9. NODA VIOLACEIPENNIS, S[). nOV. 



Oblong-ovate, blackish green below, violaceous blue above ; thorax 

 moderately punctured, elytra semi-punctate-striate, without costae. 

 Legs and antenna? greenish aeneous. 



Length 2 lines. 



Head and clypeus with some widely dispersed deep punctures, 

 the former besides with an obsolete fovea in the middle ; antennae 

 more than half tbe length of the body, robust, uniformly greenish 

 aeneous, with the exception of the two basal joints, which are stained 

 with piceous. Thorax of the same shape as the other species of this 

 paper, but rather finely punctured, the punctures on the disk 

 assuming an oblong shape here and there, while the punctuation 

 near the lateral margins is very obsolete. Elytra more oblong than 

 in the other species, shining violaceous blue, with the punctures 

 stronger than those of the thorax, and rather confusedly placed, only 

 towards the apex more distinctly geminate-punctate-striate ; the 

 intervals not raised, only an obtuse tubercle visible near the extreme 

 apex; the suture on each side accompanied by an impressed line, 

 commencing about the middle of the elytra, to the apex. Underside 

 and legs greenish black. Tarsi and claws obscure piceous.

 thorax, rather finely punctate-striate, the interstices broadly costate
