has a tendency to be paired ; a well-marked .short, stout, black 

 tail on vein 2. 



Underside whitish with black spots. An ochreous flush at 

 base and along costa and outer margin of primaries and whole of 

 secondaries, also some faint submarginal markings of a brighter 

 orange colour and a black linear outer margin to both wings. 



Primaries. The following black spots and striae outlined in 

 whitish : — an elongate discocellular ; a discal row of six small 

 elongate spots, the third, that in area 4, being placed more 

 distally and at a different angle to the others, the last spot, that 

 in 1 b, being small and sometimes paired. 



Secondaries. "With the following black spots and strise outlined 

 in whitish : — a large spot below costa above cell-middle, a spot in 

 middle of cell, a small spot on inner margin near base ; a discal 

 row of eight black somewhat elongate spots around cell-end from 

 costa to inner margin, the first, that in area 7, being very large ; 

 those in areas 3 and 2, of which the former is very small, placed 

 nearer cell than the remainder ; the penultimate, that in area 



1 c, more elongate and more distally placed. Eye-spots in areas 



2 and 1 c much as upperside, but that in area 2 has a complete 

 blue iris and is secondarily strongly outlined externally with 

 black. 



Fringe dusky : palpi white tipped dusky ; thorax and abdomen 

 dusky above, paler below (the vertex tinged with bronze). 



Length of primary 22 mm. 



The female is a larger insect, primary 24 mm. The golden- 

 bronze colour of the male is lacking and the upper surface is 

 washed with pale blue, and there are traces, especially in 

 the secondaries, of a submarginal row of whitish arrow-shaped 

 markings. A variable number of the discal row of .spots on the 

 secondaries is visible on the upper surface. In the type specimen 

 figured, these are seen in areas 4 and 5. The eye-spots on the 

 upper surface are faintly outlined with orange-ochraceous. The 

 under surface resembles that of the male, but is paler. There 

 is sometimes an additional black spot immediately below the cell- 

 middle in area 1 c. 



Types J $ i n the British Museum, from the Mansya river 

 near Lake Young, 5.xi.08. 



Ootypes in the Hope Coll., Oxford. 



Described from eleven males and thirteen females from the 

 Chambezi valley and Mansya river, mid-October-mid-November, 

 1908, and one worn female from the Lufupa river, 26.X.07. 



This striking species seems most nearly allied to C. pectdiaris 

 Rogenh. in the distribution of its markings, agreeing with 

 C. gigantea Trim, in the possession of a tail. Apart from the 

 colour of the male, it differs from allied species in the blue, not 

 orange, colour of the eye-spot and in the possession of a disco- 

 cellular spot on the upper surface of the secondaries. 



This species has a fairly strong flight, and it frequents open 

 country on the edge of patches of woodland.
