Blackburn and Sloane (1921) thought that this species lacked an 
apical striole, but I think the striole is present but incorporated in the 
striation. The apex of the 3rd stria is deeply impressed for a short 
distance, arcuate, and with a puncture beside it on the inner side as 
in other species of the australis group, with which yarrensis agrees in 
most significant characters. 
Tachys pubifrons n. sp. 
With characters of australis group as given above. A rather slender 
member of group; reddish testaceous; shining, without (or nearly 
without) reticulate microsculpture above but head punctulate and 
setulose as described below. Plead .77 & .78 width prothorax; eyes 
moderate in size and prominence; antennae with segments 2 & 3 sub- 
equal, middle segments about i^X long as wide ; whole front de- 
pressed from behind level of eyes to clypeal suture, the depression 
including the frontal foveae, which are not individually distinct, and 
which do not extend to clypeus; front also irregularly punctulate and 
pubescent; mentum conspicuously 2-foveate at base. Prothorax cor- 
date, width/length 1.36 & 1.33; base/apex .99 & .97; base/head .87 
& .88 ; sides rounded anteriorily, strongly converging posteriorly, sinu- 
ate well before angles and then subparallel to angles (the sinuations 
occur about 1/7 of prothoracic length before angles) ; lateral margins 
poorly defined or partly obsolete; apex subtruncate with anterior 
angles rounded ; base at most slightly and broadly lobed, slightly 
sinuate toward sides ; basal angles sharply defined, approximately 
right ; disc with anterior transverse impression and middle line vague, 
basal transverse sulcus moderately impressed but interrupted at 
middle, coarsely punctate. Elytra with humeri rounded but promi- 
nent; margins behind humeri finely serrate and setulose; each elytron 
6-striate, with sutural stria entire, punctate anteriorly and groove-like 
posteriorly, and other striae formed of abbreviated rows of coarse 
punctures; stria 8 well impressed posteriorly, represented by a few 
punctures near middle, obsolete anteriorly; apical striole moderate, 
somewhat curved, ending about midway between suture and outer 
margin, with a coarse puncture on inner side well behind middle of 
its length; 3rd interval with 2 fixed punctures slightly before 1/3 
and 2/3 of elytral length. Inner wings fully developed. Secondary 
sexual characters as given for group. Measurements: length c. 2.5 
or slightly more ; width c. 1.0 mm. 
Holotype d (M. C. Z. Type No. 30330) and 7 paratypes all 
from Termed, southern New South Wales, October 1957, taken by 
myself. They were found under circumstances described under Tachys 
lutus (Darlington 1962, p. 120).
