Head densely and shallowly punctate ; face feebly concave. 

 Scape more than twice the length of funicle, and about one-fourth 

 shorter than club, the latter large and briefly oval. Prothorax 

 distinctly longer than wide, sides incurved to middle, with small 

 sparse punctures becoming denser and larger at base and apex. 

 Elytra almost twice the length of prothorax, sides feebly inflated 

 about middle, and suddenly diminishing near apex, each at apex 

 with two conical projections, of which the largest is at apex 

 itself and almost perpendicular, the other is just above it and 

 projects slightly outwards; there is also a minute inner projection; 

 feebly seriate-punctate, the interstices very feebly punctate, the 

 series of punctures in scarcely defined strise on basal half, but 

 beyond the middle the striae become deep and very distinct, with 

 the interstices blackish and opaque. Under surface sparsely 

 punctate, the apical segment, however, densely punctate. Legs 

 stout; tibiae obliquely ridged; tarsi long and thin. Length 4J mm. 



9. Differs in having the head more distinctly punctate, the 

 vertex with a narrow shining carina (scarcely traceable in the 

 male), the elytra rounded posteriorly and without conical pro- 

 jections, the summit of the posterior declivity densely granulate, 

 and the sides (except at apex) perfectly parallel. 



Hah. — Tasmania, widely distributed. 



This species attacks practically all the native trees and many 

 cultivated ones, including the apple, plum and apricot. Trees of 

 Acacia decurrens and A. dealhata that have been stripped of 

 bark, and Eucalypts that have been ring-barked, are soon riddled 

 by it; even long dead wood is sometimes attacked. Perfectly 

 healthy fruit trees are sometimes attacked and rather seriously 

 injured by them, especially when in the vicinit}^ of new clearings. 



Although so common in Tasmania, I have seen it from nowhere 

 else. From the previously described species the apical third of 

 the elytra renders it abundantly distinct. 



Platypus australis, Chp. 

 The female of this species, as such, was unknown to Chapuis. 

 I have taken numerous specimens of both sexes (some in copula) on 

 the Tweed and Richmond Rivers, and it appears to me that the
