198 Phytophaga Malay ana. 



obliquely deflexed in front; surface finely but distinctly punc- 

 tured. Scutellum slightly broader at the base than long, its apex 

 ol)soletely angled. Elytra oblong, convex, impressed below the 

 basilar space ; strioD impressed on the anterior disk with round 

 shallow punctures, on the hinder disk they are indistinct, and 

 before reaching the apex of the elytron entirely obsolete ; the 

 ninth to the twelfth stria; are ill defined and entirely obsolete below 

 the middle of the disk ; interspaces plane. 



Smaller and narrower than the preceding insect, and the elytra 

 are differently punctured. 



51. Rhyparlda tiimifrons, n. sp. 



Oblonga, convexa, picea, nitida ; vertice tumido, convexo ; tho- 

 race subcrebre punctato, obsolete strigoso-reticulato ; elytris 

 thorace vix latioribus, infra basin non excavatis ; striis in- 

 tegris, ante medium leviter sulcatis, sat foriiter punctatis, 

 punctis pone medium minus fortiter impressis ; interspatiis 

 antice leviter convexiusculis, postice planis; femoribus subtus 

 dente brevi armatis. 



Long. 2 lin. 



Hab. Borneo. 



Vertex swollen, convex ; whole surface of head granulosa, 

 covered with shallow oblong punctures, middle of front just 

 above the eyes impressed with a shallow longitudinal fovea; 

 epistome on the same plane and forming a single piece with the 

 front, the apical sutures being entirely wanting ; its anterior border 

 moderately concave-emarginate, angles of the notch not produced ; 

 jaws black. Thorax twice as broad as long, sides rounded and 

 converging from base to apex, anterior angles obsolete, hinder 

 angles tuberculate ; surface covered with coarse punctures, inter- 

 spaces indistinctly reticulate-strigose. Scutellum scarcely longer 

 than broad, its apex distinctly angular. Elytra scarcely broader 

 than the thorax, not excavated below the basilar space ; strife 

 strongly punctured, slightly sulcate on the anterior disk, the in- 

 terspaces obsoletely convex ; behind the middle the punctures are 

 finer, and the interspaces plane. 



The swollen head, and obliquely deflexed sides of the thorax 

 m front, will serve to separate this species from its allies ; viz., 

 those in which the thorax is broad and has its anterior angles 

 obsolete.
