Rostrum stout, curved, strongly carinate along middle, 
the carina sometimes concealed. Scape straight, not very 
Stout; two basal joints of funicle subequal.  Prothoraz di- 
lated in middle, apex slightly narrower than base, median 
line feeble; with small regular obtuse tubercles, neither tu- 
bercles nor median line showing through clothing. Scu- 
tellum small and indistinct. Ælytra in male narrower. than 
prothorax at base, and wider beyond: middle; in female as 
wide at base and slightly increasing to beyond middle; seri- 
ate-punctate, punctures moderately large, round, and regu- 
lar, the interspaces densely punctate, finer punctures entirely 
concealed; suture, second, fourth, and sixth interstices 
slightly raised. 7104: moderately strongly curved, and all 
(the intermediate less noticeably than the others) dilated at 
apex. Length, 6; width, 21; variation in length, 5-7 mm. 
Hab.—N.S.W.: Clarence River, Windsor, Sydney. 
The basal segment of the abdomen in the male is strongly 
depressed, and clothed with long setze between the coxæ, in 
the female it is but feebly depressed and the clothing is nor- 
mal; the sutural interstice is slightly contracted near the 
base, but dilates beyond the middle, so that the rows of 
punctures appear to be somewhat curved. Numerous speci- 
mens of both this and the preceding specimens were obtained 
during a flood. Although the sculpture of abraded speci- 
mens is seen to be very different, perfect specimens are not 
very dissimilar, but they are readily distinguished by the 
clothing and shape of the tibiæ. 
MANDALOTUS SCABER, n. sp. 
Male. Black; antenne and legs dull red, tarsi pale red. 
Clothing as in the preceding species, except that the tibiæ 
are not clothed beneath with long hair. 
Rostrum stout, curved, carinate. Scape thinner than in 
the preceding species and slightly curved, two basal joints 
of funicle subequal. Prothoraa strongly transverse, apex 
distinetly narrower than base; median lime distinct, with 
numerous obtuse tubercles, and which are traceable through 
clothing. Scutellum small and very indistinct. Elytra 
ovate, small, considerably narrower than prothorax at base, 
and nowhere as wide as prothorax at its widest; base semi- 
circularly emarginate; seriate-punctate, the punctures mode- 
rately large; each with a few obtuse tubercles, of which the 
most distinct are on the second and sixth interstices at base 
and one behind each shoulder. Basal segment of abdomen 
widely depressed, the depression continued from  metaster- 
num. All the fibie strongly curved and dilated at apex, 
the posterior suddenly narrowed close to apex. Length, 5; 
width, 2 mm.
