MR. J. S. BALY ON" SOME GENEEA 



2. Charidea Fortunei. Elongata, picea, nitida, antennis nigris, 

 supra subnitida, pube suberecta grisea sparse vestita ; thorace elytris- 

 que sanguineis; thorace quam longo paullo latiore, fortiter punctato, 

 disci medio bicalloso, callis Isevibus ; elytris parallelis, transversim 

 convexis, fortiter punctato-striatis, utrisque bicostatis. Long. 

 2f lin. 



Hah. Korthern China ; collected by the late Mr. Fortune. 



Head clothed with griseous hairs ; vertex convex, separated 

 from tlie front by a deep transverse groove ; encarpae contiguous, 

 pyriform, longer tiian broad, extending downwards as far as the 

 insertion of the antennae, iuteranteimal space excavated; lower 

 portion of clypeus transversely excavated ; antennae nearly as 

 long as the body, moderately robust, filiform, the second joint 

 short, the third nearly twice its length, the fourth and succeeding 

 ones each equal in length to the third. Thorax broader than 

 long ; sides straight and nearly parallel from the base to beyond 

 the middle, thence slightly rounded and obliquely converging 

 towards the apex, the anterior angle obtuse, the hinder one acute ; 

 upper surface moderately convex, coarsely and strongly punc- 

 tured ; on the disk are two large, slightly raised smooth callo- 

 sities, separated from each other by a narrow groove, but bounded 

 at the base, apex, and the outer margin by a deep irregular sulca- 

 tion ; surface of disk more or less stained with piceous. Elytra 

 rather broader than the thorax, parallel on the sides, transversely 

 convex, not excavated below the basilar space ; each elytron with 

 twelve rows of large, deeply impressed punctures ; the fourth 

 interspace at its base, the fifth and ninth for nearly their whole 

 length, confluent at their apices, strongly costate ; upper portions 

 of the tenth and eleventh interspaces subcostate. 



This species may be known from C. punctato-striata by the 

 pubescence on the upper surface of the body, by the strongly 

 raised costae on the elytra, and by the piceous colour of the 

 head, under surface, and legs. The anterior acetabula in this 

 insect are entirely closed. 



Genus Plattxantha, Baly. 



1. Platyxantha clypeata. Elongata, paraliela, dorso deplanata, 

 flava, nitida, thorace, inandibulis apice oculisque nigris ; thorace 

 transverso, lateribus e basi ad ultra medium rectis, paullo divergenti- 

 bus, hinc apicem versus convergentibus ; disco modice convexo, laevi, 

 utrinque fovea parva, plus minusve distincta, impresso ; elytris paral- 

 lelis, ad latera convexis, dorso deplanatis, tenuiter confuse punctatis ;
