Notes on Australian Coleoptera. 161 
Mecodema Blagravia: length 10’; of a shiny brownish 
black ; head smooth, with two longitudinal striz behind 
each eye, and a transverse impression in front of them ; 
thorax cordiform, rather depressed, rounded and marginated 
laterally, with a slight transverse impression on the anterior 
angles-and a large and rounded one near the posterior ones ; 
its surface presents transverse striole; elytra oval, rather 
strongly striated ; a few very strong punctiform impressions 
on the posterior part of the margin; lower side of the body 
black; legs and parts of the mouth red; basal articles 
of the antenne brown, the others black, and after the third 
hirsute. 
Mountains of Victoria, found by the lamented Mr. Louis 
Blagrave. 
Mecodema Impressum : length 103’; of a dark copper 
colour, rather brilliant ; head smooth in front, and punctured 
on its posterior part; thorax rather smooth, with faint 
transverse striolz ; the anterior angles covered with a dense 
puncturation ; elytra rather long, covered with strize, which are 
very finely punctured, and with the intervals between them 
smooth towards the sutura, aud formed of very strong punctures 
near the margin; on the interval between the seventh and 
eighth striz are three or four rather large but irregular punc- 
tiform impressions; a sort of smooth longitudinal carina 
follows near the external margin, and is bordered externally 
by a line of large and distinct punctiform impressions ; the 
posterior part of the elytra is covered with very strong and 
irregular impressions ; legs and antennee black. | 
Mountains near Dunedin, New Zealand. 
Mecodema Alternans: length 11%’; this insect is very 
nearly allied to the preceding, and has the same punctiform 
impressions of the elytra, but they are very different, being 
disposed so as to leave alternatively broad and narrow 
spaces between them ; the broad spaces number four, having 
two puncturated striz between each; the colour is rather 
darker than in Impressum, and the elytra rather broader 
and of a more oval form. | 
This insect was brought from the neighbourhood of Otago, 
New Zealand, and is in Dr. Howitt’s collection. 
Note.—The above species have all the same fascies, being 
rather depressed, with the thorax more or less cordiform. 
The following have a different appearance, but the parts of 
the mouth, of which I have made a minute study, being 
similar, [ have to include them in the same genus. The in-
