92 ME. r. SMITH ON NEW SPECIES 



very bright blue-greea, changing in different lights; beneath rufo- 

 testaceous. 

 Hob. Morty Island. 



This insect so closely resembles the N. concinna from Celebes 

 and Ceram, that I suspect it may be the true male of that species ; 

 that which I have described as being so is probably a distinct 

 species.
