posterior to the anterior transverse groove ; strongly and rather

 elytron.

Head, prothorax, and body underneath, black ; elytra purplish- or 

 violaceous-black in the basal half, testaceous or yellowish in the 

 hinder half, with the testaceous colour extending forwards triangularly 

 at the suture ; antennae testaceous or fulvous, with the last few 

 joints slightly infuscate ; femora blackish, tarsi, and the tibiae to a 

 greater or less extent, testaceous. Head and prothorax sparsely 

 punctured, the punctures being thickest and most distinct around the 

 central tubercle of the pronotum. Elytra sparsely and rather feebly 

 punctured. 



Hob. Malacca, Singapore, Johore, and Sinkip Island. 

 Type in Brit. Mus. 



In the type from Singapore, the elytra are slightly- 

 tinted with purplish at the apex, and in the specimen from 

 Johore they are distinctly but very narrowly tipped with 

 violet. The species is very nearly allied to A. partita 

 (= daldorfii, Fab.), but is somewhat smaller in size, and 

 distinguishable by the much greater extent of the 

 violaceous area on the basal half of the elytra.

 extent from each shoulder, violaceous-blue ; antenme reddish-brown 

 at the base, fuscous at the end, the intermediate joints being pale 

 testaceous ; body underneath black ; legs piceous with the tarsi and 

 sometimes also the apices of the tibiae testaceous.
