222 Phytophaga Malayana. 



sliglitly angulate-cmarginate ; jaws piceous ; eyes prominent, 

 ovate, their inner border slightly sinuate. Thorax twice as broad 

 as long ; sides obsoletely angular behind the middle, obliquely 

 diverging at the base, thence obliquely converging and slightly 

 rounded to the apex, apical angles armed with a subacute tooth ; 

 upper surface finely and distantly punctured, lateral border slightly 

 dilated ; the anterior border bounded within by a transverse 

 groove which extends entirely across the thorax ; anterior border 

 piceous. Scutellum trigonate, its apex obtuse. Elytra scarcely 

 broader than the thorax, parallel,' excavated below the basilar 

 space and within the humeral callus, the latter prominent; striae 

 somewhat strongly punctured, slightly sulcate, the interspaces 

 convex ; on the hinder third of the surface the striae are nearly 

 obsolete, and the interspaces plane ; on the subbasilar excavation 

 is a small pale piceous patch.

Head smooth, nearly impunctale ; epistome wedge-shaped, its 

 apex not separated from the front, anterior border subangulate- 

 emarginate ; encarpae separated from the front by a shallow 

 groove; jaws nigro-piceous; eyes black, their inner edge sinuate; 

 outer half of antennae stained with piceous. Thorax more than 

 twice as broad as long ; sides rounded, obtusely angled behind 

 the middle, thence obliquely converging and slightly rounded to 

 the apex ; anterior and posterior angles each armed with an ob- 

 tuse tooth ; above transversely convex, remotely impressed with 

 deep punctures ; the anterior border bounded within by a deep 

 transverse groove which extends entirely across the thorax, its 

 surface impressed with a row of indistinct punctures ; two small 

 spots on either side of the disk, together with the anterior margin,
