African Species of the Genus Acraca. 187 



a second sjiot near median at about two-thirds of the distance 

 from base to origin of 2. 



H.-w. with a slight dusky basal sufTusion and a black 

 hind-marginal border varying from 1 to 2 mm. in breadth 

 and very rarely showing traces of ]jaler internervular mark- 

 ings. Black spots very small and more easily observed on 

 underside. Those near inner margin sometimes only faintly 

 indicated. 



Underside. F.-w. paler and duller than above and rather 

 glossy. A small basal and subbasal spot on costa. Apical and 

 hind-marginal areas ochreous with orange internervular rays. 

 Sjiots as on upperside. H.-w. pinkish ochreous. A very 

 narrow black line round hind margin, followed by a band of 

 greenish ochreous corresponding in width to the black border of 

 the upperside and divided by narrow internervular black 

 arches. This marginal border is followed by internervular 

 splashes of orange, and the basal and median portions of wing 

 bear internervular rose pink marks. Black spots very small 

 and slightly variable. A discal row beginning with one in 7, 

 6, 5, and 4, the fourth much further from margin than the third. 

 Very rarely a minute dot in 3. I have never seen a ^ with a 

 spot in 2, though there is sometimes a very small one in the 9 • 

 In lea spot at base, a second just before origin of 2, and a third 

 half way between the second and the margin. In lb two sj^ots 

 near middle, in la one near base and one near middle. In 8 a 

 spot near precostal, beyond this in 7 a transverse spot. A spot 

 at base of 7, two in cell and one on middle discocellular. 



Wet season exami)les have a general tendency to a richer 

 colour and more dusk)'' suffusion especially of the f.-w. 



Head black with a brown tuft between the eyes and two on 

 the collar. Thorax l)lack with lateral brown hairs and two 

 dorsal whitish streaks. Base of abdomen black with orange 

 lateral spots. Remainder orange. Claws unequal. 



5 . Expanse 60-66 mm. Dry season form : — F.-w. Costa, 

 base, and inner margin more or less heavily suffused with umber 

 brown, median area rosy red, apex and hind margin brownish 

 ochreous. A black tip at apex narrowing suddenly below 

 nervule 7 but continued along hind margin as a line broader 

 than in ^. Ends of nervules heavily marked with black. The 

 whitish transparent patch conspicuous. Black spots as in ^ and 

 usually an additional spot in cell at about the middle. H.-w. 

 rosy red suffused with brownish black at base. Hind margin 

 black about 3 mm. broad and bordered inwardly by a band of 

 brownish ochreous on which the nervules are heavily dusted
