61. Phytomia (Megaspis) bullata, Loew (1858). 



An entirely black species, very distinct owing to the numerous 

 black abdominal bulke and the extended black pattern of the 

 wings. 



This characteristic species, which is not unlike the Tabanid 

 Tfiaumastocera akicct, Griinbg., was originally described from 

 Caffraria, and subsequently recorded from Kihmandjaro by Dr. 

 Speiser. Loew compares the species with Ph. crassa, Fabr., in 

 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. 



Two females from British East Africa, one from Mt. Kenia, 

 W. side, Meru-Xyeri Road, 6,500 ft., 22. ii. 1911, and the other 

 fromS.E. slopes of Kenia, 6,000-7,000 ft., 3-12. ii. 1911 (S. A. 

 Neave).
