Walker, List Neur. Brit. Mas., n, 475, no. 16, quotes this 

 species as Nemoptera angula Westw. I have never quoted Walk- 

 er's List except when the presence of types is stated ; which is 

 done with seven species. I have, too, not quoted Westwood's 

 monograph in Proc. Zool. Soc, 1841, part ix, 9-14, because it is 

 identical with the monograph in the Ann. Mag. Nat. Hist. ; I think 

 the latter was perhaps published some months later. 



I have before me male and female from Port Natal collected by 

 Drege ; the male from the collection Winthem has a label in King's 

 handwriting, " bacillaris " on the pin ; the female I bought from 

 the duplicata of Drege, in 1849 ; it has no. 1,535 on the pin ; this 

 number in the Catalogue of Drege's duplicata, published by Klug, 

 1841 (fasc. iv), is stated to be N. bacillaris Kl. Therefore, the 

 identity with Klug's species is certain ; besides I bought three 

 specimens more with the same number, which are N. latipennis 

 Br., which Klug does not seem to have separated from N. bacil- 

 laris. 



I have the strong opinion that the three species characterized by 

 Mr. West wood, 1835, in the Proc. of the Trans. Ent. Soc, are 

 from the same lot and the same collector. Drege's duplicata were 

 largely sold since 1835, and the catalogues (I have not the three 

 first numbers before me) stated that the insects were from west 

 Africa, and gave no names for a number of species, which were 

 later published. Finally, Westwood's three species are just the 

 same as I find represented among the duplicata, to wit, angulata 

 (:= bacillaris), of which is stated in brackets " an mas praece- 

 dentis?," costalis, which is very probably the female, and Africana 

 (= latipennis) . Perhaps Prof. Westwood will be able to decide 

 whether I am right or not. 



Male, long, corp., 20mm. ; long. al. ant., 29mm. ; long. al. 

 post., 66mm. Head above light reddish brown, before the an- 

 tennae and below yellow, with a brown ring just before the an- 

 tennae ; the large eyes are scarcely more distant than its diameter ;
