* The Cicadida: of Celebes have still to be collected, for though the islands have been visited by several excellent 

 naturalists, the msects described in this monograph have not greatly engaged their attention. That they exist in numbers 

 may be gatliered from the remark of Dr. A. Adams, that " In the forests of Celebes" is heard '"the eternal ringing song of 

 the shrill Cicada."— (' Notes on Nat. Hist. ; Voy. H.M.S. Samarang,' vol. ii. p. 2C8). 



" The Central Continent of the island has not yet seen the face of the white man, and by far the greater part of the 

 tour peninsulas is almost unknown and undescribed ; in fact, the only parts which are thoroughly explored and utilised by 

 iLuropeans are not much larger in area than the Isle of Wight and the Isle of Man."— (Sydney J. Hickson, ' A Naturalist in 

 North Celebes,' p. 3). ^ J J
