 Wilcannia. 



C. IMPERIALIS, sp.nov, 



G. colosso affinis ; differt capite inter oculos paullo minus 



crebre punctulato et (exempli typici) inter oculos utrinque 



longitudinaliter carinato, antennis apicem versus magis 



incrassatis (articulis 8-10 quam prsecedentes haud multo 



brevioribus), elytrorum puncturis seriatis multo majoribus et 



interstitiis nullo modo convexis fortiter punctulatis, meta- 



sterno minus fortiter magis sparsim sculpturato, et (ab 



exemplis visis) coloribus multo magis splendidis, — sc. viridi 



aureo purpureo cyaneoque-longitudinaliter vittatim positis 



(fere ut G. superhi, Blackb.). [Long. 10, lat. 5i lines. 



This species is near G. colossus, Blackb. The style of colouring 



is so entirely different that it may probably be relied on as a 



character. The difference in the antennae may be unreliable, as 



T am not sure of the sex of either species. The carina on either 



side of the interval between the eyes is probably constant. The 



autero-internal corner of the eyes is much rounded off, so that the 



interval between the eyes looks much less parallel than in 



C. colossus (the head is almost exactly like that of C. carinaiiceps 



except in not having distinct ocular sulci). The punctures in the 



elytral series are considerably stronger than in G. variabilis, 



Blessig (they are scarcely less strong than in C. 2}unctij)ennis, 



Macl.), whereas in G. colossus the corresponding punctures are 



very little less fine and close than in cuprijoennis, Hope. The 



interstices on the elytra are more strongly punctured than in 



almost any other Ghalcoptenhs, very little less so than in 



G. rugosijyennis, Macl., while in G. colossus the punctures of the 



interstices are exceptionally fine.
