Sternites 2–6 mostly brown; with elongate yellow pollinose patches in posterolateral corners sometimes nearly meeting at midline; with some long, slender, apically crinkled, brown hair-like setae, especially dense on sternites 5–6.

Discussion. Mr. David Notton of the Entomology Department, BMNH, kindly examined the holotype and provided digital photographs. The northeastern C. fasciatus is readily distinguished from the more western C. cruciatus by the deep golden pollinose face and bronze mystax (white to pale yellow pollinose face and white to pale golden mystax in C. cruciatus); black or dark brown hair-like setae on postgena, stipes, and plapi (white in C. cruciatus); absent or poorly developed pale pollinose spots mesad to the postpronotal lobes (well developed in C. cruciatus); mostly polished black male abdominal sternites with narrow, medially divided, yellow pollinose bands along the posterior margin (mostly white pollinose sternites in male C. cruciatus).
Malloch (1917) described and illustrated larvae and pupae under the name C. cruciatus. They were collected in Maryland and therefore must be C. fasciatus rather than the more western C. cruciatus. Bromley (1946) listed C. fasciatus (as C. cruciatus) as a woodland species of Connecticut’s oak and mixed mesophytic region. He reported finding it in brushy pastures or edges of fields or woods, frequently alighting among blackberry thickets or in wild indigo (Baptisia). “It flies rather heavily with a loud buzz. Its prey consists largely of small beetles [rose chafer, Macrodactylus subspinosus (Fabricius)] and other slow-flying insects. While feeding, this species suspends itself from a twig or leaf with a front foot, holding its prey with the others, in a manner similar to that of Diogmites.”
Petch (1934) reported Ceraturgus cruciatus from Montreal at the time when C. fasciatus was considered a junior synonym.
Of 16 specimens that I have seen pinned with presumed prey, six are pinned with scarab beetles, four with other beetles (meloids, elarterid, chrysomelid), three with ants, one with a sphecid wasp, one with a cercopid, and one with a stink bug.
