(where the water has splashed over) round the wells and 
water casks at the tanks. Walker records #. punetofer 
from Tajurra.” 
I believe that Col. Yerbury has correctly identified this

10. Simoides crassupes. 
“ Hristalis crassipes, Fabr., Syst. Antl., p. 237, 22. 
Simoides crassipes, Loew, Dipt. Sud.-Afr., p. 322. 
Only one specimen taken at Lahej, 7.3.95. This 
species was seen flying round the flowers of Terminalia 
catappa in company with the bee Apis indica; it was 
extremely difficult to distinguish the two insects apart 
when on the wing.” 
This case of mimicry is very interesting.
