dentate, slightly oliliciiie at the side>, the surfaoe smooth, shining, fulvous, entirely 

 impunctate ; scutellum small, triangular, raised jiosteriorly ; elj-tra cylindrical without 

 any depression, finely punctate-striate, the punctures distinct nearly to the apex, the 

 interstices flat, impunctate, fulvous, the extreme basal margin black, pygidium and 

 underside paler; jiro>ternum broader than long, its ))Osterior margin ^lightlv concave. 



Hah. Martapura (S.E. Borneo). 



Although the |)rosteruum in this sjiecies is not of the ty[)ical shape, the short 

 and dilated antennae seem to point to Melixanthim as the more suitable genus for its 

 reception ; the species may be known by the impimctate interstices of the elytra and 

 the colom- of the tiliiae and tarsi. 



Melixanthus timoreusis >\>. nov. 



Bluish black, the basal joints of the antennae fulvous; thorax closely strigose- 

 jmnctate at the sides, the disc nearly impunctate, elytra finely punctate-striate, the 

 interstices convex at the sides. 



Length 1 line. 



Head deeply inserted into the thorax, impimctate, eyes rather closely approached, 

 antennae short, the lower five joints fulvous, the sixth black, the other joints wanting; 

 thorax nearlj' twice as broad as long, strongly deflexed anteriorly, with an obsolete 

 oblique depression near the [losterior angles, the disc impressed with fine elongate 

 punctiu-es, which are crowded at the sides and deeper, forming longitudinal strigae, 

 the centre of the disc nearly devoid of punctures; scutellum narrowly elongate; 

 eh'tra cylindrical, the shoulders prominent, the surface finely imnctate-striate, the 

 sides more strongly punctured and the interstices costate ; legs black ; prosternuni 

 longer than broad, flat, strongly punctured. 



Hah. Timor. 



Distinct fi-om M. rainuttis by the elongate punctures of the thorax and the 

 entirel}- black colour. A single specimen. 



Melixanthus minutus sp. no\. 



Piceous below, greenish lihick alx>\e, the antennae (tlie apical joints excepted) 

 and the legs fulvous, thorax closely punctured, the sides strigose, elytra distinctly 

 punctate-striate, the interstices costate at the sides. 



Length i to J line. 



Kead greenish with a slight fulvous tint, distinctly punctured, lahrum fulvous, 

 antennae short, scarcely extending beyond the thorax, all the joints short, the la.st six 

 thickened, blackish, the others fulvous; thorax transverse, subcylindrical, the sides 

 rounded, the median lobe acutely produced, the surface more or less closely punctured, 

 the punctures more closely placed and larger at the sides, where the interstices are 

 more or less strigose ; scutellum very narrow and jwinted, elongate ; elytra cylindrical, 

 the punctures .strong and regular, closely approached, the interstices costate at the 

 sides, slightly convex at the disc ; legs short and .stout, fulvous ; prosternum -slightly 

 longer than broad, its apex truncate, its surface punctured, with an obsolete transverse 

 groove near the base, the colour more or less fuhous. 



Hah. Tenimber ; June, .Tuly. 



There is .some slight difference noticeable in the punctuation of the thorax and 

 the elytra between the thi'ee specimens before me, also in the colour of tiie antennae, 

 which are fulvous in one instance ; but I think this due to variation or to se.xual 

 diff'erence, as structural diflVrpncps s^eni to bo absent.
