536 REVISION OF THE AMYCTERID^, 



obvious between the different varieties of the two species. From 

 P. mirabilis, it differs in its more regular elytral sculpture, and 

 and slightly longer forceps. 



PsALiDURA Coxi Macleay, loc. cit., p. 204. 



(J. Form large, robust, convex. Black, elytral granules black 

 or dull red; sparingly clothed with greyish scales; nigro-setose. 

 Head large, convex, overlapped by prothorax, rostral grooves as 

 in P. mirabilis; mandibles simple; gular horn present. Pro- 

 thorax(9 x 8 mm.) large, evenly rounded on sides, apex strongly 

 produced, collar-constriction faint; feebly depressed on disc, 

 granules rather coarser than in F. mirabilis and somewhat 

 flattened. Elytra(17 x 11 mm.) robust, rather feebly rounded on 

 sides, shoulders not prominent; disc regularly foveo-striate, fovese 

 small, separated by well defined transverse rugae; interstices 

 prominent, regular, all reaching to base, the fourth not quite 

 reaching apex; the third, fifth, and seventh more prominent, and 

 slightly more coarsely granulate. Anal excavation barely reach- 

 ing anterior margin, fossa very deep; fascicles widely separated, 

 situated within the excavation. Forceps somewhat larger than 

 in P. mirabilis, transversel}' widened at base; laminae moderately 

 long, almost touching; apex projecting backwards. Dimensions : 

 S, 25x 11; 9, 25 x 11mm. 



Ilab. — Mudgee, Coonabarabran (Macleay Museum); Wollon- 

 dilly River(Rainbow). 



Var. a. — Differs in being smaller((J, 22 x 9 mm.), but has the 

 same robust form and the regular elytral sculpture; the trans- 

 verse rugae are, however, smaller and not so prominent as in 

 typical specimens. 



Hab. — Tamworth(Musson), 



Var. B. — Slightly smaller than the type ((J, 24 x 9*5 mm.), and 

 of a somewhat flatter form; the elytral granules of a light red, 

 tending on the third and fifth interstices to be duplicated. 

 Transverse rugae low. 



Hab. — Blue Mountains, Wolgan Valley (H. J. Carter).
