538 REVISION OF THE AMYCTERID^, 



having more or legs fully costate elytra, and some of these are 

 closely allied, one of them being described in the present paper 

 as P. costipejinis. 



PsALiDURA VERRUCOSA Macleay, loc. cit., p. 203. 



^. Large, robust, convex. Head completely overhung by 

 prothorax; rostrum short, thick, basal grooves deep; mandibles 

 simple, a short gular horn present. Prothorax (8J x 8^ mm.) 

 angularly dilate on sides, median lobe strongly produced, coarsely 

 granulate, the granules being few in number, large, rounded, and 

 discrete. Elytra(18 x 11 mm.) evenly rounded on sides, the apex 

 feebly mucronate, humeral angles marked but not prominent, 

 disc longitudinally striate, not definitely foveate, interstices 

 coarsely granulate, granules elongate, feebly flattened, much finer 

 on the sutural interstice, on all the interstices continuous from 

 base to apex; fifth ventral segment widely and deeply excavate, 

 extending to the anterior margin; fossa deep, slightl}^ transverse; 

 fascicles small, situated far apart(4 mm.) within the excavation. 

 Forceps strong, transverse at base, laminae moderately large, 

 apices almost meeting and projecting angularly backwards. 

 Dimensions : (J, 27 x 11 mm.

The coarsely granulate prothorax and elytra will distinguish 

 this species from the other members of the armed-throat group, 

 or indeed from any of the genus. The specimens from New

 in not having all the elytral interstices evenly granulate, e.g.y 

 the granules on the second and sixth being wanting at the base, 

 and on the fourth only present on the middle; in my opinion 

 they represent only a variety.
