Upolu I. : Apia, June to Sept. (Swale). 



A specimen of eacb sex was taken by 

 Dr. Swale. Although agreeing with A. upo- 

 luensis in its rather oval outline and convex 

 form, as well as in. the broadly rounded hind 

 angles of the thorax and parallel-sided elytra, 

 it has many well-marked points of difference. 

 The mandibles are flattened and curve strongly upwards, and, instead of an upper 

 and lower tooth, one above the other, near the base, have a single strong 

 blunt lobe at the same point ; the ocular lobe forms a strong projection on 

 each side of the head ; the front angles of the thorax are scarcely produced, 

 the elytra are still shorter, only very lightly striate, the first stria breaking up 

 into irregular points and the 5th and 7th only feebly indicated, the interstices 

 are very finely and closely punctured (a little more strongly, but still finely, at 

 the sides and apices), the prosternum is narrowed between the coxae and 

 rather carinate behind them and strongly punctured. The middle legs are 

 closer together, the metasternum scarcely produced between them, the sides 

 less strongly punctured, the punctures not Hnear in shape and not extending 

 to the base. The round depression at the middle of the base is not well 

 defined. The front tibiae are broader and bear stouter external teeth. 



The male (type) specimen is no doubt a small representative of the species,
