Genus AULACOCYCLUS, Kaup (1868) 1871. 

 = Aulacocyclus [part], Kaup, 1868; incl. Taeniocerus [part] Kaup, 1871. 



I have not attempted to do more than accept the opinions of previous authors 

 in the following list of the species of this genus. Blackburn (1896, p. 234) has 

 already pointed out the difficulty of dealing with it. He suggests that several of the 

 names accepted below are really synonymous. I am inclined to agree with him ; but 

 I cannot help thinking, in addition, that the characters to which he has been driven 

 to attach the greatest taxonomic importance, are likely to prove to have been 

 misleading, when a larger number of specimens are compared together. 



The genus is centred in the parts of the Indo- Australian Region east of Wallace's 

 Line, but occurs in the Philippines and Sunda Islands also. Only one specimen has 

 yet been found on the mainland of Asia; it is from the Indian Peninsula.
