In appearance this species strongly resembles hduherru- 
lafns, and it is remarkable that the two should have exactly 
similar tubercles at the base of the elytra ; the facets of the 
eye, however, are very much finer (less than half the size) 
than in that species, and forbid its being regarded as a variety. 
Many of the prothoracic and abdominal scales appear to be 
conical in shape. 
POROPTERUS RUBUS, PasC. 
Two specimens, from Cairns, apjDear to represent a 
variety of this species. They differ from typical specimens m 
having the clothing longer and denser, the apex of the elytra 
very obtusely mucronate, and all the tubercles more obtuse ; 
of the sutural tubercles the second is almost obsolete, being 
transformed into a feeble ridge. 
Decilaus apicatus, n. sp. 
Densely clothed with large soft scales, varying from a 
dingy white to sooty brown, and causing the upper surface to 
appear speckled. Under surface with longer dingy-whitish 
scales ; pectoral canal densely squamose. 
Head indistinctly but evidently coarsely punctate. Ros- 
trum stout; coarsely punctate, punctures irregular in front of 
antennae, behind them evidently in seven rows, the lateral 
row very distinct. ScajDe stout, almost the length of funicle, 
inserted close to apex, Proi liorax (by measurement) sllgntly 
longer than wide, with moderately large, round, shallow punc- 
tures, which are entirely concealed. FAytra oblong-cordate, 
scarcely twice the length of protnorax, striate-punctate, both 
striae and punctures entirely concealed, punctures moderately 
large, but not as wide as interstices, these flat and punctate. 
A hclomen with the punctures almost entirely concealed. An- 
terior tihicE at apex with a glabrous, outwardly rounded, and 
obliquely flattened plate, from which the terminal hook pro- 
ceeds. Length, 5 ; rostrum, 1^ ; width, 2^, mm.

burn, No. 1492). 
The anterior tibiae are very peculiar. The margins of 
the elytra in the vicinity of the abdomen are perfectly gla- 
brous in the (two) specimens under examination, this char- 
acter being invisible from above ; it does not appear to be due 
to abrasion. Each puncture of the rostrum behind the 
antennae contains a large scale, which entirely conceals it. but 
as the scales can be traced in seven rows the punctures are 
probably also in rows. 
Decilaus squamipennis, n. sp. 
Prothorax with three feeble whitish lines, each puncture 
containing a scale, the majority of which are dingy brov.-u, and
