impressions on the interval between the second and third 
strie, a little after the middle of the length, the margin 
impressed ; tarsi and antenne brown. 
Clarence River. 
ECCOPTOGENIUS. 
This genus of Baron Chaudoir being very little known, I 
give here the generic characters of the Australian species. 
Mentum broad, transverse, emarginated ; the excavated part 
having no tooth, but being convexly rounded ; the wings 
broad, rounded externally, obliquely truncated internally. 
Labrum transverse, very strongly emarginated in form of a 
half-moon ; palpi long, the maxillary with their first article 
short, the second long, arched, rather broad, and depressed ; 
the third shorter, but still rather long and convex ; the last 
rather longer than the former, oblong, elongated, truncated at 
the apex ; the labial have their first article small, the two 
following long, the last oblong, truncated at the apex. An- 
tennze moderately long, the first article strong, the second 
rather shorter than the others, which are about equal. Man- 
dibule strong, very slightly arched, carinated, maxille 
slender, arched, ciliated inside; tarsi having their first 
article longer than the others; in the male the three first 
articles of the anterior tarsi are dilated, and have squamule. 
The insect I refer to this genus, has entirely the form of 
a small Feronia of the Pterostichus group, but it is distinct 
by its marginated labrum. ) 
Mr. Lacordaire describes the labrum of Eccoptogenius 
as being angularly emarginated, but this is not the case 
in five or six Indian species which are in my collection. 
Liccoptogenus Feronoides: length 32’ ; of a dark bronzed 
colour, almost black ; head rather small, oval, impressed in 
front; thorax lightly cordiform, rather narrower behind than 
on the anterior part; anterior angles rounded, posterior 
ones almost straight; the impressions well marked, and a light 
centre impression on the posterior angles ; elytra broader 
than the thorax, oval, strongly striated; a short, abbreviated 
stria near the scutellum, after the sutural one; the margin 
impressed ; legs of a dark brown, almost black; antennz 
and palpi of a light red brown. 
Deep Creek. 
Note.—This is entirely an Indian form ; the genus was 
formed on a species from the north of India, but I have 
taken several others in Siam.
