Slightly darker suffusion at apex caused by a reappearance 

 of scales which however are still very narrow and elongated. 

 A reddish basal suffusion (probably bright red in fresh 

 examples) extending to nearly half the length of the cell and 

 distally to nearly the whole length of area la. A black spot 

 in the cell about the middle, and two spots in area lb, one near 

 the base and one about the middle, ll.-w. black at base and 

 with a basal reddish suffusion extending a little beyond the end 

 of cell. jSTumerous black spots arranged as follows. Two in area 

 7, two in cell, and two in lb, and 2, three in Ic, one in 3, 4, 5, and 

 6, and one near the base in la. 



The underside is similar but without the reddish suffusion 

 which only shows through from the upperside. A fourth sjiot is 

 visible in Ic at the base. 



Thorax black, aljdomen black above and brown beneath, with 

 brown lateral segmental spots. Claws unequal. 



9. Expanse about 62 mm. According to Aurivillius' figure 

 {I.e.) there is a small additional spot in area 2 in the f.-w. 

 The basal suffusion is described as ochreous. 



The three $ ^ from which Aurivillius described the 

 type were taken in May and July (1891) at Bibundi and 

 t'ongc in N.W. Cameroon, and are in the Stockholm 

 Museum. There are six ^ examples in the National 

 collection taken at Fernando Po, and a few specimens in 

 the Tring collection. 



The above are the only examples known to me. The 

 female genital armature is sufficient!}^ distinct in form 

 though showing a foirly close resemblance to that of 

 A. cerasa. The transparency of the wings in this latter 

 species is however produced in a different manner. 

 Aurivillius regards kraJca as a near ally of quirina, and in 

 support of this it may be noted that in both species the 

 transparency is caused in the same manner, though on the 

 other hand the structure of the respective male armatures 

 is very different.
