﻿AFRICAN CULICIDAE, OTHER THAN ANOPHELES. 21 



The slide no doubt was wrongly labelled. Very abundant at Accra. One of 

 the two females labelled " Stegomyia argenteopvnctata, type" by Theobald is this 

 species. 



Gold Coast ; Angola ; S. Rhodesia. 



16. 0. ornatus, Mg., Syst. Bes. I, p. 5 (1818). 



The specimen recorded by Theobald (Mon. Cul. Ill, p. 191) as Culex lateralis, 

 Mg., is, I find, not that species, but closely related to it and probably referable 

 to O. ornatus. When I included O. lateralis as African in my table (Bull. Ent. 

 Res. Oct. 1911, pp. 248, 250), I had not examined the specimen. O. ornatus has 

 complete pale bands on the abdomen, whereas 0. lateralis has only lateral pale 

 spots at the base of each segment. In the Algerian specimen referred to and in 

 another from Fez, Morocco (May 1909, Major C. E. P. Fowler), the scutellum 

 bears mostly flat white scales (the Algerian specimen is considerably denuded). 

 As these are the only two specimens of O. ornatus which I have seen, I cannot 

 say whether the flat-scaled scutellum is normal or not. Ficalbi attributes the 

 name C. ornatus, Mg. to another species. 



17. 0. alboventralis, Theo. (Protomacleaya), Mon. Cul. V, p. 251. 

 Angola. 



18. 0. africanus, Newstead (Duttonia), Ann. Trop. Med. 1, p. 20 (1907). 



The name africanus is retained for the present, but if Ochlerotatus and Stego- 

 myia be merged, it will be preoccupied by S. africana, Theo., similarly if 

 Taeniorhynchus africanus, Neveu-Lemaire be shown to be an Ochlerotatus, a new 

 name will have to be proposed for Newstead's species. 



O. africanus was described from a single female, and its validity as a species is 

 somewhat doubtful. It seems, however, to be distinct by the character given in 

 the key. The thorax is rubbed, but the scales appear to be all dark. 



Congo. 



19. 0. albocephalus, Theo. (Stegomyia), Mon. Cul. Ill, p. 140 (1903). 

 Polyleptiomyia albocephala, Theo., Gen. Ins. Culicidae, p. 21 (1905). 



This species is only known to me in the male sex. It is possible that its female 

 may have been included under O. minutus, but if so I do not see how to distin- 

 guish them. The male genitalia are very peculiar and have been figured by 

 Theobald as those of O. punctothoracis (Mon. Cul. V, p. 206, fig. 79). Of the 

 mosquitos whose genitalia 1 have seen, O. cumminsi alone exhibits a somewhat 

 similar structure in these organs. 



Gambia ; Gold Coast.
