shorter antennae, and especially by the spinose joints of the latter 
bearing tioo spines instead of one only. It may be added that the 
antennae have a more or less distinct indication of a twelfth joint. 
The genus Xypeta (formed by Mr. Pascoe at the same time as 
Tryphocharia, for an insect previously described by him as 
Phoracantha 'grallaria) appears to differ from Tryphocharia only 
by its forehead wider in fi’ont, its longer antennae, and its shorter 
anterior and longer posterior legs. There can be little doubt, I 
should say, that Phoracantha gigas, Hope, should be placed in 
this genus, for though Mr. Hope’s description gives very little 
information about the structural characters, the accompanying 
figure represents it as having long antennae with two spines on 
each spinous joint, and posterior femora slender and much longer 
than those of Tryphocharia. 
It is very Likely that among the species described as Phora- 
cantha there may be others attributable to Tryphocharia., and 
possibly to Xypeta. The description of P. acanthocera, Hope, 
reads much like that of a Tryphocharia, but as it contains no 
mention of the length of the antennae, nor of the number of 
spines on their spinose joints, nor any statement of the size of the 
insect, no positive conclusion is possible without a re-examination 
of the type. It is much to be wished that those who possess any 
of the original types of the Australian species insufficiently 
described V>y the earlier author’s would publish a full and minute 
description of the same in the Transactions of some Australian 
Society. 
The following species attributed to the genus Trypitocharia I 
liave not seen, and am satisfied are quite distinct from anything 
known to me, viz., T. ifitchelli, Hope ; T. superans, Pasc. ; and 
T. Mastersi, Pasc. The first of these is said to be found in 
N.S. Wales and Queensland ; from the description and figure it 
would appear to be characterizeil e.specially by the very small 
spine on either side of the prothora.x, the elytra distinctly 
bispicose at the apex, and the markings of the latter, which are 
of a pale yellow colour, with the base, the suture, the lateral
