2 SPECIES OF CULEX AND ALLIED GENERA. 263 
iii. C stoehri, Theo., Mon. Cul. LV, p. 419 (1907). The abdominal bands 
are more rounded, otherwise the specimen is like C. pallidocephala. 
Nyasaland. 
iv. C. varioannulatus, Theo., Mon. Cul. III, p. 198 (= C. azoriensis, Theo., 
; Mon. Cul. III, p. 210, 1903). This is an almost typical C. pipiens ; 
the females are rather shrivelled, hence the bands on the apical 
segments of the abdomen are not visible. 
Cape Colony ;: Azores. 
v. C. pipiens, L. 
N. Africa; Europe ; N. America. 
11. C. decens, Theo., Rept. Liverp. S. Trop. Med. Mem. IV, App. p. vii, 
(1901). 
C. masculus, Theo., Mon. Cul. II, p. 125 (1901). 
C. minutus, Theo., J. Econ. Biol. I, p. 30 (1905). 
C. nigrocostalis, Theo., Mon. Cul. V, p. 367 (1910). 
C. lividocostalis, Graham, Ann. Mag. Nat. Hist. (8) V, p. 269 (1910). 
Heptaphlebomyia simplex 3, Theo., Mon. Cul. IV, p. 533 (1907). 
Theobald states that in C. masculus the smaller claw on the fore and mid 
tarsi of the ¢ is not toothed; if this is the case (it is difficult to make out 
from the specimens), it is a very unusual variation. C. masculus seems otherwise 
identical with C. decens, which is a small and rather obscure species. Out of 
18 specimens in the National Collection only 2 are females. 
Sierra Leone; S. Nigeria; N. Nigeria; Sudan; Uganda; Transvaal. 
12. C. simpsoni, Theo., J. Econ. Biol. I, p. 28 (1905). 
Very much like C, decens, differing in the thoracic scaling. 
Transvaal. 
13. C. pruina, Theo., Rept, Liverp. S. Trop. Med. Mem. IV, App. p. viii, 
(1901). 
C. pruinosus, Theo., Mon. Cul. II, p. 332 (1901). 
C. pallidothoracis, Theo., Mon. Cul. V, p. 370 (1910). 
Easily distinguished from all other African species by the pale lateral areas 
on the thoracic integument. 
Ashanti ; S. Nigeria. 
14. C. ornatothoracis, Theo., Mon. Cul. V, p. 376 (1910), 
Very near C. grahami. Both have the female palpi longer than usual ; in this 
species they are quite one-fourth the length of the proboscis. 
S. Nigeria ; Gold Coast. 
15. C. guiarti, Blanchard, Les Moustiques, p. 629 (1905). 
C. viridis, Theo. (nec R.-D., 1827), Mon. Cul. III, p. 212 (1903). 
C. neavei, Theo., Second Rept. Welle. Lab. p. 76 (1906). 
The green colour is certainly not a specific character ; it not uncommonly 
occurs in many species, ¢.g., C. pipiens, C. grahami, C. pruina, Culiciomyia 
nebulosa, and the Tipulid Dicranomy/a chorea. 
Sudan ; Uganda; N. Nigeria; Gold Coast.
