restricting the terms Bengal and Assam to the parts situated south of these 

 slopes. "Malacca" has so often been used to signify the whole of the Malay 

 Peninsula that it is unsafe to attach any more precise significance to it when dealing 

 with old records; "Malacca" has therefore been replaced by the term "Malay 

 Peninsula " here, a term used to include islands situated close to the mainland, such 

 as Singapore. 



Subfamily AULACOCYCLINAE. 



Members of this subfamily occur in China and Japan and throughout almost the 

 the whole of the Indo- Australian region ; but only one specimen has yet been recorded 

 from the Indian Peninsula, and none from Ceylon. 



Genus COMACUPES, Kaup, 1871. 

 = Aulacocyclus [part J, Kaup, 1868. 

 This genus occurs in the Malay Peninsula, Sunda Islands, Philippines and 

 Celebes. " Comacupes" felderi, Stoliczka (1873, p. 152) probably belongs to the 

 genus Tristorthus, so is omitted here.

 The hairless abdomen and practically unpunctured mesosternum suggest that 

 this species may be more closely alUed to the Australian genera Tristorthus and Aula- 

 cocyclus than to any member of the otherwise purely Oriental genus Comacupes. The 

 mentum is, however, more or less keeled in front, so I retain it in the last-named genus. 



In the ten specimens from Sarawak in the British Museum the central tubercle 

 is even less distinctly bifid than in the type of C. minor, Heller, from Celebes; so the 

 latter probably represents a distinct local race.
