Veiy cluscly allied to tliese three forms of nigricans is tlie 

 Austialian N. rdiaria, Turn., in wiiicli the punctures o£ tlie 

 mesoiiotum are ahnost obsolete and the eyes nearer to eacli 

 other on the vertex. I do not consider that small diflferences 

 in the comparative length of the abscissa3 of the radius are to 

 be relied on in this genus; there seems to be a slight indi- 

 vidual variation in this respect. N. mahensis. Cam., from 

 the Seychelles, ditTers from reticulata in the longer and rather 

 narrower radial cell. 



Notogonia irromta, Sm.

 Mutes liriuides, Turn. Trans. Ent. Soc. London, p. 753 (1912). $. 



Although the tarsal ungues are toothed in this s{)ecies in 

 the female, the veiy diiTerent form of the pygidial area shows 

 tha^ it is not closely related to Motes. 



Hah. East Africa from ]\lashonaland to Witu ; West 

 Aiiiea, Gambia and Gold Coast. 



Doubtless this species ranges througli the whole of tropical 

 Africa. 



Nologonia deceptor, Turn. 

 Motes deceptor, Tm-n. Ann. & Mag-. Nat. Hist. (8) xvii. p. 253 (1916). 



Tliis is closely related to N. crossus, and is not a Motes. 

 It n)ay possibly prove to be a colour-variety of crcesus, the 

 structural ditferences being very slight.
