wing, on the black ground-colour of phlaeas, and is distinct 
in the Uganda forms.* Two abboti collected November 20-21, 
1910, by Dr. 8. A. Neave on the slopes of Mt. Rungwe 
(5-6000 ft.), near New Langenburg, 8.W. Tanganyika 
Territory, are transitional in their incomplete attainment of 
the characteristic brilliant red. 
Other differences between the hind-wings are only apparent. 
The zigzag row of black discal spots and the prominent, 
black, disco-cellular mark which seem to distinguish the 
hind-wing upper surface of abbott from that of phlaeas are 
also present in the latter form and can be easily made out, 
by their intenser blackness, upon the dusky surface of the 
wing. Even the pale blue spots commonly present just 
inside the red marginal band of phlaeas can be detected, 
white against the red background, in some specimens of 
abbott. Furthermore, Dr. Eltringham, examining the spots 
with the binocular microscope, found blue scales among 
the white, and agreed with me that there was no doubt about 
the markings being homologous. 
In addition to Dr. Carpenter’s specimens, Mr. Talbot 
informs me that the Hill Museum, Witley, possesses the 
following examples collected in 1919 by Mr. T. A. Barns :— 
Kissenji, Kivu, Sept. & Oct.—2 ¢ 1 9; Lake Tshohoa, 
Ruanda Distr., Aug.—l ¢; Upper Akanjaru Valley, Urundi 
Distr., July & Aug.—1 31 9. 
The small structural differences described by Dr. Chapman, 
together with the tint of the hind-wing below, make it clear 
that the two African forms are geographical races of the 
Northern phlaeas. In Africa itself, the difference in dis- 
tribution and in the colour of the hind-wing above enables 
us to distinguish the following subspecies :— 
(1) Heodes phlaeas abboti Holl., common at an elevation 
of about 6000 ft. and higher, in Kenya Colony and Tanganyika 
Territory. 
* A British example captured in the summer of 1921, and shown at 
the meeting of the 8, Lond. Ent. Soc., Noy. 24, 1921, by Mr. L. W. 
Newman, approaches abboti far more closely than any of Dr. Carpen- 
ter’s Uganda specimens, The red iridescence on the hind-wing upper 
surface was strong enough to render the black spots markedly 
conspicuous.—KE. B. P.
