to anterior margin of segment; preanal fossa transverse, posterior 

 edge with two lamellar projections between the bases of the 

 forceps; fascicles thin, close together(l mm.), situated within the 

 excavation; forceps long, feebly curved; laminae linear, obscured 

 by a fringe of yellow scales. Dimensions: (J, 20 x 8; 9,19 x 8mm. 



Hab. — Rockhampton, Dalveen, Queensland. Type in Macleay 

 Museum. 



I have carefully examined the type of T. incertus MacL, on 

 several occasions; it is, as conjectured by Macleay, a female 

 Psalidura. There are several species closely allied, which are 

 found at Rockhampton; and the females of these are hard to dis- 

 tinguish; but I a,m convinced of the correctness of the above 

 synonymy. From the description, I am of the opinion that T. 

 phrynos Pasc, will also prove to be synonymous. 



This species may be taken as the type of a large group of 

 species of Psalidura located in Queensland, and distinguished by 

 the possession of very long forceps, with laminae linear or appa- 

 rently absent. The present species differs from all, except P. 

 MitcheUi and P. cuneicaudata, in having the fascicles situated 

 well within the excavation; the other two are abundantly dis- 

 tinctive in other respects.

(J. Size large, form elliptical-ovate, sparingly clothed with 

 muddy-brown scales, nigro-setose. 



Head large, convex, inner rostral ridges most prominent at 

 base. Prothorax rounded on sides, moderately produced in front, 

 collar-constriction well marked, closely granulate, the granules 

 somewhat coarser than in P. forjiciilata. Elytra widely ampliate^ 

 width greatest just beyond middle; apex strongly mucronate, 

 base emarginate, shoulders not prominent, strife irregularly 

 crenulate, not definitely foveate; interstices irregular, rather 

 coarsely granulate in double series, except on the fourth and 

 sixth, granules umbilicated, setigerous. Metasternum convex, 

 rugulose. Anal excavation deep, extending almost to anterior 

 margin of segment; preanal fossa transverse, a narrow oblique
