regular than and slightly in advance of the others. Scutel- 

 lum absent. Elytra not much wider than prothorax, and 

 almost thrice the length along suture ; third interstice with 

 a rather large tubercle at summit of posterior declivity, a 

 small one between it and apex ; fifth interstice with three 

 tubercles, one at basal fifth, the others near the large one on 

 third ; seventh interstice with a conical and laterally-project- 

 ing tubercle at basal fourth, and a small one about the 

 middle ; with very large punctures, regular only on sides. 

 Under surface with small dense and normally-concealed punc- 

 tures. Leys rather long; hind femora just passing apex of 

 elytra ; third tarsal joint not much wider than second, and 

 obtusely bilobed. Length, 15 mm. 



Hab. — Queensland: Mount Tambourine (R. Illidge). 



In appearance like a rather small and narrow specimen 

 of rub us, but elytra without small conical tubercles at the 

 apex, the subsutural row of tubercles different, and the tarsi 

 not truly linear, the third joint being slightly bilobed, 

 although very little wider than the second. Intermedius and 

 idohis each have a pair of conjoined tubercles near summit 

 of posterior declivity ; verres has the elytral tubercles dif- 

 ferent and the prothorax not conspicuously keeled. It is 

 not likely to be confused with any other species. 



On each elytron there is an elongated fascicle on the 

 third interstice, extending from the base to near the middle, 

 but slightly curved ; most of the scales of which it is com- 

 posed are darker than the others. On the type (which is 

 probably a male) there are two shining granules on each 

 elytron near the base — one at the base of the long fascicle, 

 and one half-way between it and the suture. 



Decilaus seriatopunctatus, n. sp. 



Black ; rostrum, and legs (and sometimes part of the 

 elytra) dull-reddish-brown; antennae and tarsi paler. Clothed 

 with long setose scales varying from snowy- white to black. 



Head with dense punctures, fairly large in front but 

 much smaller posteriorly. Rostrum lightly but distinctly 

 curved ; with numerous punctures concealed only at extreme 

 base. Scape rather thin, inserted about two-fifths from apex 

 of rostrum, not much shorter than funicle ; club very briefly 

 ovate. Prothorax about once and one-third as wide as long ; 

 widest near base, thence strongly diminishing in width to 

 apex ; with dense, round, deep, and fairly large punctures. 

 Elytra subcordate, base almost truncate ; with series of large 

 suboblong punctures, the interstices scarcely raised. Two 

 basal segments of abdomen with large and fairly dense punc- 

 tures, apical segment with denser and smaller ones. Femora 

 stout. Length, l|-2^ mm.
