good deal clothed with rather long pale brown woolly pubescence, 
the elytra being thinly sprinkled with pale hairs. The prothorax 
is the same width (from the base of one spine to that of the other) 
as it is long down the middle, with its upper surface a good deal 
flattened, and its sculpture of the character usual in the genus, its 
lateral spines long, slender and curved towards the elytra. The 
antennae reach a Little beyond the elytra ; their joints from the 
4th inclusive extremely flattened (but not carinate on the upper 
face), joints 3-8 bearing two equal spines (one on each side) at the 
apex, — all the spines directed, hindward rather than outward, and 
all small, the pseudo-twelfth joint short but rather well defined ; 
the elytra are truncated (rather obliquely) at the apex, each end 
of the truncation bearing a long sharp spine. The hind tibiae are 
a little curved. 
T. Odewahni, Pasc. 
In his description of this species its author states that its elytra 
have the apex “ rounded,” but in a figure (given by him sub. 
sequently in the Journal of Ent., Yol. II.) the apices of the elytra 
are represented as straightly truncate. I have never seen a 
Tryphocharia having rounded elytral apices, but the species that 
is most plentiful in South Australia (I have specimens from the 
far west, from Adelaide, and from the Victorian border) has the 
apices almost straigbtly truncate with the inner end of the 
truncation produced in a short sharp spine. The elytra also have 
an obscure rather large blackish spot on the disc a little in front 
of the middle, which is represented in the figure of T. Odeicahni 
but not mentioned in the description, and which appears to be 
highly characteristic of the species. In other respects this insect 
agrees with both description and figure of T. Odexvahni and, I 
have no doubt, is that species. It differs from T. hamata 
structurally in having the lateral spine of the prothorax smaller 
and straight (or nearly so), and the external end of the truncate 
apex of the elytra not spined. The surface of the prothorax is 
much flattened. The antennte scarcely difl'er from those of 
T. 4ama<a except in being a little shorter, with the pseudo-twelfth
