gradually rounded : elytra more elongate, less convex, 
less robust, the rows of punctures larger, more distinct, 
the punctuation on the intervals less confused, than in the 
preceding : legs and antennas ferruginous ; 3rd joint of the 
latter much longer than the 4th ; the 11th subglobose.

Hah. — Champion Bay. Two examples by M. Duboulay, 
By its more elongate, more parallel and less convex 
form, and somewhat differently formed prothorax, I have 
no doubt as to this being specifically distinct from all the 
preceding. 
ADELIIDES. 
Adelium {Seirotrana^ strigipenne, n. sp. 
Oblong-oval, flattish above, black, shining; sparsely 
and indistinctly — save on the head — pubescent: head 
coarsely and reticulately rugose-pimctate, the punctures 
oblong, front not excavated ; 3rd joint of antennre a little 
shorter than 3 — 4 united ; antennary orbits rounded (not 
angulate) at the sides ; prothorax transverse, the anterior 
angles less acute than in catenulatum, and directed towards 
the lateral margins of the head; the sides much less 
strongly incurved behind the middle — the base is conse- 
quently considerably wider than the apex, the margins 
toothed only from the middle to the base, the punctuation 
is more confluent, the punctures often very elongate ; 
median dorsal furrow faintly marked, the fovea at each 
side the disk much fainter, the median basal one obsolete : 
scutellum smooth : elytra subparallel to two-thirds their 
length, shoulders narrowly rounded; each elytron with 
10 narrow, feebly elevated, slightly waved (both laterally 
and vertically) costfe, which are crenately punctured at 
each side, and often also (especially the sutural) at top ; the 
intervals are very feebly bicostate, or trisulcate, the inner 
sulcus the most marked, and frequently interrupted by the 
confluence of the two secondary (or intermediate) costge, 
which are also waved like the primary costte ; when viewed 
from above the elytra appear to be irregularly transversely 
tuberculate ; when viewed from the side they have a finely 
rippled appearance : underside, legs, and antennae, black.

Hah. — " Australia." One example. 
Very distinct from all the described species of this 
section of the genus by the peculiar sculpture of the elytra, 
which almost defies description.
