160 Notes on Australian Coleoptera. 
diform, it is rather smooth, with some transverse irregular 
striole ; on its anterior margin, the striole are longitudinal, 
the margins are entire ; elytra oval, rather long, covered with 
longitudinal lines, rather elevated, and with their intervals 
most irregularly, but strongly, punctated and granulated. 
This fine insect has been found near Christchurch, in New 
Zealand ; I owe my specimen to the kindness of Dr. Howitt. 
Note.—The same as in all the other sorts the thorax has 
a longitudinal sulcate in the middle, and two transverse im- 
pressions, one in front and the other behind, with others at 
each angle ; it is useless to repeat this for each species. 
Mecodema Rectolineatum: length 13’; nearly allied to 
Sculputatum, but the thorax more smooth, and the elevated 
lines of the elytra regular, with the bottom of the striz 
strongly punctated ; they are deprived of those irrecular 
depressions so remarkable on the typical species ; the general 
form of the elytra is also shorter. 
From the mountains near Dunedin, New Zealand. 
Mecodema Lucidum: length 12’; of a rather dull black, 
smooth ; head with a transverse line of very small points on 
the forehead; thorax having vestiges of faint transverse 
striole only on the middle longitudinal sulcate ; elytra with 
punctated striz, almost obliterated near the sutura, but very 
strong on the sides and behind; they have also a sort of 
longitudinal and smooth costa near the lateral margin, which 
is bordered externally by a few large irregular punctures. 
New Zealand. ' 
Mecodema Crenicolle: length 13%; of a dark copper 
colour ; head covered with irregular rugosities ; thorax with 
its sides crenulated, and its surface covered with transverse 
striole; elytra oval, long; covered with very strong and 
large points dispersed in irregular longitudinal lines; they 
are much deeper and confluent on the sides; base of an- 
tennee and legs rather reddish. 
This fine insect comes from Auckland (New Zealand). 
Mecodema Simplex: length 13’; of a rather shiny black, 
having a metallic tinge; head and thorax covered with 
transverse undulating striole; others longitudinal on the 
internal side of the eyes; elytra regularly striated ; the 
strie with very small punctures near the sutura, but those 
near to the margin formed of large square points ; the inter- 
vals of the striz are nearly carinated ; antennz and legs of 
a dark brown. 
Auckland, New Zealand.
