from that from Dorey in being relatively considerably shorter ; the 

 discoidal thoracic areolet is extremely narrow ; the elytra have the 

 lines of punctures rather stronger, and the punctures are more 

 transverse. This specimen may prove to belong to a distinct 

 species. 



Metriorrhynchus nobilis.

Hab. New Guinea ( Wallace). 



Thorax rather small, the mesial areolet nearly extending to the 

 anterior margin, moderately broad before the middle. Elytra with 

 the eight costse very distinct, the alternate ones less elevated in the 

 middle of the elytra, but equally distinct at the base ; the interstices 

 have each a single line of close, strong punctures. The yellow at 

 the apex of the elytra extends for rather more than one third of 

 their length. 



At some little distance from the apex the fifth and seventh fine 

 costae are united to the sixth ; and the fifth and sixth, and the 

 seventh and eighth lines of punctures become united, the punctures 

 then being transverse. I believe these abbreviated costae to be a 

 malformation ; but the two elytra being exactly similar, it may be 

 normal. 



Metriorrhynchus vagans. 



(Plate XIII. fig. 10.) 



Ater ; thorace rufo-flavo, septemareolato ; elytris octocostatis, in- 

 terstitiis biseriatim crebre fortiter punctatis, seriebus linea tenui 

 divisis. 5 . Long. 5 lin. 



Hah. Sumatra. 



A much shorter species than any of the preceding, with very 

 coarsely punctured interstices to the elytra. The thorax has the 

 seven areolets very distinct, the posterior angles are acute and slightly 

 diverging. 



This species closely resembles Bulenides turhiclns (before de- 

 scribed), but differs in the form of the thorax, which has also 

 seven areolets instead of a single narrower discoidal one.
