Waterhouse, and in his determination table for the Pachyrrhyn- 

 chus species describes it as follows : 6 



From this it is clear that he also was mistaken with respect 

 to this species. In 1918, on the strength of the determination 

 of Professor Heller, I published some biological notes on the 

 false Pachyrrhynchus venustus, 7 and in 1922 I figured the penis 

 structure, 8 also under the wrong name. The following remarks 

 will serve to clear up matters concerning the above species of 

 Pachyrrhynchus : 



Pachyrrhynchus venustus Waterhouse.

 This species is shiny black and the elytra are impunctate. 

 The scale spots are reddish or coppery golden metallic, and in 

 fresh specimens are strongly opalescent. The spots laterad on 

 the prothorax are roundish, not oblong-oval. The number of 

 spots on the elytra is variable, as in the other related species.

 This subspecies is uniform black and is known only from Siar- 

 gao and Bucas Grande Islands.
