foveo-striate, foveas deep and regular, slightly transverse; inter- 

 stices costiform, first only costate at extreme base; second, thirds 

 fifth, and seventh prominent, costate, somewhat crenulate; fourth 

 and sixth interruptedly granulate, the granules rather fine and 

 in single series, traceable throughout except on declivity. Sides 

 regularly foveo-striate. Metasternum feebly concave. Fifth 

 ventral segment widely and deeply excavate, extending back to 

 the anterior margin; preanal fossa deep; fascicles large, situated 

 far apart(3'5 mm.), within the excavation. Forceps moderately 

 long, feebly arcuate, not markedly transverse at base; laminae 

 rather large, directed inwards and just meeting at apex, project- 

 ing backwards. Dimensions : ^J, 23 x 10 mm. 



Hah. — Queensland : Brisbane(R. Illidge). 



Most nearly allied to P. canceUata, but abundantly distinct in 

 having all the elytral interstices present in their entirety, and in 

 having the second interstice fully costate. From all other 

 described species of this group, the costate elytra will distinguish 

 it. The prothoracic granulation is finer than in any other of the 

 P.-mirah ilis-grouTp. 



PsALiDURA MiKACULA Maclcay, loc. ciL, p. 205. 



A thoroughly distinct species, most closely related to P. 

 apjjroximata. Head and rostrum very large, mandibular horns 

 strong and divergent. Prothorax (6*5 x 75 mm.) without median 

 lobe, closely, somewhat obsoletely, granulate, median impression 

 rather faint. Elytra(16 x 10 mm.) ovoid, shoulders not produced, 

 apex strongly flanged and mucronate; striate, shallowly foveate, 

 interstices costate, sutural prominent at base, outturned to join 

 third; third and fifth prominent and reaching to base; second 

 not reaching base; fourth not prominent, not extending beyond 

 declivity; sixth and seventh not so prominent. Ventral excava- 

 tion deep in ^, reaching anterior margin of fifth segment; pre- 

 anal fossa transverse, a prominent intermediate ridge running 

 from posterior border to end in front of fossa, but not continuous 

 across middle line; fascicles small, very close together, situated 

 within excavation. Forceps long, curved, inner surfaces looking
