seen to be rectangular. On the males there is usually a feeble 

 depression on the apical segment of the abdomen, but it is 

 very different to the large round fovea of the female. 

 Structurally and in colour, except that the legs are paler, it 

 is close to the preceding species, but is smaller, slightly 

 narrower, the prothorax with more distinct punctures, 

 somewhat different hind angles, and a shallow subbasal 

 depression, of which there is not a trace on that species. In 

 appearance it is very close to gymno2)terus, but the elytra 

 are not glabrous: it is also close to intonsus, but is more 

 oblong, due to the distinctly longer elytra, and the prothoracic 

 punctures are more distinct. In general appearance it is 

 also very close to the species commented upon as possibly 

 jmherulus, but is at once distinguished by the eyes of the 

 male being considerably smaller and more distant; on that 

 species the distance between them at their nearest, is scarcely 

 more than the length of the white-clothed canthus of each 

 eye; on the present species the space is fully twice the length 

 of each canthus, the punctures on the prothorax are also a 

 trifle larger and more evenly distributed. 



A female, from Morgan, has the club of the antennae, 

 the tarsi, and the hind femora more or less deeply infuscated.. 

 A female, from Oodnadatta, is rather larger (3 '25 mm) than 

 usual, and the depression on the prothorax is more vague 

 than on most specimens.

cf . Coppery-bronze, with a slight greenish gloss;; 

 labrum, antennae, palpi, and legs reddish; club, claw-joints, 

 and claws blackish or infuscated. Head, prothorax, and 

 ander-surface with rather dense, white pubescence, becoming 

 sparser on legs. 



Head with fairly numerous but not very large punctures, 

 becoming more crowded on clypeus. Eyes widely separated. 

 Prothoray not twice as wide as the median length, sides 

 strongly rounded; punctures small and numerous, but not 

 crowded. Elytra rather strongly narrowed posteriorly; with 

 rows of large, deep punctures, seriate only about base and 

 middle, set in deep striae at the sides and apex; interstices 

 impunctate. Legs moderately long and very thick. Length 

 (d, 9), 3-3-75 mm. 



9 • Differs in having somewhat smaller head and 

 antennae, prothorax at base twice as wide as the medium, 

 length, elytra less narrowed posteriorly, legs shorter and much 

 less thick, and in the abdomen,
