Notes on Australian Coleoptera. 119 
Note.—These three sorts are nearly allied to Bimaculatus, 
of McLeay, jun. (“ Trans. Ent. Society of New South Wales,” 
Part II.), from Port Denison, but are very distinct by their 
much smaller size, more elongate form, the disposition of 
the coloured band of the elytra, &c. 
Adelotopus Brunneus: length 23’; entirely of a rather 
dark brown, rather opaque; body not very elongate, but 
with its sides parallel; head in great part enclosed in the 
thorax; this latter broader behind than in front, its sides 
equally marginated aud rounded, a very faint transversal 
impression near its posterior margin; elytra darker at that 
end, marginated laterally, with a very faint, longitudinal, 
‘depressed line near the sutura; inferior part of the body and 
legs brown, but rather lighter than the upper surface. 
Swan River. 
Adelotopus Castaneus: length 24’; more elongate and 
cylindrical than the preceding; of a lighter and more bril- 
liant brown; head more free from the thorax, with its sides 
mareinated but straight and oblique; a transverse impression 
backwards; elytra entirely of the same colour, with Mae 
faint longitudinal striz, when seen through the lens. 
Swan River. 
Note—Brunneus and Castaneus are nearly allied to 
Aphodioides, but easily distinguished by their smaller 
size, &c.; this latter I have from South Australia, Victoria, 
New South Wales, the Paroo River, and Port Denison; some 
of the latter specimens are narrower than the others; this 
may be a sexual character. 
Adelotopus Filiformis: length 22’; long, filiform, cylin- 
dric ; of a shiny brownish black, with the posterior third of the 
elytra red; head rather small for the genus ; thorax longer 
than broad, marginated and straight on its lateral sides; 
bi-impressed backwards ; elytra smooth, with a faint longitu- 
dinal depressed line near the sutura; inferior parts of the 
body, mouth, and legs of a brilliant brown; abdomen and 
tarsi red. 
Adelaide. 
Variety.—The red colour covering more than the poste- 
rior half of the elytra. 
Melbourne. 
All the sorts we have seen are brilliant and shiny, the 
following are more or less rugose; in this division comes 
Cylindricus (Chaudoir), which is not from Melbourne, as 
stated by that author, but from Adelaide.
