120 Notes on Australian Coleoptera. 
Adelotopus Obscwrus: length 22°; brown, obscure, en- 
tirely covered with rugosities ; very much like [psoides, but 
shorter, the rugosities much stronger and extending over the _ 
axillary angle and the basis of the elytra; the longitudinal 
strize of the latter much less marked; the under side 
of the body, mouth, antennee and legs of a brilliant reddish 
brown. 
Sydney. 
Variety ; elytra of a light brown with a dark-coloured 
marein. 
Sydney. 
A delotopus Bicolor: length 24” ; entirely covered with a 
fine granulation ; body moderately elongate, rather broad, 
with its sides parallel] ; thorax broad and transversal, with a 
rather wide lateral margin obliquely truncated at its 
anterior angles; a very slight transversal depression near 
its posterior margin ; elytra covered with punctures, rather 
glossy and showing very faint longitudinal striz ; their 
colour is of a ight yellowish brown, with their posterior part 
and their lateral margin almost black; mouth and inferior 
parts of the body of a ight yellowish brown. 
From the Loddon River, Victoria. 
Ozende. 
This family is almost wanting in Australia, being only 
represented by Mystropomus, of which one single species 
has been described. A second one figures in my collection. — 
Mystropomus Chaudoiri: length 5’; the form is like 
Subcostatus, but much smaller; the thorax is narrower in 
its posterior part; the elytra shorter, with a faint longitu- 
dinal costa between the four larger ones; this insect is 
black, with the lower side of the body, the parts of the 
mouth, antenne, and legs, of a dark reddish brown. 
From the Clarence River. 
Ditonde. 
The only Australian representative of this group, so. 
numerous in Europe, belongs to the little genus Apotomus, 
which had been considered as entirely confined to the Euro- 
pean and African shores of the Mediterranean, but I have 
found a sort at Bangkok (Siam), and another from Madras 
is in my collection. 
Mr. McLeay, jun., mentions that a sort of Apotomus has 
been found at Picton, but he has not described it, and so I 
cannot say if it is the same as the following—
