one, but with normal tibiae ; unfortunately the only specimen 

 of it before me is headless. In the table previously given by 

 me the present species should be placed with taut ilia and 

 suhfasciata, from which it is readily distinguished by its much 

 larger size and curious tibife. 



POROPTERUS PRODIGUS, PaSC. 



There is absolutely nothing in the description of this 

 species to distinguish it from the common conifer, Er. (which 

 occurs in Victoria and New South Wales as well as in Tas- 

 mania), and (in Proc. Linn. Soc, New South Wales, 1897, 

 p. 506) I recorded it as a synonym of that species. At the 

 time I was unaware that the Rev. T. Blackburn had also 

 {I. c, 1889, p. 1273) regarded it as a synonym. 



There is now before me a specimen from Mr. Hacker (who 

 informs me that he has two other identical specimens from 

 Mount Tambourine, in Queensland) which is probably fro- 

 digus, but it differs from conifer in having the large conical 

 tubercles on the elytra larger and distinctly diverging, in- 

 stead of almost parallel. It is certainly a form well deserv- 

 ing of a varietal name, although it does not appear to be 

 really distinct. 



At a glance the specimen looks like some forms of 

 Jeheli, but the large elytral tubercles are not at the apex 

 itself (although from above they appear to be there), but 

 some distance above it, as can be readily seen from the sides. 



Although this specimen agrees exactly with Pascoe's de- 

 scription, there is still the possibility that his iJrodigiis was 

 the ordiiiary form of conifer. 



PoROPTERUS SULCIVENTRIS, n. Sp. 



Black : antennae and tarsi reddish. Clothed with black 

 upright scales, and with small spots of ochreous or fiavous 

 scales. 



Rostrum, short and stout ; with coarse but more or less 

 concealed punctures, even towards the apex. Antennae in- 

 serted slightly nearer apex than base of rostrum ; scape 

 shorter and stouter than usual : first joint of funicle slightly 

 stouter and shorter than second, second as long as third and 

 fourth combined, third to seventh transverse. Prothorar. 

 rather flat, slightly longer than wide, basal two-thirds par- 

 allel-sided, then rather strongly narrowed to apex ; with 

 large, round, somewhat irregularly distributed punctures. 

 Sciitelhim absent. Mytra not thrice the length of prothorax 

 and at base scarcely wider, shoulders produced, suddenly, but 

 not largely dilated near the base, and then almost parallel- 

 sided to beyond their middle, then suddenly narrowed, but
