XANTHOPHCEA. 



X. concinna, sp. nov. Elongata ; sat nitida ; rufo-testacea, 

 elytris pallidioribus singulis vittis binis nigris (altera sutu- 

 rflli, altera submarginali) integris ornatis ; oculis raodicis, 

 crebre minus leviter granulatis ; prothorace quam longiori 

 ut 2J ad 2 latiori, supra transversim subfortiter strigato et 

 leviter punctulato, parte marginal! late deplanata et leviter 

 recur va, lateribus leviter arcuatis postice modice sinuatis, 

 angulis posticis acutis sat fortiter extrorsum directis ; 

 elytris striatis, interstitiis sat planis minus crebre punctulatis 

 (3" postice punctura setigera unica impresso). Long., 4 1.; 

 lat., If 1. 

 The sutural vitta of the elytra covers the sutural and second 



interstices ; the lateral vitta covers the sixth, seventh, and 



eighth interstices on each elytron aP the vittse are entire and 



very sharply defined.
