 Long. 4 lin. 



C. elongate, scarcely broader behind ; posterior angles of elytra 

 produced into a large, flattened, acnte spine ; pale fiilvons ; eyes 

 and antenna; black, five terminal joints of the latter rufo-fuscous ; 

 elytra pale lTlfo-^'iolaceons -with a faint metallic reflexion, the 

 posterior spine and a short vitta on the shoulders black ; each 

 elytron >\ith foiu- large ill-defined pale fulvous patches covering 

 nearly the whole of the surface. Head smooth and shining, obso-

 half the body, joints cylindi'ical, second twice as long as the fii-st, 

 foul- terminal joints short, covered with short adpressed fulvous 

 hairs. Thorax broader at the base than long ; sides indistinctly

 bidentate at the extreme base, anterior angles shghtly produced 

 riito an obtuse tooth ; anterior margin shghtly produced in the 

 middle, sinuate on either side ; above cylindiical on the sides, 

 flattened on the disc, transversely excavated at the base ; coarsely 

 punctured, anterior margin smooth, impunctate, middle of the 

 disc -^vith a narrow, slightly raised longitudinal line ; basal lobe 

 grooved, deflexed. Scutellum indistinctly margined on the sides, 

 transversely grooved. Elytra broader than the thorax, shghtly

 base for two-tliit'ds the length of the elytron ; the tliird towards 

 the apex, confluent Avith the second, common, and forming with 

 the one on the opposite elytron a broad transverse patch ; the
