compared with the postdiscal series, is not meutioned liy Dr. Butler. As pri/icejjs 

 applies, therefore, to the same race to which the name of smaragdalis was originally 

 given, the north-western race recjuires a name.

cJ. Wi»f/s (ibore. Forewing : discal spots very much larger than the post- 

 discal ones, s])ot M' — JP at least twice (mostly three or four times) as large as the 

 respective postdiscal one, separated from it, obliquely concave distally; patch M' — M' 

 complete or subdivided by one or two black spots into a larger discal and smaller 

 postdiscal portion, its outer edge mostly biconcave, 2i to 3i mm. from edge of wing 

 before SM', breadth of patch 5i to 12 mm. ; postdiscal spots li' — M' often minute ; 

 outer edge of wing sometimes very feebly concave, and the apex less acute than in 



the north-western race, but this character is quite inconstant. Hindwiug : blue 



area expanded between SC" and abdominal fold, patch SC'^ — R' not seitarated, but 

 often reduced in width; in front of SC there arc two spots, often merged together to 

 one large patch which is generally sinuate in front, but is occasionally complete, 

 proximal spot seldom obsolete, blue one much extended distad, in many specimens 

 reaching blue admarginal spots, in which case the black area between blue patch 

 and admarginal spots is posteriorly divided into more or less small spots in which 

 are situated the white and blue snbmarginal dots. 



Underside : median bars R- — M" of forewing strongly concave, bars M- — SM' 

 very heavy, fused to a W-shaped mark. 



?. Wings, above. Forewing: band 2 to 3 mm. from outer margin before 



SM^ ; a series of jjostdiscal spots, upper two larger and white, the others minute 



and blue. Hindwing : blue area extended distally as in S , the black outer area 



reduced in width, posterior patches more or less isolated, outer edge of blue area 

 regularly concave between veins from R' — SM". 

 Length of forewing : 6, 42 — 50 mm.

Hab. Niger to Angola and Uganda Protectorate. In the Tring Museum from: Rau, 

 Nandi Country, Uganda Protectorate, December 12th, 18US (Dr. Ansorge), 1 S ; 

 Landaua, 1 S ; Congo and Kassai Country, 6 d"c?, 1 ?. In the British Museum 

 from Victoria, Cameroons, and Congo ; in the Berlin Museum from Angola 

 (Mechow), and Old Calabar ; Dr. IStaudinger has a ? from Lambarene, Ogowe. 



In the width of patch M^— SM^ of the npperside of the forewing, the Rau 

 specimen, as said before, does not essentially differ from certain examples of 

 Ch. cithacron, being only 5i broad, the patch stands, however, closer to the outer 

 margin ; on the hindwing patch SC" — li' measures only 3^ by 4 mm., :iud the 

 patch before SC" is divided up into two well-separated spots.
