 (T. J. Anderson)^ 1 ,$ . Received through the Imperial 

 Bureau of Entomology. 



I have pleasure in naming this fine species after the donor 

 and captor, Mr. T. J. Anderson, Government Entomologist, 

 British East Africa. 



In general appearance this species strongly resembles 

 Anthi'dnim florentmum, Latr. The subgenus Meqanomia^ 

 Ckll. (Ann."& Mag. Nat. Hist. (8) iv. p. 402, 1909)1 hitherto 

 contained only one species, N. [Meganomia) hinghami, Ckll. 

 (/. c), of which both sexes are described from Damaraland. 

 The following differences seem to justify the description of 

 the East-African species as distinct : — 



N. {Meganomia) bhighami, Ckll. 



Tergites 2-6 with unbroken 

 yellow fasciae. 



Clypeus at apex i 1 . 



Flagellum not serrate. 



Hind trochanters pointed behind. 



Hind tibiae with a hump on 

 middle of inner side. 



N. {Meganomia) andersoni, sp. n. 



Tergites 2-6 with yellow fasciae 

 widely interrupted in middle. 

 Clypeus at apex |_J . 



Flagellum serrate. 

 Hind trochanters 7iot pointed 

 behind.

1-4 apice fasciis viridibus ; alis subhyalinis. 

 Long. 12-13 mm. 



Black, head and mesonotum rather densely clothed with a 

 mixture of fulvous and black hairs, sternnm and truncation 

 of median segment clothed with pale fulvous hair ; first 

 abdominal segment at base with conspicuous fulvous hair, the 

 following segments very scantily clothed with similar hair, 

 and some longer adpressed black hairs. The legs black, 

 scopa on hind legs mostly pale, but black on the outer side. 

 Wings subh valine, but with a distinct fuscous tinge. Abdo- 

 men shining black, segments 1-4 with apical green tegu- 

 mentary fascise of even width, the intensity of green varying 

 much in individual specimens.
