EUXESTUS MEDIONIGER sp. nov. 



Bhu'k; head, ti fascia at base of elytra, tlicir apical third and under-surfaee 

 more or less castaiicous ; clyli-al cpiplcin-ac, Ic^s, antennae, and i)alpi paler. 



Head with minute ])nnctures, a small fovea on each side of clypens. 

 Antennae short, basal joint large; club slightly wider than long. Prothorax at 

 ])ase almost thrice as wide as the median length, apex almost truncate, sides very 

 finely margined; ])nnctnres sparse and inconspicuous. Elytra with outlines 

 continuous Avith those of prothorax, widest at about basal fourth; punctures

Hah. New South Wales: Dorrigo (W. Heron) ; Western Australia: Manje- 

 mup (Dr. E. W. Ferguson). Type, I. 11783. 



This species, of which there are five specimens under examination, appears 

 almost to connect the described variety of E. ventralis with T. hivulneratus ; from 

 the former it is distinguished by the more conspicuous markings at base of elytra, 

 much finer punctures and almost truncated apex of prothorax, and from the latter 

 by its somewhat narrov/er and less couA-ex form, basal markings somewhat larger, 

 not blood-red, and almost touching the suture, and apex of elytra conspicuously 

 reddish. 



DIPHYLLUS OBSCURONOTATUS sp. nov. 



Black, elytra Avith two feebly defined spots before the middle ; legs, antennae 

 and palpi obscurely reddish. Densely clothed Avith short, suberect pubescence. 



Head with small and dense but sharply defined punctures. Antennae just 

 passing base of prothorax ; club two-jointed. Prothorax more than thrice as wide 

 as long, a deep stria near each side, and a much less distinct one near it. Elytra 

 Avith regular rows of rather large punctures, becoming smaller posteriorly; inter- 

 stices Avithout distinct punctures. Length, 2 mm. 



Ilah. Queensland: Cairns district (A. M. Lea). Type (unique), I. 11789. 



Structurally close to D. flavonotatus, but elytral markings consisting of tAVO 

 vague spots that could ho easily oA''erlooked, each is narroAV and extends across 

 thi'ee interstices; it is shorter and darker than the British D. Innntns, but with 

 markings approaching those of that species. 



DIPLOCOELUS PILINOTATUS sp. nov. 



Black, legs, antennae and palpi obscurely reddish. Densely clothed Avith 

 golden-grey pubescence, in places blackish; in addition with lines of short setae. 



Head Avith dense, partially concealed punctures. Antennae short; club 

 three-jointed, apical joint slightly longer and distinctly paler than the preceding
