Tachys ectromioides Sloane 
Sloane 1896, 356, 359; 1898, 477; 1921, 195 (prothorax), 198, 204. 
Sloane described this species as with “. . . elytra testaceous, a very 
wide dark piceous fascia across disc considerably behind base, apex 
widely piceous . . .” and “. . . third elytral interval with two small 
setigerous punctures — the anterior just before, the posterior just 
behind discoidal piceous fascia . . .” The type of the species (now in 
the Macleay Museum at Sydney) was said to be from Donnybrook, 
Western Australia, but Sloane later (1898) suggested that this was 
probably an error. The species has been found at the Richmond River, 
northern New South Wales (Sloane 1898) ; on the Blue Mts., New 
South Wales; and near Melbourne, Victoria (Sloane 1921, 204). I 
have not collected it but have briefly examined a specimen at the 
British Museum, unfortunately without looking for the dorsal elytral 
punctures. The possible habitat of the species is suggested in discussion 
of the group.

as very fine transverse lines on elytra, which are vaguely iridescent.
