African Sjyecics of the Genus Acraca. 175 



or 5 the black tapers to a narrow marginal line extending to 

 the hind angle. The median area is often rather thinly scaled 

 but does not become translucent. A slight dusky suffusion at 

 base. The apical and liind-mari;inal area shows a tendency to 

 orange between the nervules, and in the internervular spaces 

 are black rays sometimes as far as area 2. Ends of nervules 

 black. There is a snbmarginal row of black spots parallel to 

 the hind margin. These vary in number. In very " dry " 

 examples there may only be a minute spot in lb and 2, while 

 wet season specimens may have a well-developed row of four 

 spots in lb, 2, 3, and 4. Other spots as follows : — One in cell 

 above origin of 2, sometimes preceded by a faint longi- 

 tudinal streak. A double spot on upper part of discocellulars. 

 A discal row, when all present five in number, in 10, 6, 5, 4, 

 and 3, but that in 6 often minute or absent. These spots lie 

 roughly in a straight line nearly at right angles to the costa ; 

 the spot in 3 well sejiarated from the others. In area 2 a spot 

 near the meridian. In area lb a subbasal and a median spot. 



H.-w. A slight black suffusion at base and a hind-marginal 

 border varying in appearance from continuous black about 

 2 mm. wide to a row of faintly indicated dark internervular 

 arches standing on a thin marginal line. The inner edge of 

 this border is always regularly arched between the nervules. 

 Black spots as on underside, those near inner margin often very 

 faint, and the discal spots often smaller than those below. 



Underside. F -w. a pale replica of the upperside but with- 

 out the apical black. Two small black spots near base of costa. 



H.-w. Pinkish ochreous with internervular marks of a rather 

 deeper pink in median and basal areas. Hind-marginal border 

 bright ochreous with a thin marginal line and narrow black 

 internervular arches. Black spots as follows : — A discal row of 

 eight. The first three in 7, 6, and 5, approximately parallel 

 to margin, the fourth in 4 close to end of cell, the fifth in 3 

 some distance from end of cell, but not in the middle of the 

 area, the sixth in 2 close to median, the seventh in Ic nearer 

 margin, and the eighth in lb nearer base. A spot in 8 near 

 precostal, a subbasal in 7, two in cell close together near middle, 

 one at base of area 5 touching m.d.c. and 6. A large subbasal 

 spot in Ic, and close to it a spot in lb, and la, all three in a 

 straight line, a subbasal spot in la and some irregular black 

 about bases of nervures. 



Head black with brown hairs, and tufts on collar. Thorax 

 black with brown hairs. Base of abdomen black with orange 

 lateral spots, remainder orange. Claws unequal.
