StECIES OF CULEX AND ALLIED GENERA. 251

 Orth., p. 43 (1909). 

 T>T. 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 scales, 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 a Ochlerotatiis ; it is quite 

 distinct from anything I have seen. The golden-scaled scutellum and the 

 distinct pale band on the apex of the hind tibiae distinguish it at once. 

 German East Africa. 



Genus Theobaldia, Neveu-Lemaire, 



C. E. Soc. Biol., 1902, p. 1331. 



Culiseta, Felt, New York State Mus. Bull. 79, p. 391c (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. 



Thorax with narrow white lines ... ... ... ... ... spathipalpis, 



„ without white lines ... ... ... ... ... annulata. 



1. T. spathipalpis, Eond., 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.

 This genus is accepted in its original signification, the principal character 

 separating it from other allied genera being the peculiar formation of the ungues 

 (d" 2-0-2-0-0-0 or I'O-l-O-O-O, Q O-O-O-O-O'O). The wing-scales vary greatly in 

 width from the very broad ones in the type T. titillans, Wlk. (:=taeuiorhi/nchus, 

 Arrib., nee Wied.) to the narj-ow ones of T. 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 T. titillans, T. fasciolatus, etc., are congeneric with the species 

 erroneously added by Theobald to Goeldi's genus Chri/soconops ; it a!so
