Femora stout, strongly grooved, and lightly dentate, front 

 pair swollen in middle on one side; tibiae thin. Length, 

 2 mm. 



Hah. — Queensland: Cairns district, in rotting leaves at 

 Malanda (A. M. Lea). Type, I. 1329. 



A small, wide, and somewhat angular species, referred 

 to the genus with hesitation; the prothoracic tubercles being 

 a decidedly aberrant feature. The clothing varies from pale 

 stramineous to ochreous, and is denser and paler on the meta- 

 sternum and basal segments of abdomen than elsewhere. On 

 the elytra a large space on each side (the derm there deeply 

 stained with black) is conspicuously glabrous, the punctures 

 there are very distinct, but the striation is irregular; the 

 whole being somewhat reminiscent of Zenoporopterus mirus. 

 Each shoulder is also glabrous. From some directions the 

 femora appear to be thin, although they are really rather 

 largely dilated in the middle. 



Decilaus apicatus. Lea. 

 A specimen from Port Lincoln is probably a large and 

 partly abraded female of this species. It differs from the 

 types in being much larger (7 J mm.) with the tibial hooks 

 much smaller and blunt (probably worn down) ; its rostrum 

 is not quite so stout, is slightly less curved, and with 

 punctures nowhere concealed. The clothing is much sparser 

 than on the types (probably due to abrasion), and the 

 individual scales are somewhat narrower. 



Decilaus tibialis. Lea. 

 A male from Bell (Queensland) differs from the type in 

 being smaller (5 mm.), and with the paler scales more numer- 

 ous about base and apex of elytra. Three females, from the 

 Blue Mountains, have the elytra very similarly clothed. 



Cardiopterocis, n. g. 

 Head fairly large and evenly convex. Eyes rather small, 

 widely separated, coarsely faceted. Rostrum of moderate 

 length, rather wide, moderately curved. Antennae rather 

 stout; scape inserted nearer apex than base of rostrum, and 

 shorter than funicle; two basal joints of funicle rather long, 

 the others very short; club ovate. Prothorax lightly trans- 

 verse, sides strongly rounded, base almost truncate, apex pro- 

 duced. Scutellum small. Elytra elongate-cordate. Pectoral 

 canal deep and wide, terminated between middle coxae. Meso- 

 sternal receptacle level with coxae, walls thin and widely 

 U-shaped; open. Metasternum short; episterna represented
