316 NEW SPECIES OF AUSTRALIAN COLEOPTERA,

 Protliorax sliglitly narrowed in front, as long as head and rostrum 

 combined, without trace of median line. 8cutellum small, trans- 

 verse. Elytra parallel to near apex, suture slightly convex. 

 Sutures of intermediate abdominal segments very deep. Legs 

 short, anterior tibiae fossorial. Length 5, rostrum i; width 1-| mm. 

 Hah. —Clarence River, N.S.W. 



Numerous specimens taken from partlj^^ decayed trunks of the 

 large stinging tree ( Lapartea gic/oit). The great number of closely 

 allied genera described by Mr. Wollaston renders satisfactory 

 determination of any but those with atrongly marked features 

 somewhat difficult, and as this and the following species are at 

 least very close to Stereoborns (a species of which has already been 

 recorded from Australia) T ha^-e considered it advisable to place 

 them in that jrenus. 



>Stereoborus interstitialls, n 



sp 



Elongate-elliptic, subconvex, shining, glabrous. Black, antennae 

 and tarsi piceous. Head (except base) and rostrum densely 

 punctate, prothorax less densely; elytra striate-punctate, 

 punctures moderately large, approximate, interstices flat, feebly 

 but distinctly punctate; sterna with moderately large regular 

 punctures, smaller on abdomen. 



Head wide, eyes moderately distinct, a small .fo^'ea between 

 them; rostrum short, broad, feebl}^ dilating to apex, slightly 

 curved; antennne inserted nearer base than apex of rostrum; scape 

 curved, as long as funicle and club combined; club short, obovate. 

 Prothorax constricted near apex, widest behind middle, with 

 feeble trace of median line. Scutellum small, transverse. Elytra 

 decreasing almost from base to apex, striae deep at base, much 

 shallower towards apex, suture flat. Intermediate segments of 

 abdomen small, suture deep, apical segment feebly depressed in the 

 middle. Legs long, anterior tibiie subfossoi'ial. Length 4|, 

 rostrum ^; width li mm.
