JJab. Batjan (W. Doherty) ; 2 cJcJ. 



Though in general appearance closely resembling A. viduata from tlie larger 

 Snnda Islands, this species is more nearly related to A. immaculata (Nov. Zool. 

 1894, p. 033) from New Guinea in the ronnded carina of the prothotax, in the 

 presence of a postmedian tubercle on each elytron, and in the deeper median 

 impression of the rostrum ; but is easily distinguished from immuculata by the 

 much less raised basal gibbosity of the elytra and the much feebler and more elongate 

 postmedian tubercle.
