480 AUSTRALIAN COLEOPTERA, WITH DESCRIPTIONS OF NEW SPECIES^ 



little less than half again as wide as the front which is gently 

 concave, with obtuse angles ; the sides are nearly straight from 

 the base to beyond the middle, and then arcuately convergent ; 

 the base is gently bisinuate, widely roundly and rather strongly 

 lobed in the middle, and very exactly applied to the elytra ; the 

 hind angles are well-defined ; the coarser puncturation is in the 

 middle sparing, and not much coar&er than that of the general 

 surface, but is larger and closer towards the margins. The elytra 

 are very distinctly punctulate-striate quite to the apex, the inter- 

 stices being almost perfectly flat. The claws are not far from 

 being simple, the basal tooth being ill-defined, feeble, wide and 

 very obtuse. The 3rd joint of the antennae is considerably longer 

 than the 4th. 



This insect must be near the Tasmanian C. pacifica, Er., and 

 luteicornis, Er., from both of which (apart from colour differences) 

 it differs in having the sculpture of the elytra not obsolete near 

 the apex ; from C. acervata, Germ., it differs in colour, shape and 

 sculpture as well as size. 



Not rare near Adelaide ; generally found (like most of its con- 

 geners) under bark. 



Chalcolampra hursti, sp.nov. 



Robusta ; nigro-senea ; sat nitida ; capite (nonnullis exemplis), 

 ore, palpis, antennis, pedibusque piceo-rufis (his, plurimis exemplis, 

 obscurioribus) ; prothorace duplo-punctulato ; elytris sat fortiter 

 punctulato-striatis ; interstitiis late leviter insequaliter convexis, 

 laevigatis. [Long. 3-3i, lat. If lines. 



The antennse are decidedly less than half as long as the whole 

 insect, and slender, their 3rd joint much longer than the 4th which 

 is equal to the 5th. The prothorax is considerably more than half 

 again as wide as long, its base about half again as wide as its 

 front which is rather strongly concave ; the sides are contracted 

 in a gentle curve from base to apex ; the surface is covered with 

 very fine lightly impressed and by no means close puncturation,
