Unknown Beetle 4 is Carabus nemoralis M=FCller, a large introduced =20
European ground beetle first found in North America in NB in 1870 and =20=

in NS in 1924. A very useful garden species, it preys to an important =20=

degree on slugs and earthworms.

The next three URL's (below) all go to this same image, but the next =20
picture in the sequence, Unknown Beetle 3a is also a ground beetle =20
(in the Carabidae), quite possibly Poecilus l. lucublandus (Say) (I =20
can't quite make out enough detail to be sure). It's a common and =20
widespread native species in Nova Scotia that are predators on a very =20=

wide variety of insects and invertebrates.

  Unknown Beetle 3 is also of Carabus nemoralis.

  Unknown Beetle 2 is a female Dytiscus verticalis Say, one of the =20
large species of predaceous Diving Beetles (Dytiscidae). The females =20
have prominent grooves on the elytra, the better for the males to get =20=

a grip on them when mating!

  Unknown Beetle 1 is a tiger beetle (Cicindelinae). It looks to me =20
like Cicindela l. longilabris Say, but Derek may want to comment =20
further.

Hope this helps.

Cheers!

Chris
