In tbe male tbe bead does not appear to differ mucb from 

 tbat o£ tbe preceding species except tbat tbe clypeus is a little 

 blunter in front witb tbe impression on tbe bind part better 

 defined ; and tbat tbere is a strong conical born, wbicb is a 

 little inclined backward, is blunt at tbe apex, and rises from 

 iibe bead on its binder (perpendicular) side quite as mucb as 

 balf tbe lengtb of tbe clypeus, being fully twice as bigb as tbe 

 frontal elevation of tbe protborax. Tbe protborax is ratber 

 more tban balf again as wide as its lengtb down tbe middle ; 

 its base (wbicb is scarcely bisinuate) is more tban balf again 

 as wide as its front margin, wbicb is strongly bisinuate, and 

 raised in tbe middle into a small sbarp tubercle ; its frontal 

 impression is very little larger, but mucb deeper, tban tbat of 

 i:be preceding species ; its anterior angles are well defined, tbe 

 posterior rounded off ; its sides, viewed from above, appear 

 somewbat regularly, but not strongly, rounded ; tbe true 

 margin, viewed from tbe side, appears somewbat sickle-sbaped, 

 proceeding backward in a ratber straigbt direction for a little 

 distance from tbe anterior angle and tben making a strong 

 ■curve outward, wbicb is continued rigbt round to tbe base of 

 tbe protborax ; tbe surface is very finely and very sparingly 

 punctured, except in tbe frontal impression wbere tbe punctura- 

 ^ion is coarser and closer. Tbe puncturation of tbe scutellum 

 is coarse, and varies a good deal in closeness, some specimens 

 baving only about a dozen punctures on tbat organ mostly near 

 tbe base, otbers baving tbe same pretty closely punctured. 

 Tbe elytra are irregularly and not strongly striated, and are 

 marked witb rows of strong punctures, tbe punctures near tbe 

 suture and margin tending to lose tbeir serial arrangement. 

 Tbe pygidium is somewbat uniformly and strongly sculptured, 

 tbe sculpture being of sucb sort as to give tbe segment a 

 worm-eaten or corroded appearance. Tbe antennal club is as 

 long as tbe tborax, its widtb being about balf its lengtb. 



Tbe Soutb Australian Museum contains a specimen wbicb is 

 certainly, I tbink, a female Corynopliyllus. I refer it to tbis 

 particular species cbiefly on account of its possessing tbe same 

 peculiar colouration of tbe ventral segments, of wbicb tbe last 

 is black wbile tbe rest are red. It differs from tbe male in
