378 RHYNCHOPHORA, [ Phytobius. 
Marshy places ; on aquatic plants, especially Polygonum amphibiwm ; also in moss 
and at roots of grass; very local and rare; Lee, Kent (Champion and Power) ; 
London district and Bristol (Stephens) ; Bexhill, near Hastings, rare (Butler) ; Lea- 
sowe, near Liverpool, adhering to floating chips in pools (Chappell), 
According to M. Bedel this species is so closely allied to Rhinoncus 
denticollis that it can only be distinguished by the six-jointed funiculus 
of the antenne and the fact that the prosternum is very narrow between 
the anterior coxee. 
BARINA. 
This is rather an important tribe, containing a considerable number 
of genera and species ; they are, however, more characteristic of tropical 
than of temperate countries; according to the European catalogue of 
Heyden, Reitter and Weise, four genera and fifty species are found in 
Kurope, of which forty-seven belong to the genus Baris ; M. Bedel, 
however, separates off B. T-album as a distinct genus Limnobaris and 
says (1. c. p. 182) that, independently of Lissotarsus, Herbst., the tribe 
is only represented in Europe by two genera, Limnobaris and Baris ; the 
following are some of the chief characteristics of the tribe ; body more 
or less elongate, oblong, usually without or with very scattered scales 
above ; rostrum not received in a pectoral groove, never very long or 
slender, as a rule rather short and stout, antenne short and robust, with 
a rather large oval or oblong-oval club; prosternum not excavate ; 
elytra on the underside cut off from thorax by the side pieces of the 
mesosternum ; anterior coxe distant, posterior cox not globose, reach- 
ing the episterna of the metasternum; tibize armed witha strong curved 
hook ; tarsal claws simple. 
M. Bedel, in separating off his genus Limnobaris, divides it from 
Baris on the following characters. 
I. Pygidium invisible; head without any line of de- 
marcation between the front and the rostrum ; second 
joint of the funiculus of the antennz plainly longer : 
fhanthe third joint) <". 5 .. 12 «= se, 30). SuIMNOBARIS, Bedel. 
II. Pygidium exposed; head with a transverse line at 
the base of the rostrum; second joint of the funiculus 
of the antennze about equal to the third joint. . . Baris, Germ, 
LIMNOBARIS, Bedel. 
The species which has been adopted by M. Bedel as the type of 
this genus is spread over the whole Palearctic region; it is always 
found in damp and marshy places among reeds and rushes ; it is common 
in some districts in cold weather in the spathules of the bulrush ; 
according to Von Heyden it lives on Cladium mariseus, but it is 
apparently attached to several other Juncacew and Cyperacee ; the genus 
approaches Centrinus in the fact that the pygidium is entirely covered by 
the elytra ; this latter genus, which is considered a separate tribe by 
Lacordaire and Leconte, contains upwards of two hundred species 
which are confined to North, Central and South America,
