204 Phytophaga Malay ana. 



slightly rounded to the apex ; upper surface transversely convex, 

 sides obliquely deflexed in front, closely covered with irregular 

 longitudinal raised strigae, which anastomose freely with one 

 another, each interstice occupied by a single row of distinct 

 somewhat deeply impressed punctures. Scutellum oblong, its 

 apex obtuse. The elytra appear to vary considerably in colour ; 

 usually on the basilar space is an ill-defined fulvous patch ; in 

 other specimens the whole surface is fulvous, with the suture and 

 some small patches on the disk piceous ; striae entire, sulcate, 

 interspaces convex. 



60. Rhyparida Amboinensis, n. sp. 



Oblonga, convexa, obscure picea, nitida ; antennis fulvis ; tho- 

 race elytris fere aequilato, fere impunctato ; elytris parallelis, 

 infra basin non excavatis ; striis integris, sat fortiter punctatis, 

 punctis pone medium minus fortiter impressis ; interspatiis 

 planis ; femoribus muticis. 



Long. Ij lin. 



Hab. Amboina. 



Head granulose, nearly impunctate ; frontal groove obsolete ; 

 epistome forming a single piece with the front, its surface concave, 

 deeply punctured, anterior margin deeply rotundate-emarginate, 

 angles of the emargination produced, subacute ; labrum and an- 

 tennae fulvous ; jaws black. Thorax nearly twice as broad as 

 long ; sides nearly straight and parallel behind the middle, ob- 

 liquely rounded and converging from the middle to the apex, all 

 the angles armed with a small tooth ; transversely convex above, 

 sides obliquely deflexed in front; surface shining, very sparingly 

 and very remotely punctured. Elytra oblong-ovate, slightly 

 excavated below the basilar space and within the humeral 

 callus; striae strongly punctured, entire, the punctures rather 

 less strongly impressed behind the middle. 



The form of the epistome will separate this species from its 

 allies. 



61. Rhyparida nucea, n. sp. 



Elongata, picea, subnitida ; thorace subcylindrico, fortiter punc- 

 tato ; elytris opacis, thorace multo latioribus, oblongis, infra 

 basin excavatis ; striis sulcatis, fortiter punctatis, pone apicem
