CYMBIODVTA, Bedel. 



This new _<rerms, provisionally iudicatcil l)y j\I. Pandelle, and after- 

 wards established by M. Ik-del, contains at present two or three species 

 from Europe and the United States, which, according to M. Bedel, are 

 distingiushed from PhiUi}jrlnis by the shape of the mesosternum and the 

 absence of a border at the base of thorax ; Dr. Sharp, however, has 

 pointed out that this genus and also the genus IlijiJrocomhus (which is 

 near P/ii/Iii/dyus) differ from the othtjr Hydrophiliiue as at present 

 known, in having the intermediate and posterior tarsi truly (and not 

 appanmtly as is often the case) four-jointed ; the pseudo-basal joint of 

 tlie maxillary palpi is also very slightly bent in such a manner that when 

 extended the curve of the joint is concave in front or inwardly, whereas 

 in Pliilln/dnis it is in the opposite direction. 



C. ovalis, Thorns. {mar(jindluf<, F.). Oblong-ovate, moderately convex, 

 a little di'pressetl on disc, unicolorous black with the sides of thorax and 

 elytra more or less distinctly redilish ; \ipper surface closely and dis- 

 tinctly punctured ; antenme and maxillary palpi ferruginous, joints of 

 the latter lighter at apex ; legs black or pitchy black, tarsi testaceous. 

 L. 4— ii- mm. 



Katlier common and widely distributed in the London district and the south of . 

 Enjjlaud ; also occurs in the CambriOecsliire Kens; there aiijicars, however, to be 

 no record of its capture from further north than Askhain V>{y^, «hrro I Lave taken it 

 not uncommonly. 



ENOCKIiUS, ThuiiiSMU. ' 



This genus is included by many authors umhn- PliUhijJrus, and per- 

 haps it would be better not to separate it from that genus ; the relative 

 length of the last joints of tlie maxillary palpi is the chief cJiaracter In' 

 which it is distinguished. 



E. bicolor, (ivll. {mdanoeepJiciIus, ()\., (i//-irrqnl/us, Steph.). Oval 

 or oblong-oval, convex ; upper surface closely and distinctly punctureil ; 

 head bhick with a yellow spot on each side? above eyes; maxillary iialpi 

 t(!staceous with second joint sometimes (doudeil and with apex of last 

 joint l)lack ; thorax and elytra rather brightly testaceous, the latter with 

 more or less-distinct traces of rows of larger punctures ; legs ami under- 

 side black, tarsi and apex of tibiic somewhat lighter. L. 5-5.^- mm.
