first joint slightly longer than second. J^rothorar slightly trans- 
verse, sides rounded, constriction continued across summit, 
across middle a series of four moderately large and very dis- 
tinct tubercles, a subobsolete one on each side of apex : with 
rather numerous large, glossy granules : median line witliout 
granules, but with a feeble ridge anteriorly. SotfeJh/n) sub- 
triangular, distinct Elytra ovate, about thrice the length 
and at widest about once and one-half the width of pio- 
thorax : interstices with numerous small and moderately 
large glossy granules, and with about five or six small 
tubercles on each side : each side at summit of posterior decli- 
vity with a large subcorneal tubercle ; each side of apex with a 
moderately distinct one. Abdomen with second-fourth seg- 
ments scarcely depressed, and at a glance appearing almost 
equal in length, but the second encroaches on the first- /ycv-s 
long and rather thin : posterior femora extending to apex of 
elytra; third tarsal joint wide. Length, 15: rostrum, 4; 
width, 7 mm. 
Hah. — Tasmania (type in Mr. A. Simson's collection). 
A very distinct species, belonging to the sucrisus groap. 
Each elytron has the third interstice subtuberculate at base, 
and with two moderately distinct tubercles between the base 
and the large tubercle, this is obsoletely granulate and out- 
wardly directed. 
POROPTERUS RHYTICEPHALUS, n. Sp- 
Rather sparsely clothed with small scales, each puncture 
containing a distinct scale ; tubercles feebly setose. 
Strongly convex, subcylindrical. Head and rostrum 
roughly punctate ; eyes finely faceted : ocular fovea rather 
large. Antennae black : funicle longer than scape, its second 
joint longer than first. J'rottiorax moderately transverse, 
sides rounded ; constriction irregularly continuous across sum- 
mit ; with numerous granules ; across middle a series of four 
large rounded punctate granules : with a distinct media.n 
carina, which terminates before base and apex. Srutrllmn 
subtriangular. Elytra oblong-ovate, not much wider than 
prothorax, and more than twice as long ; with moderately 
large, round punctures, and with numerous subtubercular 
elevations ; second interstice with two tubercles of moderate 
size : one near base round and slightly larger than those on 
prothorax, the other just beyond middle, suboblong, and smal- 
ler ; each side near summit of posterior declivity with a large, 
obtusely conical tubercle; apex without tubercles- Abdomen 
with third and fourth segments depressed below second and 
just perceptibly below fifth. J.eys moderately long and thin : 
posterior femora just passing elytra. Length, 9^ ; rostrum, 
21 ; width, 4 mm.
