IN ORIENTAL CULIC1DAE. 233 



first fork-cell in the type has its base slightly nearer the apex of the wing 

 than that of the second. There are extremely slight colour differences between 

 Oriental, Australian and African specimens, but as T find that the male genitalia 

 are absolutely identical, I include C. annulirostris, C. somaliensis and C. sains as 

 synonyms without any doubt. C. ynophodes and C. microannulatus are also 

 evidently the same ; Theobald's statement that the single specimen of C. yno- 

 phodes " can at once be told [from C. microannulatus] by the relative positions 

 of the fork-cells and cross-veins, and by the abdominal banding and ornamenta- 

 tion " is quite erroneous, as there are certainly no such differences.

 The chief distinguishing characters of this species are as follows : small, light 

 brown in general appearance ; scales of mesonotum light brown, but not uniformly 

 so; femora and tibiae without any distinct intermingling of light and dark scales, 

 but the latter (especially the middle pair) have a more or less evident pale 

 lateral longitudinal stripe ; bases of fork-cells almost level, or that of the first 

 very slightly nearer the base of the wing than that of the second; male palpi 

 with a row of hairs as in C. sitiens. The male genitalia are quite distinct 

 from those of C. sitiens and also from those of C. tritaeniorhynchus, although 

 they much resemble the last-named. C. microtaeniata, C. pseudoinfula, and 

 C. parvus are included here as probable synonyms, as there is nothing in the 

 descriptions which will definitely separate them from C. vishnui. I have not 

 seen the types.

 This species, though very much like the preceding, can readily be distinguished 

 as follows : mesonotum clothed with dark brown scales, uniform in colour; scales of 

 femora and tibiae dark brown (except on under side of former), no intermingling 

 of light and dark scales, and no pale tibial stripe ; base of first fork-cell in female 

 distinctly nearer the base of the wing than that of the second, in the male the 

 bases are about level ; male palpi without the row of hairs found in the two 

 species just dealt with. Although the hind tarsi have only faint pale rings, there 

 is always some trace of these. The type ( Q ) of Giles' C. tritaeniorhynchus is in 

 the British Museum, and serves to explain why this inappropriate name was 

 given. Of the three bands on the proboscis described by Giles the one at the tip 

 is really formed by the pale labella ; the one near the base is merely due to some
