Phytophaga Malayana. 211 



the same plane and forming a single piece with the front, apical 

 sutures entirely obsolete, the lateral very indistinct ; middle por- 

 tion of anterior margin concave-emarginate, angles of the notch 

 slightly produced, obtuse ; jaws nigro-piceous ; basal joints of 

 antennae fulvous. Thorax half as broad again as long ; sides 

 rounded, slightly converging in front, all the angles tuberculate ; 

 above very convex, sides deflexed in front ; surface strongly but 

 not closely punctured, the puncturing finer near the middle of the 

 anterior border. Scutellum longer than broad, semiovate. Elytra 

 much broader than the thorax, parallel, broadly excavated below 

 the basilar space, longitudinally sulcate within the humeral 

 callus, the latter thickened, prominent ; basilar space slightly 

 thickened ; striae strongly punctured on the anterior disk, finely 

 punctured on the basilar space and on the hinder disk, nearly 

 obsolete towards the apex ; on the anterior outer disk is a strongly- 

 raised tuberculate and more or less interrupted ridge, extending 

 from the humeral callus to the middle of the elytron, its hinder 

 portion being slightly flexuous, and becoming gradually lost in 

 the general surface of the disk.

Anguste oblonga, parallela, convexa, pallide fulva, nitida ; tho- 

 race elytris fere aequilato, lateribus angulatis, dorso rude sub- 

 remote punctato ; elytris oblongis, infra basin obsolete ex- 

 cavatis ; striis integris, sulcatis ; interspatiis convexiusculis, 

 iis prope marginem lateralem subcostatis ; femoribus muticis.

Hab. Eastern portion of Ceram. 



Head moderately prominent, coarsely punctured ; epistome form- 

 ing a single piece with the front, its anterior border subangulate- 

 emarginate ; jaws piceous ; eyes prominent, entire; antennae two- 

 thirds the length of the body. Thorax twice as broad as long ; 

 sides angled just behind the middle, narrowly edged with piceous; 

 upper surface coarsely punctured. Elytra scarcely broader than 

 the thorax, parallel, very faintly impressed below the basilar 

 space; striae sulcate, strongly punctured; interspaces slightly 

 convex, those near the lateral border thickened. 



The species before us is the only instance known to me of a 

 distinctly angular thorax in the genus Rhyparida.
