61. Phytomia (Megaspis) bullata, Loew (1858). 
An entirely black species, very distinct owing to the numerous 
black abdominal bulle and the extended black pattern of the 
wine's. 
Yhis characteristic species, which is not unlike the Tabanid 
Thaumastocera akwa, Gyriinbg., was originally described from 
Caffraria, and subsequently reed from Kilimandjaro by Dr. 
Speiser. Loew compares the species with Ph. crassa, Fabr., m 
which, however, the legs are very different ; especially as regards 
the coloration of the legs, there is greater resemblance to the 
Oriental Ph. chrysopyga, Wied. Speiser, in 1910, recorded the 
male, which was previously unknown, but did not describe it. 
''wo females from British East Africa, one from Mt. Kenia, 
W. side, Meru-Nyeri Road, 6,500 ft., 22. ii. 1911, and the other
