SPECIES OF CULEX AND ALLIED GENERA. 251 
14. O. leucarthrius, Speiser (Culex), Kilimandjaro-Meru Exp., 1905-6, Dipt. 
Orth., p. 43 (1909). 
Dr, Sjostedt very kindly lent me the type of this species, and I can add the 
following notes to Dr. Speiser’s description : 
Head, bearing golden-yellow narrow-curved scales in the middle. 
Thorax black, with brown seales, a short line of golden scales on the lateral 
margin in front, and a similar short line on each side of the middle line in 
front of the scutellum. Scutellum covered with narrow-curved bright 
golden-yellow scales ; bristles golden. 
Abdomen blackish, the segments with small lateral pale basal spots. 
The hind ungues are missing, but it seems to be an Ochlerotatus ; it is quite 
distinct from anything I have seen. The golden-scaled scutellum and the 
distinet pale band on the apex of the hind tibiae distinguish it at once. 
German East Africa. 
Genus THEOBALDIA, Neveu-Lemaire. 
C. R. Soc. Biol., 1902, p. 1331. 
Culiseta, Felt, New York State Mus. Bull. 79, p. 391e (1904). 
This seems to be a well-marked genus. The claws and antennae are as in 
Culex, but the male palpi have the last two joints swollen, the terminal porrect 
and longer than the penultimate, being thus somewhat intermediate in structure 
between Culex and Ochlerotatus. The genus includes, besides the species 
mentioned in Theobald’s monograph, Culiseta absobrina, Felt, and Culicada 
morsitans, Theo. The spotting of the wings, as might be expected, is not a 
constant generic character. Two species have been recorded from Africa.

» without white lines ae aa an ang ti annulata, 
1. T. spathipalpis, Rond., Bull. Soc. Ent. Ital. IV, p. 31 (1872). 
Very variable in size, but easily recognised by the white lines on the thorax 
and the banded and spotted legs, which have a whitish ring just before the tip of 
the femora. The spots on the legs recall Culex tigripes. but the two can hardly be 
confused.

2. T. annulata, Schrank, Beit. z. Naturg. 97, 70 (1776). 
Algeria. 
Genus TAENIORHYNCHUS, Arrib. 
Rev. Mus. La Plata, II, p. 147 (1891). 
Mansonia, Blanchard, C.R. Soc. Biol. 53, p. 1046 (1901), 
This genus is accepted in its original signification, the principal character 
separating it from other allied genera being the peculiar formation of the ungues 
(3d 2°0-2°0-0°0 or 1:0-1:0-0°0, Q 0:0-0:0-0°0). The wing-scales vary greatly in 
width from the very broad ones in the type 7’. trtillans, Wik. (=taeniorhynchus, 
Arrib., nec Wied.) to the narrow ones of 7. aurites and its allies. The author 
fully agrees with Messrs. Dyar and Knab (Ent. News, July, 1910) that the genus 
Mansonia was a composite one, the Old World species belonging to a distinct 
genus, while 7. titillans, T. fasciolatus, etc., are congeneric with the species 
erroneously added by Theobald to Goeldi’s genus Chrysoconops ; it also
