NEW PHYTOPHAGOUS COLEOPTERA 201 



body , fulvous , the outer joints rather short. Thorax much nar- 

 rowed in front, the sides rounded, surface finely and rather 

 closely punctured. Elytra with about ten regular and deeply 

 impressed striae which are scarcely visibly punctured, the in- 

 terstices being convex near the sides; from the humeral callus 

 which is distinctly raised and elongate, a short oblique costa 

 runs to the lateral margin towards its middle interrupting the 

 striae at the same place. Femora unarmed. 



Buitenzorg (Lansberge) ; Java , Tcibodas (0. Beccari). 



From R. pmguis and R. ovalis, the only species with which 

 the present one can be confounded, the latter is distinguished 

 by the costa at the shoulder and the unarmed femora. 



18. IFtlxyparida laevifrons, n. sp. 



Fulvous. Head impunctate. Thorax extremely closely and fi- 

 nely punctured. Elytra deeply depressed below the base, strongly 

 punctate below the latter, impunctate near the apex. 



Length 2-2 7, lines. 



Head with a deeply impressed longitudinal groove, impunc- 

 tate, opaque; episteme scarcely broader than long, separated 

 from the face, its surface entirely impunctate; eyes nearly en- 

 tire. Antennae two thirds the length of the body, entirely light 

 fulvous. Thorax broadly transverse , its sides much rounded , the 

 anterior angles obtuse, posterior ones with a short tooth, sur- 

 face very minutely and closely punctured, with an obsolete 

 transverse depression in front of the anterior margin. Elytra as 

 broad as the thorax not much more than twice its length, the 

 base distinctly elevated and transversely depressed, strongly 

 punctured within this depression only , the base itself nearly 

 impunctate , and the striae becoming very fine below the middle, 

 but the fifth stria extending upwards to the base, the inter- 

 stices plane and impunctate ; posterior femora with a very mi- 

 nute tooth.
