8. 0. durbanensis, Theo., Mon. Cul. Ill, p. 246 (1903). 



Grahhamia durhanensis, Theo., I.e. 



„ ocellata, Theo., Mon, Cul. V, p. 284 (1910). 



The type of G. durhanensis is a small specimen, but evidently the same as 

 G. ocellata. 

 Natal ; Delagoa Bay. 



9. 0. nigeriensis, Theo. {Grahhamia), Mon. Cul. V, p. 281 (1916).' 



Rather closely resembles O. vigilax, Skuse, from Australia and 0. nocturnus, 

 Theo., from Fiji, but has much more numerous light scales on the wings. 



The (5 of C. vigilax has only a protuberance representing the tooth on the 

 larger claw of the mid tarsi ; the (^ of C. nigeriensis is not yet known. ' 



S.Nigeria; N.Nigeria; Uganda; Nyasa^land; 



10. 0- quasiunivittatus, Theo. (Culex), Mon. Cul. II, p. 32 (1901). 



Culiciomyia dalzieli, Theo., Mon. Cul. V, p. 234 (1910). 



An obscure species, and apparently rare, as only three specimens have been 

 received at the British Museum which can be referred with certainty to it : a 

 male and female from Salisbury, Mashonaland, and a female from Katagum. 

 N. Nigeria. It is not a Culiciomyia, and though differing considerably in 

 appearance from the three following species, must be included here on structural 

 characters. It could hardly be mistaken for C. univittatus, with which 

 Mr. Theobald has compared it. 



N.Nigeria; S. Ehodesia ; Natal; 



11.0. lateralis, Mg., Syst. Beschr. I, p. 5 (1818). 



Culicada lateralis, Theo., Mon. Cul. V, p. 310 (1910). 

 This European species has been recorded also from Algeria. It is very 

 distinct and unlike any other European or African species with the exception of 

 0. ornatus, Mg. 



12. 0. caliginosus, Graham {C2dex), Ann. Mag. Nat. Hist. (8) v, p. 2G8 (1910). 

 Resembles O. quasiunivittatus, but the hind ungues of the ? are toothed and 



the head-scaling is different. 



S. Nigeria. 



13. 0. ochraceus, Theo. {Culcx), Mon. Cul. II, p. 103 (1901). 



Culex palUdostriatus, Theo., Mon. Cul. IV, p. 410 (1907). 

 „ parascelos, Theo., Rec. Ind. Mus. IV, p. 18 (1910). 

 Mimetecidex hingii, Theo., Third Rep. Welle. Lab. p. 258 (1908). 

 This species can be very easily recognised by the general yellowish coloration, 

 legs striped with black and yellow, and the unequal hind ungues in the (^ . 

 Similar leg-markings are however to be found in Culex theileri ( ^ pettigreivii) ; 

 whilst in Pecnmyia and Eeedomyia lowisii the S d have unequal hind ungues. 

 I ckn see no difference between African and Indian specimens ; the species, 

 however, appears to be more common in Africa than in India. The unequal hind 

 ungues of the male do not seem to the writer to form a sufficient reason for 

 excluding the species from this genus. 



N. Nigeria ; Sudan ; S. Rhodesia ; India ; Cevlon.
