Altlioiig-b closely allied to Fl. aplusirifer Westw. (Linu. Trans, svi. p. 664, pi. XXXI I I , fig. 51; Arcana
Ent. pi. LXXXVI I I , fig-. 3), the present insect has the body and antenna less depressed; the head has an oval
depression between the front of the eyes; the shape of the clava of the antemiie diflcrs somewhat from that of
PI. ajdustrifer, as can be best seen by comparing- the coloured figure with the outline of the clava of FL aplust
rifer (fig, 4 b). The middle femora have a remarkable character on their inner surface, consisting of a group of
about twelve small raised ridges arranged in a radiating manner (tig. 4 a).

PLATE XAT:II, FIGS. 2 and 3.
The outlines here given represent the basal joint (fig. 2 a), and the clava of the autennte (2 h), of this species,
and the prothorax, seen from above (2 c). In the second of these figures the margin is slightly trisinuated
near its outer extremity, the lobes of the sinuated portion being clothed with short hairs; the basal joint of the
antenna? is rather wide at its extremity, and the prothorax has the dilated portion of its lateral margins slightly
angulated, and the narrowed basal portion distinct. Certain individuals, however, have the clava of the antenna;
entire along the outer margin, the whole margin being slightly setose (fig. 3 a ) ; the basal joint of the antenna
is narrower, and consequently more acute at the tip, and the prothorax has the lateral margins less angulated,
and the basal portion not distinct (fig. 3 h); the middle and hind tibia; have the outer apical angle acute, and
extended backwards. In all other respects the specimens appear identical with the ordinary type of the species.
I t is possible these may be sexual distinctions; if not, they must be regarded as specific distinctions (although of
a light character), and the name oi Flatp-kopaltis Ficietii may be assigned to these individuals.

represented in fig. 7.

The antennse are about the size of, or slightly larger than, the prothorax. The length of the elytra=2i
the length of the prothorax. There is a very slight impression on each side of the crown of the head, close to
the narrowed neck. The tibia; are compressed, flattened, rather thickened at the tip.
