Notes on Australian Coleoptera. 139 
Eutoma ; it has the long cylindrical form of the latter, but is 
very distinct from both by the form of the palpi. 
Neocarenum Singularis : length 13’; of a dull black ; 
longitudinal grooves of the head. sinuous and diverging in 
front towards the anterior angles of the head; thorax 
long, with the sides parallel, rounded behind, rather 
sinuous in front, it is bordered, has a _ longitudinal 
sulcate in the middle; there is a faint depression at the 
anterior angles, and a strong one at the posterior ; elytra of 
a very long oval form, almost parallel, tolerably narrower in 
front than at their posterior part; the humeral angles are 
well margined and pointed; a line of widely parted points 
follows the internal side of the margin, and a series of very 
large punctiform impressions extends laterally in a longitudi- 
nal line at some distance from this margin; the anterior 
tibiz are bidentated. 
Swan River. 
Neocarenum Kreusleri: length 134° ; very much like 
Singularis, but of a brilliant black ; thorax rather broader 
in front than behind ; elytra having the same markings, and 
in addition a strong punctiform impression behind, towards 
the middle of the breadth ; teeth of the anterior tibie very 
long and acute. 
From Gawler, South Australia. I dedicate it to Mrs. 
Kreusler, a German lady, who devotes her time and great 
abilities to the study of the Entomological Fauna of her 
adopted country. 
EUTOMA. 
This genus of Newmann has not generally been ad- 
mitted, but it appears to be very distinct from Carenum by 
its long linear general form, its palpi very securiform, its 
antenne increasing in thickness from the base to the end ; 
the thorax is always longer than broad ; the anterior thighs 
dilated and like emarginated below. Carenum Violarewm of 
MacLeay (“'Trans. Ent. Soc. of N.S.W.”) must also be placed 
here, as probably also Megacephalum of Westwood. 
Before entering into the description of the new sorts of 
this genus contained in my collection, it is necessary to be 
certain of the sort (Tinctillatwm) on which Newmann has 
established his genus Hutoma. This I find very difficult to 
ascertain in insects so nearly allied as are the different 
species. His insect is said to be black, with the sides of the 
elytra blue. ‘This only applies to a specimen I received from
