Explanation of Names
pice (L). 'pitch black' (1)
6 spp., all Nearctic (2)
23-32 mm length (large) (3)
A large, "polished black" click beetle (3). Blatchley (4) describes this species:
Striae on disk of elytra not at all impressed, their punctures very fine and separated one from another by more than their own diameters; intervals flat, very minutely and indistinctly punctulate (from key)....Elongate, subdepressed. Black, strongly shining; antennae and tarsi piceous. Thorax a little longer than broad, slightly narrowed in front and at base of hind angles; sides feebly curved, strongly margined; disk finely, sparsely and shallowly punctate, more densely at sides. Elytra with sides parallel to middle, thence feebly narrowed into a rounded apex (description).
(Note that this historical reference should not necessarily be relied on for keying, but the narrative description should be valid.)
e US (TX-GA-NY-NE) (5)
Dillon and Dillon state "adults "found beneath stones and rubbish in dry locations" (3). (They are almost surely quoting Blatchley (4).) Observed in Piedmont of North Carolina common on vegetation in moist bottomland forests (personal observation, May 2010, see caption to photo).
mostly May-Jun (4)(6)(BG data)
