--Apple-Mail-151--367829750 Content-Transfer-Encoding: quoted-printable Content-Type: text/plain; charset=WINDOWS-1252; delsp=yes; format=flowed Hi Dave, Indeed, they have huge coxal plates on the meta-sternum which hide =20 the base of the hind legs. There are only two genera (Eucinetus and =20 Nycteus) to contend with in this region (Euscaphurus is in the =20 Pacific northwest and Tohlezkus is in the American south), and three =20 species: Eucinetus morio LeConte Eucinetus terminalis LeConte Nycteus punctulatus (LeConte) The keys to these are as follows: 1. Elytra punctate . Nycteus punctulatus - Elytra with fine transverse strigae or wrinkles. (=96> Eucinetus) 2 2. Hind tibia with 2 spurs. Eucinetus morio - Hind tibia with 1 spur. Eucinetus terminalis Additionally, E. morio is usually piceous or reddish brown with the =20 head and pronotum with a distinct reddish tinge, whereas E. =20 terminalis is black with the apical 1/4 of the elytra testaceous, so =20 the colour patterns are very distinctive. I have scattered records of =20= all three species from around the province (only E. terminalis in =20 Cape Breton so far), but no previous records from Kings County. E. =20 terminalis is also found on Sable Island. They are found in detritus or under fungus-covered bark of trees =20 where they feed on funal hyphae and on slime molds. For those =20 interested there are a couple of good images located at: http://www.zin.ru/animalia/Coleoptera/images/eucibico.jpg http://www.sbnature.org/collections/invert/entom/img/1811eucinetus.jpg Neat beetles!
