thirds of the length; a series of punctiform impressions 
extend near the margin; Jower side of the body and legs 
black ; tarsi brown ; antenne covered after the first article

Mountains of the south of Queensland. 
Leiradiva Auricollis: length 52’; black; thorax of a 
fine gold colour ; elytra purple ; thorax more rounded at its 
anterior part than in the preceding species; elytra more 
oval ; similar in other respects. 
Clarence River, New South Wales, and Rockhampton, 
Queensland. 
Cnemacanthide. 
This family is very extensively represented in Australia, 
and on this continent the most southern parts seem almost 
to have its monoply. They can in general be called antartic 
insects, the greatest number being confined to the extreme 
south of America, such as Chili, and the Straits of Magellan ; 
and in Australia, to Victoria, South Australia, Van Dieman’s 
Land, and particularly New Zealand. Few extend to the 
north of South Wales, and to the southern parts of Western 
Australia. Those that are found in other regions of the 
world are in general confined to great altitudes. 
The genus Oopterus of Mr. Guerin, which Mr. Lacordaire 
places in this group, belongs manifestly to the Subulipalpi, 
among which the author of this generic division had most 
properly classified it. 
MECODEMA., 
This genus of Mr. Blanchard has been very little known 
till the present; it is founded on a large insect, Sculptura- 
tum, which is not rare in the mountains of New Zealand, 
near Dunedin. <A considerable number of other sorts have 
been found since, but have not yet been described. 
Broscus Gineus of White, belongs also to this genus, as 
also very probably the Promecoderus Lottinii, Brulle, 
“ Hist. Nat. des Insectes,” vol. iv. p. 459. As yet no Promeco- 
derus has been found in New Zealand, and if one could 
admit that there has been an error in the locality, that 
insect might be Promecoderus Concolor. 
Mecodema Howittti: length 13’-16’; this is the largest 
species known yet ; its colour is of a dark copper ; the fore- 
head is almost smooth, but strong transverse striole cover 
the anterior parts of the head ; the thorax is broad and cor-
