Slaterobius chisos 0

Slaterobius insignis

Identification: resembles large active ants and moves in an ant-like fashion

Sphragisticus nebulosus

Slater (1974) considers S. nebulosus a Holarctic element in the Northeast fauna; in the same list he clearly indicates other species as "introduced". I don't know why he and Dick might have thought otherwise a few years later ( 3 ) . Slater also stat

Trapezonotus arenarius

Identification: « the females have entirely black antennae and legs while the males have the fore legs, basal two-thirds of the mid and hind femora and the basal antennal segment orange-brown (ferrugineous). »

Xestocoris tibialis

Identification: Male readily distinguished by the greatly expanded fore tibiae. Based on details in O'Donnell's redescription of both X. tibialis and X. nitens , the females of X. nitens may be distinguished by the more obscure outer border of the cl
