these more finely but definitely punctate, the anal segment of cf 

 showing a strongly protruding forceps, hollowed on the inside. 

 Legs long, simple; tibiae straight, tarsi bilamellate on the anterior 

 four, unilamellate on the posterior tarsi, the latter with the basal 

 joint as long as the rest combined. 



Dimensions. — 19 x 6 mm. 



Habitat. — Cowra, Culcairn, Young, Forbes (New South Wales) 

 (Dr. E. W. Ferguson and the author). 



A common Metistete-like insect, from the western districts of 

 New South Wales, but winged and more elongate than in Metistete, 

 and may be recognised by its combination of convex rugose pro- 

 thorax, wide sulci and large punctures of the elytra, these scarcely 

 modified to extreme apex. 



Types in the author's coll. 



Hybrenia planata, n. sp. 



Elongate, parallel, depressed, brownish-black, oral organs, 

 antennae and legs red; upper surface (especially head and pro- 

 notum) with rather thick clothing of short, fine, upright red hair, 

 legs and abdomen still more densely pilose. Head and pronotum 

 coarsely punctate, the punctures round and large on the neck, base 

 of head and pronotum, smaller on epistoma and apical part of 

 pronotum, rather irregularly and not closely placed on the last. 

 Eyes large and approximate (about h mm. apart); labrum thickly 

 fringed, antennae shorter and stouter than usual, joint 3 evidently 

 longer than •!, 5-11 gradually shorter than preceding, and of nearly 

 the same thickness. Prothorax considerably wider than long, convex 

 and rounded in front, explanate behind, widest in front of middle, 

 apex advanced in the middle, anterior angles rounded and deflexed, 

 sides anteriorly well rounded, slightly sinuately converging behind 

 to the well-defined subrectangular posterior angles (these appearing 

 acute from above), base Insinuate, with large irregular depressions 

 near base. Scut ell u in widely triangular, rounded behind, finely 

 punctate. Elytra slightly wider than prothorax at base, and more 

 than three times as long, sides parallel, surface rather Hat, striate 

 punctate, each with a short scutellary and nine other rows of large 

 deep oval punctures, these larger towards sides and smaller towards 

 apex (about 20 punctures in the sixth row), intervals a little raised 

 and finely setose, Posternum rugose, metasternum coarsely, abdo- 

 men sparsely and more finely, punctate. Legs simple, tibiae 

 si raight.
