236 Records of the Indian Museum. [Voiv. VI, 



If this latter is the case, then the genus Cfenophora does not 

 occur in the Bast at all. Ctenophora is in fact confined to 

 Europe, Siberia and North iVmerica, with the exception of a single 

 species from Persia ; whilst Pselliophora is confined to the eastern 

 tropics, also with one exception, fumiplena, Wlk., from China. 

 This species even might have been regarded as doubtful but that 

 Osten Sacken has examined the type, at the British Museum, 

 where some other specimens also from China appeared to him to 

 be a variety of the species. 



The other recorded species, C. melanura^ Wlk. (List Dipt. Brit. 

 Mus,, i, 78), is not even a Tipulid at all, but is a large Sargus 

 (Stratiom^ddae), as stated by Osten Sacken, after an examination 

 of the type in the British Museum. 



It is true, however, that there is yet one species recorded as 

 Ctenophora of which the locality is unknown (C constans, Wlk., 

 Ins. Saund. Dipt., 448, 9 ), but the probability is that it is not 

 Oriental.
