Hab. E. Arrica*® (C, 8. Betton), 30 miles from Magadi 
Junction (fF. G. Hamilton), Kibwezi (alt. 3000 ft.), Nairobi 
to Fort Hall Road (alt. 4500-5000 ft.) (S. dA. Neave) ; 
N. Nigeria, Panyam in Banchi Province (G. F. Fow). 
About 200 examples of this species are contained in the 
Museum collection, including specimens from the two 
localities quoted by Gerstaecker, Mombasa and Natal. The 
variety tripartita was received with the typical form from 
Kibwezi, five of the thirty examples before me being inter- 
mediate, having the prothorax partly red. The long series 
from the slopes of Kenya (6000-8500 ft.), and those from 
the Karonga district of Nyasaland are also darker than 
typical dimidiata, having the apical half of the elytra and the 
scutellum black, these specimens (39 ¢ 2,5 3 ¢) forming 
a transition to the still darker ¢ripartita. Some of the 
southern examples (3 @? ) have the elytra distinctly angulate 
at the sutural angle, a character apparently of no great 
importance. Males of each form have been dissected, 
showing a similar genital armature. ‘The tuft of long hairs 
behind the eyes mentioned by Pic in his description of 
I. tripartita is to be found in all the allied African species 
known tome. His I. nigricollis (1906), from Sierra Leone, 
is not represented in the collections at the Museum.
