 Culex pseudoannulioris, Theo., Men. Cul. V, p. 333 (1910), 

 Taeniorhynchus tenax, Theo., Mon. Cul. Ill, p. 258 (part). 

 This is very closely allied to C. quasigelidus, and may perhaps be only a 

 variety of that species ; the difference in the leg marking, however, is so very 

 striking that I prefer to consider them distinct. The four specimens of C. pseudo~ 

 annulioris in the British Mviseum collection are all rubbed ixknost bare (they must 

 have been described in that state), but I believe they can be safely included 

 ..tiBder C. consimilis. This species is no doubt the African representative of the 

 Oriental C. ager, but it is difficult to accept Mr. Theobald's opinion that the two 

 forms are conspecific ; the true C. ager (= Taeniorhynclms tenax) is not African. 

 Of the Oriental species there are two varieties : —

 Grahhamia taeniarostris, Theo., Mon. Cul. IV, p. 29.9 (1907). 

 The var. sinensis is distinguished from the type form by the presence of basal 

 as well as apical yellow bands on the abdominal segments. ' . 



In Mr. Newstead's series of C. consimilis are specimens of the preceding 

 species, but the type has no spots on the legs.

3. C. annulioris, Theo., Liverp. S. Trop. Med., Mem. V, App. (1901). 



This species is really very distinct, but has been confused with C. duttoni, one 

 of the types ((5) of C. hirsutipalpis (^ duttoni) actually being a specimen of 

 C. annulioris. The markings of the thorax and abdomen, and the absence of the 

 stripe on the tibias, will suffice to distinguish the present species from C. duttoni.

 The pale stripe on the tibise of this species is sometimes rather obscure, but in 

 conjunction with the broad band on the proboscis, the two pale spots on the
