the base. The two examples before me are of very different size 

 but otherwise identical. They both seem to be males.

P. marmoratus, sp. nov. Brunneo-piceus, maculatim ochraceo-et 



albido-dense pubescens ; jDrothorace sat transverso, subtiliter 



sparsim granulato, indistincte ruguloso, spatiis 9 elevatis 



nitidis ornato, his pube densissima ochracea circumcinctis 



vel totis abditis, lateribus 2-tuberculatis et pone medium 



sinuatim convergentibus; elytris antice fortiter minus crebre 



postice leviter obscure punctulatis, postice spatiis parvis 



nitidis vix elevatis ornatis, apice oblique truncatis, truncatura 



externa spina valida armata ; antennis maris quam corpus 



sat longioribus, subtus piloso-ciliatis, articulo 3° quam 4°^ 



paullolongiori; pedibus albido-pubescentibus, maculis parvis 



nudis ornatis. Long., 111. ; lat., 3^1. 



A narrow elongate, somewhat frail-looking species for a 



Phacodes; extremely distinct by the dense ochraceous pubescence 



which forms conspicous markings on the head and prothorax. On 



the head it forms a ring round the eyes. The prothorax is very 



peculiarly sculptured; the hevigate spaces (which are very strongly 



elevated) are — a short longitudinal space in the middle near the 



base, and eight tubercles arranged in two transverse rows, both 



of which are arched hindward, so that the two inner tubercles of 



each row are nearer the base than the external ones, which are 



placed very near each other (one in front of, tlie other slightly 



behind, the middle). The external tubercles are on the margin, 



and interrupt the lateral edges, which converge somewhat sinuously 



behind them. The inner tubercles are elongate, and placed 



obliquely, and are much larger than the external ones ; they are 



more or less surrounded with a dense ochraceous pubescence, wliich 



gives them an ocellated appearance. The external tubercles 



are completely buried in dense ochraceous pubescence. The 



general surface of the prothorax is very even, but bears some 



small sparse granules. The elytra are nearly five times as long 



as the prothorax; they are very evenly marbled with whitish and 



ochreous pubescence in patches, these patches not taking any 



very defined form ; in some places, however, the pale pubescence 



forms rings round dark glabrous spots, especially along the 



lateral edge, and from a certain point of view there seems to be 



traceable a continuous zigzagged whitish line running from the 



middle of the margin obliquely to the suture, following the suture 



nearly to the apex, and then returning sinuously up the disc. 



The single strong sharp spine in the middle of the apex of the 



elytra is a notable character. Joints 3-5 of the antennae are 



spined. 



Australia ; I am doubtful of the exact habitat.
