SlPEClES OF CULEX AND ALLIED GENERA. 253 



lias been wrongly recorded from the Malay States ; the specimens are T. ochraceus, 

 which differs from 7'. auritcs in having no median black ring on the hind tibiae.

Chrysoconops pseudoconopas, Theo., Mon. Cul. V., p. 443 (1910). 

 The specimens of C. pscudoconopas have the thorax very much rubbed, but I 

 can see no difference between them and the types of C. annettii. All the specimens 

 I have seen of C. annettii have the distinguishing characters given by Theobald 

 for C. pseudoconopas. The dark scales on the wings occur chiefly in two tranverse 

 bands, one before the tip of the wing and including the bases of the fork-cells, 

 the other nearer the base. These bands are more conspicuous in some specimens 

 than in others.

Culex drymoecivs, Speiser, Kilimandjaro-Meru Exp., Dipt. Orth. p. 42 (1909). 

 Dr. Sjostedt very kindly lent me a specimen of C. drymoecius, and it proved to 

 be quite a typical T. fuscopennatus, though it certainly did not show the black 

 abdominal spots mentioned by Dr. Speiser in his description. As, however, one 

 or two males in the British Museum collection show these spots rather indis- 

 tinctly, I think C. drymoecius can only be a variety of T. fuscopennatus.

Genus Mansonioides, Theo. 

 Mon. Cul. IV., p. 498 (1907). 



Mansonia, Blanchard, C. R. Soc. Biol., LIII, p. 1046 (1901) (part). 

 As suggested by Messrs. Dyar and Knab, and noted above, the Old-World 

 species of " Mansonia " cannot be kept in Taeniorhyuchus. They resemble that 

 genus in the peculiar structure of the claws, but the male palpi are so different 

 that they are obviously distinct. The penultimate joint is thin and curved 

 upwards, as in Culex, but the terminal joint is very short — |- to \ as long as the 

 penultimate, and bent downwards at an angle with it. The terminal joint, in all 

 the males I have seen {M. uniformis, M. annuUpes and M. annulifera) is entirely 

 covered with white scales. The resemblance in all structural details, and in 

 many minor characters as well, between M. annulifera and M. uniformis is so 

 great that I do not think it is possible, in this case at least, to regard the presence 

 of flat or narrow-curved scales on the scutellum as a generic character. Probably 

 Etorleptiomyia is a synonym, but as the male of E. mediolineata is unknown, I 

 have adopted the later name Mansonioides for this genus.
