378 RHYNCHOPHORA. \_Phytobius. 



Marshy places ; on aquatic plants, especially Polygonum amphibium ; 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 thfe antennae and the fact that the prosternum is very narrow between 

 the anterior coxae. 



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 

 Europe, of which forty-seven belong to the genus Saris ; M. Bedel, 

 however, separates off jB. 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 Saris ; 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, antennae 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 coxae distant, posterior coxae not globose, reach- 

 ing the episterna of the metasternum ; tibiae armed Avith a 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 antennae plainly longer 



than the third joint LiMNOBAEis, Bedel. 



II. Pygidium exposed ; head with a transverse line at 

 the base of the rostrum ; second joint of the funiculus 



of the antennae about equal to the third joint . . . BARIS, Germ. 



X.IXVXNOBARIS, 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 mariscus, but it is 

 apparently attached to several other Juncacece and Cyperacew 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.
