252 Phytophaga Malay ana. 



anterior border bounded within by a deep transverse groove ; 

 surface of disk remotely punctured, punctures more crowded and 

 somewhat coarser on the sides. Scutellum thickened, subpen- 

 tagonal. Elytra much broader than the thorax, broadly oblong, 

 convex, lateral border narrowly dilated, excavated below the 

 basilar space, the latter slightly thickened ; longitudinally sulcate 

 within the humeral callus, the callus itself prominent ; striae entire, 

 finely punctured, impressed with larger deeper punctures on the 

 anterior disk below the shoulders ; interspaces plane. 



Very similar in colour to N. evanescens (ante, p. 243), but the 

 thorax is much less strongly punctured, and entirely metallic- 

 green.

 shaped, its surface coarsely punctured, its anterior border slightly 

 concave ; antennae slender, filiform, nearly equal to the body in 

 length, four lower joints fulvous, the rest black ; eyes prominent, 

 their inner border distinctly sinuate, their upper edge bordered 

 by a deep groove, which is prolonged obliquely downwards and

 Thorax twice as broad as long ; sides obtusely angled behind the 

 middle, thence obliquely converging to the apex ; anterior angles 

 tuberculate, hinder armed with an obtuse tooth ; above trans- 

 versely convex, anterior margin bordered within by a deep trans- 

 verse groove ; surface subremotely impressed with large deep 

 punctures. Scutellum trigonate, its apex rounded. Elytra broader
