Densely clothed with short brownish pubescence, becoming 

 greyish on scutellum, under-surface, and legs. 



Head with basal portion curvilinearly triangular, and 

 with small dense punctures. Eyes large, almost touching both 

 above and below. Antennae with first joint stout, almost as 

 long as three following combined, second and third moder- 

 ately, fourth strongly transverse, fifth with a short produced 

 portion on one side, sixth to tenth each with a long ramus, 

 eleventh as long as ramus of tenth. Prothorax with sides 

 strongly diminishing in width to apex, which is not half the 

 width of base, median line faint at base and apex, but con- 

 spicuous and somewhat dilated in middle ; punctures as on 

 head. Elytra slightly wider than prothorax, sides regularly 

 decreasing in width posteriorly, each with four feeble longi- 

 tudinal elevations. Length, 10-13 mm. 



9 . Differs in being rather more robust, abdomen larger, 

 legs somewhat shorter, and antennae with none of the joints 

 transverse, the third almost twice the length of second and 

 distinctly longer than fourth, fifth slightly shorter than fourth 

 but at tip slightly wider, sixth to tenth strongly serrated, 

 eleventh distinctly longer than tenth, and with a slight pro- 

 jection at its middle.

In general appearance strikingly close to occidental is, but 

 the long rami of the antennae start on the sixth joint instead 

 of on the fifth. Sometimes the whole of the under-surface 

 and legs are castaneous. The only female before me has two 

 feeble depressions on the disc of the pronotum, but from some 

 directions they appear quite conspicuous, owing to their 

 clothing being slightly different in disposition to that on the 

 adjacent parts ; on some of the males there are slight traces 

 of these depressions. Two specimens from Coolgardie and 

 Nullabor Plains (from the Blackburn collection) evidently 

 belong to this species, but their antennae are broken off short.

<3 . Black, claws and flabellate joints of antennae red- 

 dish. Densely and uniformly clothed on upper-surface with 

 brown pubescence, becoming brownish-grey on under- 

 surface and legs. 



Head with basal portion strongly convex and curvilinearly 

 triangular. Eyes large and rather close together. Antennae 

 with first joint stout, as long as the three following combined, 

 second transverse and longer than third, third slightly longer 

 than fourth, the latter fullv twice as wide as lone:, fifth with
