552 REVISION OF THE AMYCTERID^, 



verse ridges running up on either side on to the interstices; 

 interstices four in number, costiform, becoming granulate on 

 declivity, setigerous in single series; sutural interstice thickened 

 and outturned at base, elsewhere represented by a fine row of 

 granules; third interstice humeral; sides irregularly granulate. 

 Metasternum feebly concave, anterior prolongation rounded. 

 Fifth ventral segment rather shallowly excavate, excavation 

 reaching to anterior margin only in middle line, the margins of 

 the excavation not well defined, preanal fossa present but not 

 sharpl}'" marked off from rest of excavation; posterior border 

 fringed across middle line; fascicles moderately close(l mm.), 

 thin, long, and black, situated on edge of excavation. Forceps 

 extremely short, thick, not meeting at apex, and hardly produced 

 beyond dorsal tergite, laminae narrow, present along inner sides. 

 Apical tergite projecting between forceps, coarsely punctate. 

 Legs densely clothed with black setse, longer and stouter on under 

 side, tarsal joints not dilated as in P. amplicollis. 



9. Head as in (J, mandibles simple; prothorax subquadrate 

 (5x6 mm.), not depressed in centre, with median line fainter; 

 granules somewhat coarser than in ^, and not abraded; elytra 

 (11x8 mm.) more gradually rounded from behind middle to apex; 

 interstices showing greater tendency to granularity, the trans- 

 verse ridges extending across the sulci; undersurfaca slightly 

 convex; lifth ventral segment large, not excavate, with a shallow 

 impunctate fovea in centre. Dimensions: fj, 18 x 8; <^,\^ x 8mm. 



HQh.- — New South Wales, Blue Mountains (Blackheath, 

 Katoomba, Leura). 



A short, subquadrate species, belonging, at first sight, to 

 Talaurinus, but with all the characters of a true Psalidura. 

 The forceps are peculiar, in being very short and stumpy, and 

 not meeting at the apex. It is most closely allied to P. ampli- 

 collis, from which its smaller size, and different anal appendages 

 will separate it. 



Psalidura elongata Macleay, loc. cit, p. 207. 



^. Densely clothed with greyish scales, varying to brown, setae 

 dark brown, granules not clothed, unisetigerous, anal hair reddish.
