impressions, but a short longitudinal sulcate ; the palpi are brown ; 

 the antennae black, with the external base of the first three articles 

 of a rather dark brown ; the tarsi have some long brown hair ; 

 palpi of a dark brown." 



" Mountains of Victoria." 



From the remark above, "the tarsi have some long brown hair," 

 it is evident that de Castelnau's only specimen was the 9. From 

 M. Putzeys' notice of P. nigricornis, I take the following : — " Le 

 rebord [du corselet] marginal s'elargit un pen dans sa moitie 

 infei-ieure ; il se prolonge nettement au milieu de la base.— Les 

 segmens 3-6 de Tabdomen portent de chaque cote une fossette 

 arrondie et profonde." He gives the measurements as — length ] 4, 

 elytra 8, breadth G mm. 



Promecodehus nigellus, n. sp. 



Black, shining, legs black, tarsi and antennte of a clear brown, 

 palpi piceous. Head smooth, the frontal fovea? faint, extending 

 behind the clypeal suture (this lightly impressed, and only dis- 

 tinct between the fovese) ; the transverse impression behind the eyes 

 not extending across the vertex ; eyes prominent ; post-ocular 

 prominences moderate. Prothorax subcordate, a little broader 

 than long (3^ x 3^7 mm.), convex, slightly declivous behind, the 

 basal part defined by a transverse impression ; sides rounded, 

 broadest about the middle, obliquely narrowed to the base ; 

 marginal border fine, not sinuate before the basal angles, dis- 

 tinct and entire on the base ; the basal angles almost right angles ; 

 median line strongly impressed, not reaching the anterior margin 

 but terminating in a transverse impression in front, extending to 

 the base behind. Elytra oval (6| x 4 mm.), convex, equally 

 rounded in front and behind, striate, the stria next the suture 

 complete, the three next marked on the anterior part but becom- 

 ing obsolete towards the apex ; the sides smooth to the eye (faint 

 stripe being discernible under a lens). Four last ventral seg- 

 ments with a deep round fovea on each side. Male with the thighs 

 dilatate in the middle ; the anterior tarsi with four first joints 

 spongiose below, the last joint small ; the middle tarsi with two 

 first joints spongiose below.
