36 Notes on Australian Coleoptera. 
longitudinal carina on the middle. The abdominal seg- 
ments are soft ; the eighth is gibbous, and surmounted by 
two crooked appendices ; the legs are rather short. This 
larva is entirely yellow, with the head and prothorax of 
a dark green; the mandibulee of an obscure brown. It is 
easy to see how very much this larva resembles those of the - 
two European sorts that have been described. 
The second larva I have to mention belongs, as I already 
stated, to C_ Parryt ; it is of a very different form from the 
other, the head and prothorax being of a most extraordinary 
size ; at least four times as broad as the body, and nearly as 
long. ‘The first is broad, transversal, with two eyes nearly 
equal on each side; the labrum is rounded in front; the 
mandibulee shorter than in the preceding sort ; the antennze 
of the same form; the prothorax is semicircular, with its 
anterior angles prolongated ; the. anterior margin is also 
advanced in its middle; the two other thoracic segments 
and those belonging to the abdomen are narrow, soft, and 
hirsute; theeighth isslightly gibbous, but withoutappendiees ; 
the legs are robust and proportionately pretty long. The 
insect is of a dark yellow ; the head of a metallic green, as 
is also the prothorax ; but the last is covered with a short 
white and snowy pubescence. 
In a following paper I will describe a large number of 
new sorts of Australian insects, belonging to the family of 
Carabide. I feel it my duty to express here my thanks to 
all those who during my three years residence in this 
colony, have so liberally granted me their co-operation in 
the formation of my very considerable collection of Aus- — 
tralian beetles, and in particular to our great botanist, Dr. 
Mueller, who most liberally has put me in correspondence 
with the greatest part of those who devote themselves to 
the study of the zoology of the Southern Hemisphere. 
Since the above was written, my knowledge of Australian 
Cicindelide has received the following additions :— 
Two new sorts of tetracha have been sent me by the 
Rev. Mr. Bostock, of Western Australia. They both came 
from Nickol Bay. 
Tetracha Bostockiz: length, 6°, breadth, 2’3 of a fine 
metallic green ; elytra black, with a yellow margin which 
projects, towards a third of its length, a strong and oblique 
ramification extending towards the suture. The surface of
