rostrum; first joint of funicle slightly stouter and slightly- 

 shorter than second. Prothorax slightly longer than wide, 

 sides strongly rounded; apex produced and concave, with a 

 ridge bounding the concave portion ; subapical constriction 

 deep, irregular, and suddenly terminated at ridge; with four 

 rather feeble tubercles placed transversely at middle ; with 

 large, round, irregularly - distributed punctures ; median 

 carina absent except at extreme base, where it appears as 

 a scutellar lobe. Scutellum indistinct or absent. Elytra 

 narrow, much deeper than wide, scarcely wider than pro- 

 thorax; sides with large deep punctures on foveae, in places 

 connected so as to appear like zig-zag grooves; along middle 

 and on posterior declivity with much smaller punctures; pos- 

 terior declivity somewhat flattened, almost half the total 

 length of elytra, each side of its summit crowned with a large 

 round tubercle; third interstice at about basal fifth with a 

 rather small round tubercle, a still smaller one close behind 

 it, elsewhere with feeble tubercular swellings; suture and 

 tubercles with small, shining, squamiferous granules. Meso- 

 sternal rece/ptacle rather large at the base, walls of emargina- 

 tion thin and widely U-shaped. Legs long and thin; third 

 tarsal joint rather wide and deeply bilobed. Length, 6 mm. 



Hah. — New South Wales: Sydney (A. M. Lea). 



The type is probably a male, and is minus its abdomen 

 and hind legs, but it is so distinct that it has been described. 

 It is a narrow deep species, allied to parvidens and ornati- 

 collis, from both of which it may be distinguished by the large 

 tubercles overhanging the posterior declivity, the declivity 

 itself being unusually long and abrupt; not rounded as in 

 those species. Seen from the sides the elytra appear to have 

 a posterior slope for about half their total length, then an 

 undulated median space, and then a shorter and somewhat 

 concave basal slope. The eyes are quite as coarsely faceted 

 as in ornaticollis. As the middle femora extend to the apex 

 of elytra, the hind pair are certain to pass the same. 



POROPTERUS STENOGASTER, n. Sp. 



Densely clothed with more or less muddy-brown, setose 

 •scales or setae, becoming fasciculate on tubercles; rostrum in 

 front of antennae, and parts of under-surface, glabrous. 



Head with coarse but partially-concealed sculpture. 

 Eyes coarsely faceted. Rostrum moderately long, somewhat 

 suddenly inflated in front of antennae; with dense punctures, 

 clearly defined on apical third, larger but partially concealed 

 elsewhere. Antennae inserted one-third from apex of rostrum, 

 iirst joint of funicle stouter and slightly longer than second. 

 Prothorax slightly longer than wide, sides rounded in middle,
