Trichocnemis spiculatus? and unid. egg cluster - Trichocnemis - Female
Merritt College, Oakland, Alameda County, California, USA
December 1, 2011
Size: 55mm+
Found this beetle on the asphalt in the parking lot around 11:00 p.m., the night after the previous night of very strong winds. It had some sort of egg cluster attached to the side of its abdomen. That side appears to bulge a little compared to the other, when viewed from the ventral side. I'll post the eggs separately also.
The pronotum has two "dimples" on the upper part. All along the sides of the pronotum are small spines. If I'm counting correctly, there are 11 antennomeres.

These are the egg images:
