Section IV, (Sub-Gen. Bisochara, Thorns.) 



This section contains one species, the very distinct 0. longiuscula, Er., 

 which may at once be separated by its very long antennae, Avhich reach 

 the apex of the elytra, and are strongly thickened towards their extremity: 

 it occurs in marshy places, at roots of grass, &c., and is often abundant 

 in flood refuse. 



O. long-iuscula, Er. {elongata, Aube, procerula, Mann.). Rather 

 narrow, very finely and thickly pubescent, dull black or pitchy brown ; 

 head distinctly punctured, antennaj long, entirely ferruginous, or pitchy 

 with base lighter, second and third joints nearly equal, 4-10 gradually 

 thicker, fourth smaller than fifth, tenth rather longer than ninth ; none 

 of the joints, however, are really transverse ; thorax broader than long as 

 broad behind as elytra, very finely punctured ; elytra almost square, 

 longer than thorax, finely, thickly, and somewhat rugosely punctured ; 

 hind body long, with sides parallel or slightly rounded to fifth segment, 

 and thence gradually and slightly naiTowed towards apex, with the three 

 first segments strongly and evenly impressed at base, very finely 

 punctured and pubescent ; legs testaceous, posterior tarsi nearly as long 

 as the tibiae with the first joint very long, plainly longer than the three 

 following together ; the colour is somewhat variable, the thorax and 

 elytra being often of a reddish brown colour. L. 3-3| mm. 



Male with the ventral plate of seventh segment of hind body produced 

 into an obtuse angle in middle of apical margin, and with the last joint of 

 the antennae distinctly longer than the two preceding : in the female the 

 last joint is plainly shorter than the two preceding. 



Common and generally distributed in Enisrland, and probably in Ireland. Scotland, 

 common. Lowlands, in swamps, Tweed, Forth, and Solway districts; in Fiance it 

 appears to be somewhat rare, and to prefer northern and mountainous regions. 



Section V. (Sub-Gen. Disochara, pars. 1 ) 



This section contains one species, 0. rupicola, Rye, which is considered 

 in the catalogue Heyden-Reitter-Weise as synonymous with 0. tirolensis, 

 Gredl., and is classed with longiuscula, Er., Ju(/uhris, Kraatz, and other 

 species, under the sub-genus Disochara, Thorns. : Mulsant and Rey 

 consider 0. luguhris, which evidently bears a close relation to 0. rupicola, 

 as belonging to their sub-genus Podoxya, but as interniediate betw^een 

 Section I. (as above given) and the other sections ; as, however, from the 

 descriptions it appears evident that 0. luguhris with its parallel form 

 cannot properly belong to Podoxya as strictly defined, 1 have preferred 

 to place 0. riqncola in a section by itself ; it might perhaps be classed 

 with 0. longiuscula, but its antennae are much shorter, and have the 

 third joint shorter in proportion to the second joint.
