﻿20 F. W. EDWARDS — A SYNOPSIS OF THE SPECIES OF 



10. 0. hirsutus, Theo., Mon. Cul. I, p. 392 (1901). 



Additional localities : British East Africa (Kitui, 7. vi. 1911, T. J. Anderson); 

 Uganda (Busoga, Dr. Hodges) ; Gold Coast (one small female). 



12. 0. nigeriensis, Theo., Mon. Cul. Y, p. 281 (1910). 



Culicelsa fryeri, Theo., Trans. Linn. Soc. Lond., XY, 1, p. 84 (1912). 

 Additional locality : Bole, Gold Coast {Dr. A. Ingram) ; good series of both 

 sexes bred from larvae. 



12a. 0. sudanensis, Theo. {Culex), Fourth Eept. Welle. Lab. Vol. B, p. 154 



. (19U > 

 This is evidently closely allied to O. nigeriensis, though the author does not 



compare it with that species, since he places it in Culex. He does not say 



whether there are any white scales on the wings, and so it may not be correctly 



placed in the table. Apparently it is distinct from 0. nigeriensis, since the thorax 



is described as " tesellated with golden brown and deep brown, showing traces of 



linear arrangement." In O. sudanensis the proboscis is said to be unhanded, in 



O. nigeriensis it is pale in the middle beneath and at the sides. 



Sudan. 



12b. 0. caballus, Theo., Entomologist, XLY, p. 93 (1912). 

 Grahhamia caballa, Theo., I.e. 



" Q . Head and thorax with rich deep golden scales, a dark patch on each side 

 of the head. Thorax showing traces of linear markings, and with golden chaetae. 

 Palpi and proboscis deep brown : antennae brown. Abdomen deep brown, with 

 basal creamy bands which spread out to form large lateral spots, and also send 

 out median processes which in some specimens form a dorsal line. Legs brown, 

 mottled with creamy scales, and with prominent basal pale bands ; ungues all 

 equal and uniserrate. Wings with brown and creamy scales. Length 4 to 

 5 mm. 



" Habitat. — Onderstepoort, Transvaal. 



" Observations. — Described from twelve females. It comes near G. durbanensis, 

 Theob., but can be told by the hind ungues being uniserrate." 



13. 0. arg'enteopunctatus, Theo. {Stegomyia), Mon. Cul. I, 316 (1901). 



This and the two following species, again, form a very closely allied group, and 

 it may be doubted whether or not the three forms are really distinct : there 

 appear to be no other constant differences than those given, though there is 

 considerable variability. 



Sudan ; N. Nigeria ; Uganda ; S. Rhodesia. 



14. 0. domesticus, Theo. {Uranotaenia), Mon. Cul. II, p. 253 (1901). 



Aedimorphus domesticus, Theo., Mon. Cul. Ill, p. 291 (1903). 

 S. Nigeria ; Ashanti ; Uganda. 



15. 0. punctothoracis, Theo. {Aedimorphus), Ann. Mag. Nat. Hist. (8) V, 



p. 374 (1910). 

 Aedimorphus punctithor ax, Theo., Mon. Cul. Y, p. 205 (1910). 

 It should be mentioned here that the figure given by Theobald (Mon. Y, p. 206) 

 to represent the male genitalia of this species, in reality refers to 0. albocephalus.
