Many specimens, found by Mr. Walker on sandy sea- 
shores, at roots of bent grass. This species is said to 
be widely distributed in South Australia.

Hab. Tasmania—Hobart and Launceston. 
I have examined the type of Asida serricollis, Hope, 
from Adelaide; it does not differ from the Tasmanian 
insect. ‘The lateral thoracic teeth are almost or quite 
obsolete in some specimens. Under stones and logs 
in dry places, common (Walker). 
OPATRUM. 
Opatrum, Fabricius, Syst. Ent., p. 76 (1775) (part.). 
This genus is apparently well-represented in the 
northern parts of Australia, whence very few species, 
however, have been described as yet. Of the five species 
received from Mr. Walker from that continent, four are 
apparently new. Opatrwm seems to be replaced in 
Tasmania by the genus Cestrinus. It may be noted here 
that the descriptions of Opatrum seriatum and O. aus- 
trale, Boisd., are perfectly unintelligible.
