Decilaus ordinakius, n. sp. 



Dark-brown or black; antennae and tarsi of a dingy-red. 

 Densely clothed with stout stramineous or muddy-grey scales, 

 sometimes sooty; but uniformly pale on under-surface of 

 body and of legs. 



Head with dense but comparatively small punctures. 

 Rostrum moderately long and rather thin, sides lightly in- 

 curved to middle, base considerably wider than apex, and 

 with coarse crowded punctures, elsewhere with smaller but 

 sharply-defined ones. Antennae thin, inserted slightly nearer 

 base than apex of rostrum ; scape scarcely as long as four 

 following joints combined; first joint of funicle almost as 

 long as three following combined, second as long as third and 

 fourth combined. Prothorax strongly transverse, sides 

 strongly rounded, apex less than half the width of base ; with 

 dense, round, deep, and fairly large, but partially-concealed 

 punctures. Elytra oblong-cordate, shoulders feebly rounded 

 and scarcely wider than prothorax; with rows of fairly large 

 punctures in distinct striae; interstices much wider than 

 seriate punctures, themselves with dense but more or less con- 

 cealed punctures. Mesosternal receptacle like half of an 

 elevated ring. Abdomen with large, round, deep punctures 

 on all segments, but largest of all on second, no segments 

 depressed. Femora, stout, rather strongly grooved, lightly 

 dentate. Length, 5J-6 mm. 



Hah. — Northern Territory (Blackburn's collection); 

 Queensland: Bloomfield River (C. French). Type, I. 1324. 



An ovate ordinary-looking species, but with dentate 

 femora. From the Tasmanian coryssopus (also so armed) it 

 differs in its much larger punctures, of both prothorax and 

 abdomen, and very different clothing. The scales are sparser 

 and larger on the prothorax than on the elytra. The first joint 

 ■of the funicle is unusually long. 



Decilaus bifurcatus, n. sp. 



(S . Black; antennae and tarsi red. Moderately densely 

 clothed with stout and feebly variegated, but more or less 

 dingy-brown scales, denser on legs than elsewhere. 



Head with crowded partially-concealed punctures. 

 Rostrum stout, sides lightly incurved to middle; with 

 moderately large punctures. Scape inserted two-fifths from 

 apex of rostrum, the length of four basal joints of funicle; 

 the two basal ones of these subequal in length. Prothorax 

 almost as long as wide, sides strongly rounded; with dense, 

 round, partially-concealed punctures, of rather small size (for 

 genus) ; with a very feeble median carina. Elytra rather
