1456 FURTHER NOTES ON AUSTRALIAN COLEOPTERA, 
the form of a vitta. The anterior femora are scarcely distinctly 
dentate beneath. The pubescence on the specimen before me, which 
is probably a female, is very pale bro’wn rather than white, but 
the specimen is not fresh.

LONGICORXES. 
Pachydissus (Ploc.ederus) AUSTRALASI.E, Hope. 
The collection made by Mr. J. P. Tepper, near Port I)arwin» 
includes a specimen (^) of a Cerarnhyoid which seems to agree 
very well with Mr. Hope’s description of this insect, except that 
it is considerably larger (14|^ lines) than the size there mentioned. 
Considering the tendency of the Cerambycidce to vary in size, I 
think a difference of four lines in length not incompatible with 
identity. The resemblance of this specimen to P. sericus, Xewm., 
is exce.ssively close, except in respect of the antennfe, which are 
very different, being nearly twice the length of the body, and 
ha\'ing their joints differently proportioned ; the 3rd joint is 
nearly half again as long as the 1st, the 4th equal to the 1st, the 
3rd and 4th strongly (but not so strongly as in P. sericus) swollen 
towards the apex, the 5th .same length as 3rd, the 6th and remain- 
ing joints each longer and more slender than the joint next 
before it.

The size of this species is given by its author as “ 10 lines.” I 
have a single specimen of that size but the average size is 8 
lines. 
Tryphocharia. 
The genus Tryphocharia bears a conside ruble re.semblance to 
Phoracantha, from which Mr. Pascoe, its author, distinguishes it 
by the small size of its prothorax in proportion to the elytra, by 
its more linear femora, its forehead more narrowed in front, its
