Lea — Australian Dung Beetles 361 



EPILISSUS USTULATUS Lansb. 



Five specimens, from Cairns and the Little Mulgrave River, probably belong- 

 to this species ; four of them have the shoulders conspicuously paler than the 

 adjacent parts ; of these four, two have the apical sides and epipleurae also pale, 

 of these two, one is mostly blackish, the other mostly castaneous ; the fifth speci- 

 men has the entire upper-surface dark piceous-browui. They all differ from the 

 description, however, in having the club of the antennae partly infuscated, and 

 the front tibiae acutely bidentate outwardly, but there is a blunt tooth at the 

 inner apex. If correctly identified the species should be transferred to Panehis. 



PANELUS BIDENTATUS Wilson. 



Three specimens, taken from rotting leaves at Ourimbah and National Park 

 (New South Wales), and Mount Tambourine (Queensland), structurally agree 

 with the type, but they all differ somewhat in colour. On the National Park 

 specimen the pale humeral and subapical spots on each elytron are enlarged and 

 connected along the side ; on the Ourimbah one the pale parts of each elytron are 

 further enlarged to cover most of the surface, leaving only a moderate infuscation 

 about the scutellum, the head and prothorax are also almost entirely pale; on the 

 Mount Tambourine specimen the prothorax and elytra are entirely dark. 



PANELUS PISONIAE sp. nov. 



Pale flavo-castaneous, highly polished, extreme base and suture of elytra very 

 narrowly black, plub infuscated. 



Head gently convex and with minute punctures between eyes, a subtriangular 

 projection on each side of a deep medioapical notch. Prothorax more than twice 

 as wide as the median length, sides on basal two-thirds subparallel, then oblique 

 to apex, where the angles are acute ; punctures minute, but a row of slightly larger 

 ones at extreme base. Elytra closely applied to prothorax; striae faintly im- 

 pressed, interstices with minute punctures. Front tibiae bidentate externally, 

 the apical tooth larger than the other. Length, 2-2-5 mm. 



Hah. Northern Queensland (Blackburn's collection). Cairns district, taken 

 in abundance from stickj^ seeds of Pisonia hrunoniana (F. P. Dodd). Type, 

 I. 15432. 



The pale colour and feeble elytral striation at once distinguish this species 

 from P. pygmaeus; the persistently smaller size and paler colour from P. 

 hidentatus. On most specimens there appears to be a large infuscated spot near 

 the apex of each elytron, but this is entirely due to the apical fold of the wings 

 showing through. On most specimens the elytral striae are very feeble and 

 traceable only near base, but on some of the smaller ones they are fairly distinct, 

 and contain small, distant punctures.
