SPECIES OF CULKX AND ALLIED OENEEA. 263 



iii. C stoehri, Theo., Mon. Cul. IV, p. 419 (1907). The abdominal bands 



are more rounded, otherwise the specimen is lilte C. pallidocephala. 

 Nyasaland. 

 iv. C. varioannulatus, Theo., Mon. Cul. Ill, p. 198 (= C. azoriensis, Theo., 



Mon. Cul. Ill, p. 210, 1903). This is an almost typical C. pipicns ; 



the females are rather shrivelled, hence the bands on the apical 



segments of the abdomen are not visible. 

 Cape Colony ; Azores. 

 T. C. pipiens, L. 



N. Africa ; Europe ; N. America. 



11. C. decens, Theo., Kept.* Liverp. S. Tfop. 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 S , Theo., Mon. Cul. IV, p. 533 (1907). 

 Theobald states that in C. masculus the smaller claw on the fore and mid 

 tarsi of the (^ ia 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,

13. C- pruinaj Theo., Rept, Liverp. S. Trop. Med. Mem. IV, App. p. viii, 



(1901). 

 C. pruinosus, Theo., Mon. Cul. II, p. 332 (1901). 

 C. pallidotlwracis, 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. oriiatothoracis, 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. {nee R.-D., 1827), Mon. Cul. Ill, p. 212 (1903). 

 C. neavei, Theo., Second Eept. Welle. Lab. p. 76 (1906). 

 The green colour is certainly not a specific character ; it not uncommonly 

 occurs in many species, e.g., C. pipiens, C. grahami, C. pruina, Culiciomyia 

 nebuiosn, and the Tipulid Dicranomyia chorea, 

 Sudan ; Uganda ; N. Nigeria ; Gold Coast,
