20 Mr. J. S. Baly on new Species of Phijtophagous Beetles. 



gibbous behind the middle, thence obliquely deflexed to their 

 apex. 



Genus Chrysomela, Linn. 



Chrysomela eximia. 



C. elongata, convexa, nitida, cseruleo-senea, abdominis segmentorum 

 marginibus pedibusque lsete seneis, supra viridi-senea ; antennis 

 extrorsum, plaga frontali, thoracis basi utrinque ampliata vittaque 

 centrali, scutello elytrorumque sutura vittaque disco'idali lsete 

 purpureas ; thorace irregulariter punctato, lateribus incrassatis, 

 intra marginem longitudinaliter excavatis, profunde varioloso- 

 punctatis ; elytris sat fortiter subcrebre punctatis, punctis in striis 

 confusis dispositis, interspatiis aciculatis, irregulariter elevatis, ad 

 apicem subverrucosis. 



Var. A. supra cupro-eenea, signaturis viridi-seneis. 



Long. 5-6 lin. 



Hab. Mantchuria ; collected by Mr. Bowring. 



Elongate, convex, nitidous; body beneath metallic blue, with 

 a greenish tinge ; apical border of the abdominal segments, to- 

 gether with the legs, brassy ; body above brassy-green. Head 

 nearly perpendicular ; face broad, distinctly punctured ; epistome 

 slightly depressed, separated from the face by an angular groove, 

 from the apex of which an ill-defined longitudinal grooved line 

 extends upwards on the face ; the surface of the latter on either 

 side this groove is irregularly excavated; vertex with a large 

 purple patch ; antennae scarcely half the length of the body, 

 their outer half purple, and covered with a short adpressed fus- 

 cous pubescence. Thorax twice as broad as long ; sides mode- 

 rately ampliate-rotundate, nearly straight and obsoletely sinuate 

 at their base ; apical margin broadly excavated ; upper surface 

 moderately convex, irregularly punctured; sides thickened, lon- 

 gitudinally excavated within, surface of excavated portion covered 

 with large irregularly confluent variolose punctures ; a longitu- 

 dinal vitta down the middle of the disk, and a broad basal fascia, 

 dilated at either end, but abbreviated just before reaching the 

 lateral border, bright purple. Scutellum semiovate, obtuse, 

 bright purple, its surface covered with irregular depressions. 

 Elytra narrowly oblong, slightly broader than the thorax, nearly 

 five times its length ; sides subparallel ; apex rounded ; surface 

 somewhat closely covered with coarse, irregular, deeply impressed 

 punctures, arranged for the most part in irregular longitudinal 

 strife ; general surface of the elytra irregularly thickened, acicu- 

 late, subverrucose towards the apex ; a sutural line and a broad 

 vitta on the disk, abbreviated at the base, bright purple. 



This splendid species is very closely allied to our Ch. fulgida, 

 Stephens ; it is, however, nearly twice the size, and proportionately
