Promecoderus SEMISTRIATUS. 



P. semistriatus, Casteln. I.e. p. 168; Putz. Eevis. 1873, p. 328. 



I ascribe this name to a species that I find in the Macleay 

 collection labelled P. semistriatus. 



It hardly agrees with M.Putzeys' description of P. semistriatus 

 in his Revision, being a smaller and lighter insect. M. Putzeys 

 redescribed j the type specimens (9) of Count de Castelnau. 

 His description seems more applicable to P. oUvaceus, Macl., 

 than to the present species ; however, even should P. olivaceus 

 prove to extend to the eastern side of the Blue ^Mountains, 

 I think it will tend less to confusion to apply de Castelnau's name 

 to the present species, which differs from P. olivaceus, though 

 there certainly does not appear room for a tlurd species between 

 them. 



The following is the description of a specimen {^) in my 

 collection received from Mr. F. A. A. Skuse as coming from 

 Woronora, 1 2 miles south of Sydney. 



$ Shining, prothorax blackish green, elytra bronzy olive ; 

 under surface piceous black, tibise, tarsi, and parts of mouth piceous. 

 Head smooth ; clypeus with a setigerous puncture on each side ; 

 forehead lightly impressed behind the clypeal punctures ; vertex 

 with a very strong broad transverse impression ; eyes rather 

 prominent ; post-ocular prominences less protuberant than the 

 eyes, two-thirds the size ; antennre long, slender. Prothorax 

 cordate, (3| x 3^ mm.), the disc flattened, not declivous behind, 

 a transverse linear impression a little in front of the base, lightly 

 rounded on the sides, very little narrowed to the anterior angles ; 

 marginal border narrow, not sinuate in front of the basal angles, 

 not reaching the middle of the base ; basal angles well defined, 

 almost right angles ; median line deeply impressed. (I have seen 

 three male specimens, and in all there are two lightly marked 

 oblique short linear impressions on the posterior half of the disc, 

 one on each side of the median line ; the only female specimen I 

 have seen is without these striolse). Elytra oval (6^ x 4;^ mm.), 

 depressed, narrowed to the shoulders, striate, a smooth space near
