antennis violaceis ; thorace bronzeo fere bilobato, postice con- 

 stricto, elytris nigricantibus, lateribus externe trilunatis, maculis 

 albidis notatis, septem punctis viridibus in singulo elytrorum fere 

 ad suturam positis ; corpore infrci violaceo, femoribus, tibiis tar- 

 sisque concoloribus, tibiis autem ad basin flavo-maculatis. Long, 

 lin. 3, lat. lin. 1;^. 

 The above elegant insect appears to be a form differing from any 

 yet received from New Holland. 



Carenum Smaragdulum, Hope. Viride, capita nigro, foveisque 

 binis impresso, thorace virescenti semicirculari, margine omni ele- 

 vatd ; elytris late viridibus glabris nitidis, marginibus externis 

 elevatis et auratis ; corpore infrd, piceo lateribus aneo-tinctis, 

 pedibus concoloribus. Long. lin. 9, lat. lin. 2^. 

 This beautiful species I received lately from Western Australia, 

 and now describe it, as it is apparently quite unknown. It is pro- 

 bable that Carenum will be found to be peculiar to New Holland. No 

 true Scarites of my acquaintance is of any colour but black or 

 brown. 



Eutomus megacephalus, Hope. Cylindricus, niger, nitidus, capite 

 maximo pronoto viridi, elytris leevibus cupreo -viridibus, tibiis an- 

 ticis dente unico apicali externo. Long. lin. 8. 

 ^Enigma (Newm.) cyanipenne, Hope. Atro-piceum, capite nigro 

 punctulato, antennis tomentosis, quatuor primis articulis atris, re- 

 liquis fuscis ; thorace cordato, antic^ posticeque truncato, disco 

 punctulato ; elytris cyaneis, striato-punctatis, spatiis, inter strias 

 punctulatis ; corpore infrd, piceo, pedibus concoloribus. Long, 

 lin. 7, lat. lin. 1^. 

 This species is the second that has hitherto been described. I 

 (Consider it as a true Helluo. 



Enigma unicolor, Hope. Fusco-piceum, antennis tomentosis, tho- 

 race cordato punctulato, elytrisque subcostatis et striato-punctatis, 

 corporeque infrh concolori. Long. lin. 7, lat. lin. 1^. 

 As this species is also a native of New Holland, and is unknown 

 to entomologists, it is here described, although it was not received 

 from Port Essington,

 Antenna ll-articulata, articulo \*"^ crasso, reliquis aqualibus. Cly-
