Hab. Tasmania—Hobart. 
I refer with some doubt a very variable Chalcopterus 
obtained in plenty in Tasmania by Mr. Walker to this 
species, the type of which was from Melbourne. The 
Rev. T. Blackburn in his recent papers on the genus 
Chalcopterus does not mention any species specially as 
from ‘l'asmania. 
Chalcopterus semiticus. 
Amarygmus semiticus, Pasc., Ann. and Mag. Nat. Hist. 
(4), ii., p. 349 (1869). 
Hab. N. Australia—Cape Bougainville. 
One specimen of this species has been sent by Mr. 
Walker to the British Museum. It agrees well with the 
type from Port Denison. C. semiticus is apparently 
unknown to Mr. Blackburn (cf. Proc. Linn. Soc. N.S.W. 
(2), viii., p. 69).
