Ilab. New Guinea , Mom , December (0. Beccari). 



The specimens obtained l)y M.^ Beccari differ slightly from 

 the type which I have for comparison. (In M.^" Baly's collection 

 the latter is named P. celebensis, but this must be a mistake as 

 no species of this name has been published to my knowledge 

 and the description of P. malcujana agrees perfectly with the 

 species). The New Guinea specimens are of a more violaceous 

 blue colour , the antennae are testaceous with the terminal joints 

 obscure fuscous and the punctuation of the thorax and the elytra 

 is rather more rugose; in the absence of other characters I prefer 

 to consider these specimens as varieties rather than a new spe- 

 cies , as they agree in shape and all other particulars.

Testaceous; terminal joints of the antennae, posterior femora, 

 labrum and palpi piceous; thorax and elytra impunctate.

 ture narrowly fuscous; surface nearly impunctate or microsco- 

 pically finely punctured, posterior femora piceous; metatarsus of 

 the hinder tibiae as long as the two following joints together.
