extension backwards and upwards. Eyes subrotundate. Pro- 

 thorax (4 x 5 mm.) rounded, disc convex, with a sinuous impres- 

 sion across in front of base, and a feebler one behind apex, abso- 

 lutely laevigate, with minute scattered punctures. Elytra(llx 

 6-5 mm.) ovate, apex moderately produced, mucronate; humeral 

 angles with a prominent out-turned nodule; foveate in double series 

 in two central stria?, in single in lateral stria; foveae large, open, 

 communicating irregularly, and separated by plications often in- 

 complete; as a rule, foveae situated side by side are not separated 

 off; second interstice most prominent, eostiform, and strongly 

 undulating in outline; sides with smaller and more regular foveae. 

 Beneath, fifth segment not excavate, but with a feeble oblong 

 impression at apex. Femora not spined. 



Q. Similar, but rather more ovate, and convex beneath. Dimen- 

 sions : (J. 17 x 6-5; £.19 X 8 mm. 



Hab. — Victoria. 



Readily distinguished by its laevigate prothorax; its relationship

£. Size small, elongate-ovate. Black, opaque; depressions with

Head convex, forehead very gently concave between ends of ros- 

 tral ridges. Rostrum short, deeply excavate; external ridges rather 

 strongly convergent, extending on to forehead, profile of head and 

 rostrum straight; internal ridges long, extending from near apex, 

 strongly convergent ; median area narrow, depressed ; lateral sulci 

 long, deep. Scrobes with a feeble prolongation in front of eye. 

 Eyes subrotundate. Prothorax (3-5 x 4*5 mm.) rather strongly 

 rounded, orbicular, apex truncate, with very feeble postocular 

 sinuosity ; disc closely and evenly set with fine, somewhat depressed, 

 granules: sides similarly granulate. Elytra ( 1 x 6'5 mm.) ovate, 

 apex moderately produced, and conjointly mucronate; base sub- 

 truncate; humeral angles not produced but marked by a slight
