146 Notes on Australian Coleoptera. 
same family, change Coptva and Loricera. In every family 
there are, in his book, names of the different genders, and so 
in the Scaritide he has Pasimachus, Carenum, and Clivina. 
The character which separates Hudema from Panageus 
is to have the anterior tarsi of the male simple and similar 
to those of the female; all the Australian sorts known to 
me belong to Hudema. 
These insects are (with the exception of Convexa and 
Azurea) so much like one another that I shall only attempt 
to give the differences which exist between them. 
1. Hudema Convexa, of Macleay, junr., which I have 
recelved from Port Denison, is a most distinct insect, having 
entirely the appearance of the large, broad Indian sorts, its 
length is over 9’. 
2. Kudema Australis, of Fabricius: this is the most com- 
mon Australion sort; its size is about 53’; itis easily dis- 
tinguished by the orange coloured spots of the elytra, which 
are proportionately small, and of which the humeral are 
almost round. 
I have it from the south of Queensland, the Clarence Riven 
Sydney, &e. 
3. Hudema Australasice, of Chaudoir,is of about the same 
size as the preceding, but the spots are of a dark red and 
much larger, the humeral more or less square. 
From Sydney, Melbourne, the Darling River, and South 
Australia. 
4. Hudema Alternams: this is a new sort, being about 
7 lines long; it is very much like Australis, but much 
larger, and more elongated ; it has the centre of its head per- 
fectly smooth ; the thorax is of a pentagonical form ; the 
costes of the elytra are alternately much larger than the 
intermediate. 
From Rockhampton. 
5. Hudema Rockhamptonensis: also a new sort; its length 
is 7’ ; 1t comes very near the preceding, but is smaller 
and broader; the head strongly impressed, but almost 
without punctures ; thorax broader than in Aliernans, and 
the sides more rounded, with the lateral border narrower ; 
elytra shorter, with the costze equal. 
Also from Rockhampton. : 
Note.—In the two last sorts the spots of the okie are 
rounded and of an orange colour. 
6. Hudema Elongata: : length 74’; more elongated than 
the other species ; head covered with very strong punctures ;
