II ah. Queensland: Brisbane, in November (H. Hacker). Type, in Queens- 

 land Museum. 



At first glance apparently close to some forms of 0. haagi (a species in which 

 the interoeular horn is very variable), but prothorax without luedio-frontal 

 projections, and elytra without granules or small tubercles on the interstices; the 

 prothorax and elytra are sculptured much as on 0. adelaidae. The process on 

 the head of the type rises abruptly vertical, and with almo.st parallel sides, for a 

 height about equal to half the distance betAveen the eyes, its ends are then 

 continued as narrow horns for rather more than one-third of the total height; 

 there is a small node on its back part. From the sides the prothorax and elytra 

 may be seen to have very short setae, but they are scarcely visilile from most 

 directions. 



ONTHOPHAGUS COMPOSITUS sp. nov. 



S Black, most parts with a slight bronzy gloss; antennae (clul) blackish), 

 palpi, and tarsi of a more or less dingy red. ITnder-surface and legs with 

 rusty-red hairs. 



Head with crowded and sharply defined punctures of moderate size ; a small 

 conical horn near each e.ve. Clypeus with sides moderately elevated, apex 

 obtusely notched, suture trisinuate and carinated throughout, median sinus 

 almost straight and about three-fifths of the total. Eyes very narrow and with 

 distinct facets. Prothorax with sides strongly rounded, front angles produced 

 and acute, lateral margins narrow, front ones. still narrower, basal absent; front 

 somewhat gibbous ; median line vaguely traceable near apex and at ])ase ; punc- 

 tures and elytra as described in preceding species. Metasternum with dense, 

 asperate punctures on sides, small, mixed with large ones, elsewhere. Abdomen 

 with apical segment strongly narrowed in middle ; pygiclium shagreened and with 

 dense punctures. Length, 7 mm. 



Hah. Queensland: Stanthorpe (von Weildt). Type in Queensland 

 Museum. 



The sculpture of the prothorax and elytra approaches that of 0. adelaidae 

 and 0. phoenicocerus, but the head is very different; the colour and cephalic 

 horns are somewhat as in 0. granicollis, but the prothorax is nongranulate ; 0. 

 spissicollis has more rugosely sculptured prothorax and very different clypeus. 

 On the sides of the elytra there are some very short setae, and none elsewhere, but 

 tbe type may be partly abraded. 



ONTHOPHAGUS SQUALIDUS sp. nov. 



$ Black, in parts with a faint bronzy gloss; antennae, palpi, aud tar.si 

 reddish. Under-surface and legs sparsely clothed.
