its interavls irregularly connected, forming series of longi- 

 tudinal reticulations unequal in size. Prosternum and femora 

 closely granulose. A b domen rugose -punctate. Epipleurse wide 

 anteriorly, its fold forming an angle behind the shoulder, much 

 narrowed halfway. Tarsi and inside of tibiae clothed with 

 yellow hair, a short spine just perceptible at apex of tibiae, 

 intercoxal process, wide and nearly square. 



Near Dcedrosis, but with its final antennal joint even more 

 enlarged, a feature which distinguishes it from any of the 

 Australian Tenebrionidce known to me. In general facies, not 

 unlike some of the rougher, opaque species of Cardiothorax 

 (e.g., C. egerius, Pasc, C. mimus, Cart.). 



Macroperas antennalis, n. sp. 



Narrow elongate-elliptic; opaque-brown, antennae and 

 legs reddish; labrum, palpi, and tarsi pale-red. Head with 

 labrum and epistoma elongate, the latter straightly narrowing 

 from the canthus to the front, and concavely excised in 

 front; canthus scarcely raised or pro- 

 minent. Prothorax sub-cordate, about as 

 wide as long (4x4 mm.) ; apex bisinuate 

 (incurved at the middle and near the 

 angles) ; anterior angles acute and de- 

 flexed; sides widely rounded on anterior 

 half, then after a single crenulation 

 sinuately narrowed to base; posterior 

 angles acute and deflexed; sides and base 

 with narrow raised border without 

 channel; disc with rather wide central 

 depression and two shallow foveate de- 

 pressions on each side, the whole coarsely 

 and closely rugose. Elytra considerably 

 wider than the prothorax at base, narrowly 

 ovate or subparallel, faintly sinuate 

 towards apex; irregularly sculptured, the 

 central part more or less striate-punctate, 

 with about five lines of fairly large punc- 

 tures, the intervals raised and closely and 

 finely punctate ; the lateral half with 

 irregular reticulation, the two extreme 

 rows forming elongate foveae. Tarsi very 

 hairy, the posterior with basal and claw joint of nearly equal 

 length. Dimensions — 6i x 4 mm. 



Rah. — New South Wales: Moruya (G. W. Chessman). 



A single specimen, probably female, is very different 

 from any other genus, though allied to Dcedrosis and 

 Otrintus, with a unique sculpture difficult to describe. The
