foveate unless at intersection of middle line. Elytra 1/3 or more wider 
than prothorax (E/P 1.34 & 1.44) ; margins behind humeri faintly 
subserrate and setulose ; sutural striae entire, stria 5 well impressed in 
about basal half and reaching humerus, stria 2 less impressed, and 
striae 3 and 4 irregularly and usually rather faintly indicated; apical 
striole reduced to a conspicuous elongate puncture. Length c. 1.8; 
width c. 0.7 mm. 
Holotype cf (M. C. Z. Type No. 30328) and 10 paratypes all 
from the King River just below the crossing of the road from Lake 
St. Clair to Queenstown. The specimens were taken with hobarti, 
under stones, on stone-and-gravel bars. 
This species is about the size of typical T. murrumbidgensis. I do 
not have specimens of the latter, but kingi evidently differs in having 
elytral striae 2-4 less distinct, clypeus not impressed, and upper surface 
more shining.

A rather elongate, black or blackish species, with characters of 
hobarti group. Head .87 & .88 width prothorax; clypeus not or not 
distinctly impressed anteriority (checked in all specimens). Prothorax 
subcordate; width/length 1.3 1 & 1.34, base/apex .93 & .91 ; base/head 
.82 & .81; posterior angles right-acute, nearer base than in preceding 
species but separated from basal lobe by brief, strong sinuations. 
Elytra much wider than prothorax (E/P 1.47 & 1.46) ; each with 5 
or 6 discal striae (stria 6 variable). Length 2. 3-2. 7; width 0.8-1.0 
mm. 
This species was described from near Hobart, Tasmania. I redis- 
covered it at the King River and later found a specimen by the Mersey 
River, Tasmania, as noted in the preceding general discussion of 
Tachys. If the synonymy suggested above is correct, this species has 
been found on the mainland of Australia on the bank of the Watts 
River, a tributary of the Yarra, east of Melbourne, Victoria (watt- 
sense) , and at Tamworth, New South Wales (leai ) .
