 There can be little doubt about the above synonomy. 

 I have, unfortunately, not seen specimens from Adelaide, so 

 cannot check 0. darwinii and fcrtumni of Westwood.* A 

 good photographic illustration of 0. doddi, Wand., does 

 not differ in any respect from numerous Tasmanian ex- 



*Since the above was written, T have received for identification 

 from the Director of the South Australian Museum, ten specimens 

 of Cijriidx, comprising the following species: — 

 Pterodontia, sp. 2 specimens. Flinders Range. 

 Oncodes hasilis. Walk., 5 males, 1 female, Adelaide. 

 ,, ,, 1 female, Mullewa, W.A. 



,, ,, 1 female, Lawson, N.S.W. 



The Adelaide O. hasilis conforms with specimens from Cradle Mt., 

 Tasmania, in every respect in the male. The female is too inferior m 

 condition for comparative examination. Both sexes, however, are large. 

 The West Australian specimen is ijormal. but the abdomen shows 

 slisht discoloration towards that of pygmxus, as described by White. 

 The addition of Western Australia to the distribution of this species 

 seems to suggest that the insect will be found to occur throughout 

 -Australia.
