Lea — Australian Dung Beetles 377 



on sides tlmn elsewhere; with a feeble, obtusely pointed ridge in middle, about 

 one-fifth from apex; with dense and coarse juiuclures, the intervening spaces 

 with small punctures, a shagreened space without distinct punctures along middle 

 froni near the subapical ridge to base, and continued along each side at base, and 

 on the side to near the sublateral fovea, each of these rather narrow and deep. 

 Elytra witli luu-row, shining, geminate striae, with distant punctures, the int(n-- 

 stices finely shagreened and with small, distant, setiferous punctures. Meta- 

 sternum with irregularly distributed punctures of rather large size, with some 

 small ones scattered about. Apical segment of abdomen not narrowed in middle; 

 pygidium shagreened and feebly punctate. Length, 6-7 mm. 



Hah. Western Australia: Beverley (F. H. du Boulay), Mount Barker (S. 

 Macsorley). Type, L 3774. 



With the general appearance of the female of 0. adelaklae, but differs in the 

 interocular elevation, clypeal suture, prothorax with shagreened base and part of 

 median line, medio-frontal prominence, etc. ; in some respects it seems nearer to 

 the female of 0. Juiagi, but the elytra are without the conspicuous irregular series 

 of elongated subgranular elevations of that species. On the prothorax, head, and 

 elytral suture of the type the bronzy gloss is very conspicuous, but on the second 

 specimen it is but slightly in evidence.

Plate ix, fig. 76. 



9 Black, shining; antennae, palpi, tarsi, and front coxae reddish, club 

 paler; head (except clypeus) and prothorax coppery-green, elytra at base and 

 sides reddish. Under-surface and legs Avith whitish and reddish hairs, sides of 

 elytra with a few setae. 



Head with sides angularly dilated in middle, interocular ridge in the form 

 of a strong and almost evenly elevated carina ; between it and clypeal suture with 

 sharply defined punctures, of moderate size but not very dense, becoming denser 

 on sides. Clypeus with sides but feebly elevated, apex almost truncate, surface 

 densely transversely vermiculate; suture carinated and trisinuate, median sinus 

 very feebly arched, about three-fifths of the total. Eyes very narrow, facets 

 distinct. Prothorax large, sides strongly dilated, front angles (as seen from 

 directly above) almost rectangular, margins and gutters distinct on sides, less 

 distinct on apex and feeble at base; apical third with two large hollows, sur- 

 mounted by three obtuse processes; parts of the hollows with large and fairly 

 dense |)unctures,- somewhat similar punctures on sides, rest of the surface Avith 

 sparse and small punctures, and very minute ones; median line fairly distinct on 

 basal half, sublateral foveae rather large. Elytra with narrow striae containing
