the much shorter basal joint of its hind tarsi. I am doubtful of 

 the sex of the example before me (it is difficult to determine the 

 sex of a Chalcopterus unless both sexes can be examined), but it 

 is probably a female. In my tabulation of Chalcopterus (P.L.S., 

 N.S.W., 1893) this species may be placed beside cupreus, Fab. 

 (p. 60) though its prothorax is not quite "fully" twice as wide 

 as long (but it is notably wider than in brevipes), from which it 

 may be thus distinguished : — 



J. Prothorax twice (or all but twice) as wide as long.

E. persimilis, sp. no v. Mas. Picea, elytris ruf escentibus ; minus

Closely allied to E. Meyricki, Blackb., with similar elytra! 

 pattern (about six narrow vittse of whitish pubescence on each 

 elytron) and the same number (nine) of antennal rami ; differing 

 from it in the ramus of the third joint being fully three-fourths 

 of the length of the longest ramus (in Meyricki it is scarcely 

 more than half) and scarcely more distant from the second ramus 

 than the second ramus is from the third. It is moreover a more 

 robust insect, less narrowed behind, with the prothorax less 

 elongate and having posterior angles less strongly directed hind- 

 ward. The other previously described species having nine 

 antennal rami are pruinosa, Gerst., and perthensis, Blackb., 

 neither of which has elytra marked with longitudinal pubescent 

 vittse ; moreover pruinosa has the first antennal ramus even 

 shorter than that of Meyricki, a much more elongate prothorax,
