Camponotus castaneus Waking Up
Along with having only one waist segment (note the ant in the lower left) Camponotus also have a domed mesosoma (thorax or middle section) with the three segments almost forming a smooth curve. This is the only color they come in too, the head is typically darker than the rest of the body but never black the way it is in C. americanus which also tends to have black all over it's body around joints especially.
A Field Guide to the Ants of New England lists their common name as "The Chestnut Carpenter Ant"
