oblique and strongly converging posteriorly, strongly but briefly 
sinuate before posterior angles; latter forming small, sub-basal, rec- 
tangular projections; apex truncate; base subtruncate; disc with 
anterior transverse impression and middle line almost obsolete but 
latter coarse basally; sulcus coarsely foveate. Elytra more than 
wider than prothorax (E/P 1.57), probably widest about middle 
(slightly spread), not margined basally (margin ending a little inside 
humeri) ; margins not visibly serrate or setulose (at 54X ) ; sutural 
stria entire, punctate anteriorly, groove-like posteriorly ; other dorsal 
striae obliterated, including 5th> which is at most faintly indicated 
toward base ; apical stride reduced to a coarse slightly elongate punc- 
ture on declivity, nearer margin than suture; 3 dorsal punctures on 
each elytron before anterior * 4 , near middle, and behind Y\.. Length 
c. 2.5 ; width c. .95 mm. 
Holotype (M. C. Z. Type No. 30327) $ from Termed (north of 
Bateman’s Bay and east of the upper Clyde River), southern New 
South Wales, October 1957, taken by myself. It was actually found 
northwest of Termeil, well up in the hills, where I followed a system 
of wood roads nearly to (south of) a conspicuous summit called the 
Pigeon House. Here, in a small valley of eucalyptus woods, was a 
small brook, nearly dry but with water still in the pools, which were 
margined by sand bars. The single specimen of the present species was 
taken by washing sand at the water’s edge. 
The obliteration of the elytral striae (except the sutural) makes 
this a distinct and easily recognizable species. 
Tachys kingi n. sp. 
With characters of hobarti group as described above. Small, moder- 
ately elongate, moderately convex; dark rufous, head slightly darker, 
appendages not much paler; shining, reticulate microsculpture faint 
above but head and pronotum distinctly, sparsely punctulate. Head 
.86 & .87 width prothorax (in <$ $ measured) ; antennae with middle 
segments not quite 2X long as wide; clypeus truncate, not impressed 
anteriorly (checked in all specimens) ; frontal sulci irregularly sub- 
parallel, reaching and diverging on clypeus. Prothorax subcordate, 
width/length 1.30 & 1.28; base/apex .89 & .93; base/head .81 & .79; 
sides rounded anteriorly, oblique and strongly converging posteriorly, 
rather strongly sinuate before angles ; latter sub-basal, forming nearly 
rectangular projections; disc with anterior impression obsolete, middle 
line lightly impressed, basal sulcus moderate, faintly punctulate, not
