short, base trisinuate; with rows of large punctures in light 

 striae; interstices on basal half the width of, or narrower 

 than, seriate punctures, but becoming wider posteriorly. 

 Mesosternal receptacle distinctly raised ; emargination widely 

 transverse. Abdomen with small but rather dense partially- 

 concealed punctures ; first segment obliquely sulcate on each 

 side of base, and with a feeble tubercle on each side of middle. 

 Femora stout, strongly grooved, and feebly dentate; hind 

 tibiae with apical hook bifid; third tarsal joint wide and 

 deeply bilobed. Length, 6-7 mm. 



9 . Differs in having the rostrum somewhat longer and 

 thinner, with smaller punctures, abdomen non-tuberculate 

 and hind tibiae with apical hook simple. 



Hah. — Victoria: Alps, Mount Hotham, Fern Tree Gully 

 (Blackburn's collection). Type, I. 1325. 



In general appearance fairly close to tibialis, and with 

 very similar hind tibiae, but clothing of under-surface of male 

 very different. The clothing there is somewhat paler than 

 that of the upper-surface, but is otherwise very little different. 

 The teeth are fairly distinct on the front femora, but scarcely 

 traceable on the others. 



Dectt.aus oosomus, n. sp. 



Black : antennas and tarsi of a rather bright-red. Clothing 

 not very dense. 



Head with crowded, partially-concealed punctures. Ros- 

 trum moderately stout, sides lightly incurA^ed to middle; with 

 coarse punctures, irregularly grooved behind antennas. 

 Antennas as described in preceding species. Profliorax rather 

 strongly transverse, sides strongly rounded, ba-se truncate : 

 with dense, large, round, deep punctures, becoming much 

 smaller at apex. Elytra short, sides strongly rounded, extreme 

 base no wider than base of prothorax ; with rows of large, 

 round, deep punctures, in very feeble striae; interstices nar- 

 rower than striae, even posteriorly. Mesosternal receptacle 

 strongly elevated, like half of a ring. Abdomen with irregular 

 punctures. Femora stout, moderately grooved. Length, 

 3|-41 mm. 



Hah. — South Australia: Port Lincoln (Blackburn's col- 

 lection). Type, I. 1326. 



A short species, with large punctures and conspicuously- 

 rounded elytra. In general appearance it is something like 

 moluris, but the elytral punctures are much larger and less 

 oblong, etc. The prothoracic punctures are about the size of 

 those of cnniculosus, but the elytral ones are much larger and 

 differently shaped. The abdomen has large punctures on the 

 first segment about the base and at its suture with the second,
