 multo angustiori) ; corpore subtus sat nitido ; abdomine 

 latera versus strigato. Long., 7-8 1. : lat., 3J-4 1. 

 A somewhat nitid species notable for the extremely regu- 

 lar rows of conspicuous shining granules that adorn the alter- 

 nate interstices of its elytra. The emargination of the front 

 of its prothorax is decidedly wide and feeble as compared with 

 that of some Fterohelm. A specimen in my collection differs 

 from the type in being of narrower form, with the elytra a 

 trifle less nitid and the granules sm.aller. The difference is 

 perhaps sexual.

P. hullafus, Pasc. The hahitat of this species is curiously 

 given as "South Australia (Queensland)." The description 

 is much too scanty to be satisfactory (eg., no information as 

 to the antennal structure, or the width of the expianate mar- 

 gins of the different parts). The large size and elytral granu- 

 lation, however, distinguish it from most of the FterohelcEi, 

 and as T have in my collection specimens from Queensland 

 which agree very well with the description I have not much 

 hesitation in identifying them Avith it. I have also a Ptero- 

 helanis from South Australia, which is extremely close to 

 it and possibly furnishes the explanation of Pascoe's state- 

 ment of hahitat, though I doubt its being really identical 

 specifically, on' account of its being of still narrower form and 

 with somewhat different elytral granulation; but without see- 

 ing more specimens it would not be well to give it a separate 

 name. Champion attributes F. hullatus to Western Austra- 

 lia (Tr.E.S., Lond., 1894, p. 383), but I feel some doubt 

 as to Wiis reference being correct.
