28 Mr. J. S. Baly on new Species of Phytophagous Beetles. 



Oblong, convex^ shining testaceous ; elytra bright metallic 

 green, punctate-striate, the punctures less regularly placed on 

 the striae on the outer disk than in the foregoing species; face 

 somewhat broader, slightly swollen, irregularly punctured; epi- 

 stome separated from the face by a nearly semicircular groove, 

 the middle of which is slightly produced upwards and angular. 



Gonioctena ruhripennis. 



G. oblonga, convexa, nigra, nitida ; elytris punctato-striatis, sordide 



rufo-fulvis ; antennis basi fulvis. 

 Long. 2^-3 lin. 



Hab. Japan. 



Oblong, convex, shining black ; elytra obscure rufo-fulvous. 

 Thorax at the base more than twice as broad as long; sides 

 narrowly margined, rotundate-angustate, all the angles acute ; 

 above convex, sparingly covered with fine punctures on the disk; 

 sides coarsely and more closely punctured, their outer edge, just 

 within the lateral border, slightly thickened. Scutellum semi- 

 ovate. Elytra scarcely broader than the base of the thorax; 

 sides subparallel ; apex regularly rounded ; above convex, trans- 

 versely depressed on the disk below the humeral callus; each 

 elytron impressed with eleven regular rows of distinct punctures, 

 the first abbreviated, interspace between the tenth and eleventh 

 rows slightly thickened, the others flat, subremotely covered with 

 fine but distinct punctures; under surface of body coarsely 

 punctured. 



Gonioctena nigro-plagata. 



G. oblonga, convexa, fulva, nitida ; elytris pimctato-striatis ; scutello 

 elytrorumque puncto apicali plagisque octo, 4 vix infra basin, 4 

 pone medium, transversim positis, nigris. 



Var. A. elytrorum maculis inter se confluentibus, facie inferiore 

 piceo tincta. 



Long. 3-3^ lin. 



Hab. Japan. 



Oblong, convex. Thorax more than twice as broad as long, 

 sides rotundate-angustate, very narrowly margined, posterior 

 angles acute, the anterior subacute ; above convex ; sides coarsely 

 punctured, a narrow space just within the outer border thickened, 

 impuuctate ; disk remotely punctured ; medial line near the base 

 impressed with a short longitudinal groove. Elytra similar in 

 form and sculpture to the preceding species, the punctures being, 

 however, rather coarser and somewhat less regularly placed on 

 the striae ; each elytron marked with a small spot at the sutural 

 angle and four large patches on the disk, shining black ; these 

 latter, which vary in shape, are placed in two transverse rows,
