8. QO. durbanensis, Theo., Mon. Cul. TIT, p. 246 (1903). 
Grabhamia durbanensis, Theo., /.c. 
f ocellata, 'Theo., Mon. Cul, V, p. 284 (1910). 
The type of G. durbanensis is a small specimen, but evidently the same as 
G. ocellata. 
Natal; Delagoa Bay. 
9. O. nigeriensis, Theo. (Grabhamia), Mon. Cul. V, p. 281 (1910). 
Rather closely resembles O. vigilax, Skuse, from Australia and O. nocturnus, 
Theo., from Fiji, but has much more numerous light scales on the wings. 
The 3 of C. viyilax has only a protuberance representing the tooth on the 
larger claw of the mid tarsi; the ¢$ of C. nigeriens’s is not yet known. 
S. Nigeria; N. Nigeria; Uganda; Nyasaland. 
10. O. quasiunivittatus, Theo. (Culex), Mon. Cul. IT, 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. wnivittatus, with which 
Mr. Theobald has compared it. 
N. Nigeria; S. Rhodesia; Natal. 
11. O. 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 
distinet and unlike any other European or African species with the exception of 
O. ornatus, Me. 
12. O. caliginosus, Graham (Culex), Ann. Mag. Nat. Hist. (8) v, p. 268 (1910). 
Resembles O. guasiunivittatus, but the hind ungues of the 2 are toothed and 
the head-scaling is different. 
S. Nigeria. 
13. O. ochraceus, Theo. (Culex), Mon. Cul. II, p. 103 (1901). 
Culex pallidostriatus, Theo., Mon, Cul. IV, p. 410 (1907). 
5, parascelos, Theo., Rec. Ind. Mus. IV, p. 18 (1910). 
Mimeteculex 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 theiler? ( = pettigrewit) ; 
whilst in Pecomyia and Reedomyia lowisii the $ S have unequal hind ungues. 
I can see no difference between African ard 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; 8. Rhodesia ; India ; Ceylon.
