SPECIES OF CULEX AND ALLIED GENERA. 249 
Austen (Entomologist, 1895, p. 228) overlooked the fact that the last joint of 
the hind tarsi is entirely white or whitish, while Theobald gives this as a 
character of C. puleripalpis (introducing C. pulcripalpis as British on some 
specimens which showed the character markedly) but not of C. dorsalis, As, 
however, every specimen in the British Museum, British or otherwise, whether 
determined as C. pulcripalpis or as C. dorsalis, has the last joint of the hind tarsi 
whitish, I feel fairly sure that the fact has simply been overlooked. There is in 
Britain, so far as the National Collection is concerned, only one species of the 
C. dorsalis group, and it seems & priori more probable that this would be Meigen’s 
species than Rondani’s. 
Mansonia arabica, Giles (J. Trop. Med. 1906, p. 130) is related to O. dorsalis, 
but can readily be distinguished by the much broader wing-scales, and there are 
other differences which show it to be distinct. Culea arabicus, Becker (Denkschr. 
k. Akad, Wiss. Math, Nat. kl. LXTX, 2, p. 140, 1910) is probably a homonym, 
as both appear to belong to the group Grabhamia.

5. O. longisquamosus, Theo. (Grabhamia), Ann. Mus. Nat. Hung. ITI, p. 102 
(1905). 
The ¢ and the hind ungues of the O of this species have not been described, 
but it seems to belong to ie O. dorsalis group, judging from the description. 
Tunis. 
6. O. pulcritarsis, Rond., Bull. Soc. Ent. Ital. IV, p. 31 (1872). 
Culex leucacanthus, Lw., Beschr. Eur. Dipt. ITI, p. 1 (1873). 
Culex mariae, Serg., These de Paris, p. 64 (1903). 
Grabhamia pulcritarsis, Theo., Mon. Cul. IIT, p. 244 (1903). 
The specimens of C. mariae in the British Museum agree perfectly with the 
descriptions of (. puleritarsis (by Ficalbi) and C. leucacanthus. The ungual 
formula in these specimens is ¢$ 2°1-2°l-0°0, Q 1:1-1'1-0°0, and not as given by 
Theobald in Mon. Cul. [V., p. 285; the above is the formula given by Ficalbi 
for O. puleritarsis. The species is quite distinet from C. dorsalis.

7. O. hirsutus, Theo. (Culex), Mon. Cul. I, p. 392 (1901). (Fig. 1.) 
Culex transvaalensis, Theo., Mon. Cul. ILI, p. 165 (1903), 
The proboscis has a broad though ill-defined band. Thisis quite a typical member 
of the Culicelsa group, taking C. taeniorhynchus, Wied, (nec Arrib.), as the type. 
S. Rhodesia ; Transvaal.
