﻿AFRICAN CULICIDAE, OTHER THAN ANOPHELES. 31 



5. C. zeltneri, N.-L., Arch. Parasit. X, p. 251 (1906). 



This species seems to differ from C. thalassius in the ornamentation of the 

 mesothoracic integument. Judging from M. Neveu-Lemaire's figure, the median 

 pair of dark lines are less distinct and closer together, while the broader 

 lateral dark lines are concave outwardly, instead of convex as in most other 

 species of Culex. 



Abyssinia. 



6. 0. duttoni, Theo., Kept. Liverp. S. Trop. Med., Mem. V, App. p. v (1901). 

 Additional locality : Uganda. 



9. C. ataeniatus, Theo., U. South Afr. Dept. Agric, First Kept. Yet. Ees., 



p. 261 (1911). 



Described as "Proboscis dark at base and apex, dull ochraceous in the middle, 

 forming a broad pale band . . . abdomen brown with narrow basal pale 

 bands . . . legs brown, unhanded . . . Length 3 mm. ... A single 

 perfect female. At once told from all other Culex by the banded proboscis and 

 unbanded legs." I suspect this may be a variety of C. univittatus. 



Transvaal. 



10. C. argenteopunctatus, Ventr. (Heptaphlebomyia), Arch. Parasit. IX, 

 p. 446 (1905). 



This species is remarkably distinct from all other species of Culex known to 

 me on account of the four silvery spots on the mesonotum, recalling to some 

 extent Ochlerotatus punctotkoracis. In the present species, however, these spots, 

 and a broad silvery margin to the eyes, are composed of narrow curved scales ; 

 the scutellum also is clothed with similar scales. The general coloration is 

 greyish brown ; there is a distinct white spot at the apex of the hind tibia, and 

 basal lateral white spots on the abdominal segments. 



Dr. A. Ingram has bred 2 Q at Bole, Northern Territories,, Gold Coast. 

 Previously the species has only been recorded from Madagascar. 



12. C. tipuliformis, Theo., Mon. Cul. II, p. 325 (1901). 



This, I find, is an older name for the species previously dealt with as C. theileri, 

 Theo. Additional synonyms are C. creticus, Theo. (Mon. Cul. Ill, p. 189, 1903) 

 and C. onderstepoortensis, Theo. (U. South Afr. Dept. Agric, First Kept. Yet. 

 Ees., p. 265, 1911). I found the type of C. creticus in a pill-box on the lid of 

 which was written " Culex cretinus, n. sp.," but no locality. There is little doubt 

 that it is only a pale specimen of C. tipuliformis ; the leg-markings do not differ 

 in the way indicated in the description, nor, apparently, in any other way. C. 

 onderstepoortensis is described as " Related to Culex thcileri, but easily told by the 

 pale-scaled head and thorax." The scales of the head and thorax of the type 

 (in the British Museum) are not paler than in typical C. theileri. 



The cross-veins of this species are somewhat approximated, and on this 

 account Messrs. Dyar and Knab would place it in Culiscta (= Theobaldia) ; but 

 the male palpi are of typical Culex structure. 



Additional locality : British East Africa.
