 being abbreviated in front and bebind, and a line dorsallj' of tbis vitta ; ou elytra a 

 broad semicircular band common to both elytra, widest at sutnre, sbonlder-angle, a 

 snbcironlar, sntural patch jnst bebind middle, divided at the sntnre, inclnding 

 anteriorly a vinaceous bnff dot on each elytram, an evenly curved band from side to 

 side, crossing suture 3 mm. before apex, being convex behind; on underside, a lateral 

 vitta on prothorax, a large lateral patch on metasternum, and a series of lateral 

 patches on abdomen. A large lateral patch from middle of prosternnm to apical 

 edge of metasternum, and another, sublateral, bordered with brown, on third and

 A frontal vitta at eye, a lateral vitta on prothorax beneath, a large lateral patch 

 extending from angle of coxal cavity of prosternum to end of metasternum, including 

 a large, olive, irregular patch on metasternum, a lateral spot on first abdominal 

 segment, a smaller one on second, a sharply defined sublateral patch on third and 

 fourth segments, chalky white ; middle of sterna cinnamon : middle of first and 

 second abdominal segments and a band along ajjical edge of fifth grey. Frons 

 cinnamon, excej)ting a triangular vinaceous mesial .'ipace which extends over 

 occiput ; a narrow mesial vitta and oblique broad lateral one ou occiput cinnamon, 

 bordered with black. These lateral black border-lines continued over the pronotum, 

 meeting before the base of tho latter; two black lateral lines above the white vitta, 

 curved like this. Elytra : a semicircular baud of two black lines from side to side, 

 crossing suture behind scutellum, narrowest at lateral margin where the lines are 

 confluent ; a subcircnlar, somewhat transverse cinnamon area, the centre of which 

 lies behind middle of :^ntnre, encircled by a black line ; within this area another 

 black I'ing, somewhat longitudinal ; this second line bordered with vinaceous grey 

 in front, while the first line is bordered with grey laterally and, slightly, behind ; 

 a continuous cinnamon and black transverse band before apex, concave anteriorly, 

 reacliing from side to side ; slniulder black beueatli ; the vinaceous buff apical and 

 posliinnieral areas shaded with grey. Antenna Iirown, scape and second segment
