and rather closely punctured. Scutellum not longer than broad. 

 Elytra much broader at the base than the thorax , elongate and 

 parallel, shining metallic green, with a narrow but very di- 

 stinct transverse depression below the base ; within this depres- 

 sion the punctures are more strongly impressed than at the 

 rest of the surface which is rather finely punctate-striato , the 

 punctuation getting nearly obsolete near the apex ; the suture 

 is slightly raised along its entire distance. Legs slender and 

 elongate, the femora generally of a brownish piceous colour 

 and without teeth. 



New Guinea, Ramoi (L. M. D'Albertis). 



The narrow elongate shape of this insect, its nearly square- 

 shaped and finely punctured thorax, in connection with the 

 episteme which is not separated from the face and the bright 

 metallic green upper surface will distinguish it from the other 

 described metallic species. 



29. Rliypai'itla, didyma, Fabr. 



Of this species, which is to be found in most collections, a re- 

 markable variety is contained in my own and has also been 

 obtained , together with the typical form by M.»" L. M. D'Al- 

 bertis in Somerset (Cape York), Australia. 



In this variety of which 7 specimens are before me and which 

 I propose to name : 



Rlxypai'ida, didyina var. FulT^oplag-iata. 



The elytra are entirely black with tlic exception of the la- 

 teral margin at the base and two elongate fulvous spots placed 

 close to the suture behind the middle. In all other characters 

 the variety agrees with the type from which it is absolutely 

 nut to be separated in any way.
