African Species of the Genus Acraca. 245 



suffusion at base nf wing. Sometimes a spot in lb near middle. 

 H.-w. slightly Ijlackened at base, and having a black hind-mar- 

 ginal border about 2 mm. wide upon which are ovate spots of 

 the ground-colour which sometimes reach the margin. Just 

 before middle of wing there is an indication of a double curved 

 band of linear spots corresponding to those beneath. A linear 

 spot on discocellulars more distinct than the others. 



tJnderside, f.-w. Basal half orange tawny but paler than 

 above, darkest along subcostal. The subapical patch indi- 

 cated in ochreous yellow. Costa, apex, and hind margin 

 greyish ochreous. Apical and hind-marginal areas striated by 

 the black ends of nerviiles and internervular orange streaks. An 

 irregular transverse black mark extending from costa just beyond 

 end of cell partly into area 3. A narrow black marginal line. 



H.-w. Pale ochreous, area 9 pinkish. Just before middle of 

 wing a curved double row of linear transverse spots between 

 the nervules enclosing in 7, cell, and Ic a red patch. There is 

 also a spot in 8 against precostal, a basal spot in cell, and in Ic. 

 The marginal border formed as follows : — The ends of nervules 

 are black and there is a narrow black marginal line upon which 

 stands a series of finely black triangles enclosing ochreous trian- 

 gular spots. The apices of these triangles are produced inwardly 

 into broad red internervular marks. This pattern is much 

 narrower in 4 and 5 than elsewhere, so that the border is at 

 that point deeply invaded by the ground-colour. The inner 

 edge of the border may be clearly defined by a fine black line. 

 Head black with a pale mark between the eyes, two reddish 

 tufis on collar, thorax black with a few pale markings. Ab- 

 domen black above with pale ochreous lateral spots and segmental 

 lines. 



9. Expanse 50-60 mm. Resembles the ^ fairly closely 

 but the ground-colour varies from rather duller to dusky 

 ochreous. The black spot in f.-w. lb more generally present 

 and often in the form of an irregular streak. H.-w. has the 

 marginal spots larger and the discal spots more distinct. The 

 black nervule ends and the more clearly defined inner edge 

 of the underside marginal jiattern are distinctly visible on the 

 upperside. 



The underside is very like that of the ^ , but the h.-w. discal 

 black spots are thicker and the inner edge of the marginal 

 pattern is distinctly defined by a black line. 



I can find nothing in Weymer's fig. of " terpsicJiorc 

 vnr. hnJvoha" to distinguish it from this form, the only
