deep transverse impression-. Femora very stout, front pair 

 strongly dentate ; middle tibiae more strongly dilated to near 

 apex than the others, hind ones with the apical third cut 

 away on upper-surface and excavated along same; four front 

 tarsi with basal joint distinctly inflated, the hind ones 

 decidedly longer than usual. Length ( d , 9 )j 5-6 mm. 



9-. Differs in having the hind tibiae at apex similar to 

 the middle pair, the palpi smaller and less securiform, and in 

 the abdomen and tarsi.

Allied to meyricki, but differs in the front femora of both 

 sexes being strongly dentate, hind tibiae of male very different 

 at ajDex, and apical fovea of abdomen more transverse. The 

 apical joint of each maxillary j^alpus of the male is wide and 

 truncate at the apex, much as on many Heteromera^ those of 

 the female are more ovate, but still truncate at apex ; the 

 labial palpi are smaller but otherwise much the same. The 

 specimens sent were either from Kalgoorlie or Beverley.

(S . Brassy or coppery or golden-bronze, head metallic- 

 green in front, coppery-green elsewhere ; labrum and append- 

 ages (tip of antennae and claws excepted) reddish or flavous. 

 Rather densely clothed with uniform, depressed, silken 

 pubescence, becoming white on under-surface. 



Head shagreened; punctures scarcely traceable; median 

 line distinct but very feebly impressed. Protliorax shagreened, 

 sides feebly rounded, front angles acute ; punctures minute and 

 scarcely visible before abrasion. Elytra suboblong ; punctures 

 dense and mostly small, frequently concealed before abrasion, 

 fairly large only about basal third, and nowhere transversely 

 confluent. Abdomen widely glabrous along middle, apical 

 segment with a conspicuous transverse impression, slightly 

 interrupted in middle. Front feinora strongly dentate ; basal 

 joint of four front tarsi somewhat inflated. Length ( d , 9 )> 

 5-6 mm. 



9 . Differs in the abdomen and tarsi.

 Ranges (Lea). Type, I. 3225. 



Although without any strikingly distinctive feature, this 

 species has yet a very unusual appearance, owing to the sides 

 of the prothorax being but very feebly rounded in the middle. 

 The under-surface varies from brassy to dark metallic-green. 

 Each side of the head, adjacent to the clypeus, has one or two
