mary of matters that I have already discussed at some length 
in a former memoir (Tr.R.S.S.A., 1898, p. 18, etc.), to whirli 
I would refer the reader. 1 repeat the outline merely to 
avoid the need of having another memoir in hand while mak- 
ing use of the present one. Referring to the tabulation (m 
which I have departed somewhat from the characters relied 
on by Lacordaire) I may remind those who mav nf:e it that 
in characterising large aggregates of species it is almost in- 
variably impossible to find single sharply defined points of 
difference (such as are required for a rabular state- 
ment) that can be relied upon as strongly de- 
veloped in every member of the aggregates m 
question. The truth of this remark is illustrated ry 
the character assigned to the Systellojndes, inasmuch as there 
are genera of the Sericides in which to a casual glance it cer- 
tainly seems to be present. I have discussed this point before 
(loc. cif.J, and therefore merely mention it now with the added 
remarks that, apart from this character, I cannot see how the 
Systellopides are to be distinguished from x>he Sericides as at 
present constituted, and that I am unable to satisfy myself 
that the apparent labrum is really that organ in the Systello- 
pidesi, and is not in such Sericides as Phyllotociis. 
SYSTELLOPIDES (Firefc subtribe of Australian MelolonthidesJ. 
This subtribe consists of eight species, described by Dr. 
Sharp, to which it seems probable that the two species of the 
genus Prochelyna ought to be added, and I have two new 
species now to be described. If Frochelyna is distinct from 
all Dr. Sharp's genera, these twelve species must stand divided 
into eight genera. They are all extremely rare in collections. 
Dr. Sharp has conjectured that Metascelis fierrilis, Westw., the 
habitat of which is not known, may be a, Systellopid, in which 
case it might probably be Australian. Dr. Sharp's memoir 
on the subtribe (Ann. Mus. Gen., ix., pp. 311, etc.), sup- 
plies an excellent tabular statement of distinctive characters 
of those species that can be confidently referred to it. I have 
no information as to the habits of these insects.
