long, slender, with the first article much longer than the 
Others, the second the shortest of all, the third rather 
longer than the following, which are hirsute. Legs rather 
slender; anterior thighs rather inflated, and canaliculated on 
their inner side; tibias of the same pair strongly emar- 
ginated; spurs situated one before the end and the other 
apical. ‘Tarsi slender, the anterior ones rather dilated in the 
male, spongious beneath; the first article the longest, the 
other three cordiform, the fourth being the shortest; claws 
simple. Head small, oval, narrowed behind the eyes, these 
small; thorax something like the one of Cychrus rostratus ; 
elytra oval, rather long, separated from the thorax. ‘This 
genus is dedicated to the illustrious author of the “ Genera 
des Coléoptéres.” 
Lacordairia Cychroides: length 5’; of a brownish black ; 
head oval; thorax almost square, rather narrowed behind, 
with two strong longitudinal impressions on the posterior part, 
a sulcate in the middle, and the sides strongly marginated ; 
its anterior and posterior angles rounded; elytra rather 
long, covered with fine regular and deep longitudinal strize ; 
the parts of the mouth, and intervals of the two strize 
impressed towards the end; antennee, from their fourth article, 
and tarsi of a light brown. 
Clarence River and Brisbane, under stones. 
Lacordairia Proavma: length 5’; differs from Cychroides 
by its form, broader and shorter; the thorax is wider and 
about as broad as long, with its anterior angles more 
advanced; the elytra are also broader, more of an oval form, 
with the strize generally deeper. 
From the mountains of Victoria \ Yankee Jim). 
Lacordaiwria margimata: length 3}; very nearly allied 
to Calathoides, and of the same form; the impressions of the 
posterior part of the thorax shorter; strize of the elytra not 
deeper towards the sutura than near the margin; a yellow 
margin to the elytra. 
I found a single specimen of this insect at Melbourne in a 
flood of the Yarra River. It probably inhabits the moun- 
tains of Victoria. _ 
Lacordairia angustata : length 6’; very much of the same 
form as Cychroides, but more elongated; thorax longer, a 
little more cordiform, with the posterior angles more erect ; 
elytra a great deal longer, being at least two and a half 
times the length of the thorax, for all it is larger itself than 
in all the other sorts. |
