896 REPORT OF THE HARVARD AFRICAN EXPEDITION 
African Subregion, where it has been positively recorded from Cape Colony, 
Angola, the Katanga, Northern Rhodesia, Nyasaland, and Kenya Colony. 
Krober includes ‘“‘Uganda”’ in the distribution, but I suspect that the specimens 
which he saw were labelled ‘‘Uganda Railway,” which, of course, is in Kenya 
Colony.

Text Figure 7. — Head 
and antenna in profile of Chry- 
sops neavet Austen, female 
This species is known only from the Kundelungu and Biano Plateaux of 
Katanga. One of the females obtained by Dr. Pons in the Biano is before me. 
I am figuring the head in profile (Text Fig. No. 7) since the antennae of this 
species have never been properly described. The third segment was missing in 
Austen’s type; nor has it been described by Krober. The text figure 5 (on p. 214) 
of Kréber’s recent revision does not represent the head of C. neavei, but seems 
to be that of C. austent Neave. Moreover, C. neaver appears to be related to 
C. austeni and C. woodi Neave, although readily distinguished from either by the
