summit of posterior declivity; with series of rather large, round, 

 distant punctures, that become smaller and more distanton the sides, 

 and very small posteriorly. Basal segment of abdomen with large 

 punctures, largest behind coxas; apical segment with dense and 

 rather large punctures. Length 6-9 1/2 mill. 



Hab.: N. S. Wales: Clarence River (Belgian Museum); Tweed and 

 Richmond River (Macleay Museum, R. Helms and A. M. Lea); 

 Burrawang (T.G.Sloane); Queensland: Brisbane (Belgian Museum). 



Specimens may be obtained in abundance in the ((big scrub)) of 

 the Tweed and. Richmond Rivers. The two median excavations of the 

 head are usually deep and very distinct. The sculpture has been 

 described from abraded specimens. 



9. Differs in having only the basal third of the rostrum coarsely 

 punctate, the apical two-thirds highly polished, finely punctate and 

 without ridges. The antenna3 also are inserted nearer the base. 



CYGLOPOROPTERUS n. g. 



Head small and partly concealed. Eyes ovate, widely separated, 

 rather coarsely faceted. Rostrum long and thin, moderately curved. 

 Antennoi slender; scape inserted much closer to apex than base of 

 rostrum, longer than funicle and almost as long as funicle and club 

 combined; two basal joints of funicle elongate; club ovate, sub- 

 continuous with funicle. Vrothorax transverse, base sides and apex 

 rounded, constriction scarcely traceable, apex somewhat produced; 

 ocular lobes obtuse. Scutellum absent. Elytra brietly subovate, 

 outline continuous with that of prothorax. Pectoral canal not very 

 deep, its termination not defined. Mesosternal receptacle depressed, 

 strongly transverse, excavated except at sides; open. Metasternum 

 much shorter than the following segment; episterna not traceable 

 except for a small anterior triangle. Abdomen moderately large, 

 sutures (except that between first and second in middle, which, 

 however, is very distinct) deep and distinct; first segment as long 

 as the two following combined, intercoxal process very wide; 

 combined length of third and fourth slightly more than that of 

 second or fifth. Legs long and moderately thin; front coxse slightly 

 encroaching on canal, middle widely, the hind very widely separated 

 and at sides touching elytra; femora feebly grooved and edentate, 

 hind pair passing elytra; tibife scarcely compressed, moderately 

 curved; tarsi shorter than tibife, third joint wide and deeply 

 bilobed, fourth rather long and thin; claws thin. Subglobose,

A remarkable genus, the position of which is doubtful. The
