Hammaniella relativa, n. sp. — Face and dorsum subopaque. punctured, front opaque, the pleura more shining, longitudinal raised line on metapleura distinct, terminated abruptly, the mesothorax not appearing sharply truncate. The longitudinal medial lines on meta-notum converging. % . — Length 14 mm. Clypeus with a few punctures, somewhat shining, transversely impressed, anteriorly though not strongly. Face closely punctured, front opaque. Cheeks impunctate on the eye margin, otherwise with distinct, small, separated punctures, shining malar space punctured, opaque. Dorsulum almost opaque, the punctures tolerably small, closely arranged. The scutellum more strongly punctured. Mesopleura shining, with well separated, to smaller closer punctures. Metanotum with converging, crude, longitudinal medial carinas becoming obsolete before the apical margin, transverse carina strong. Metapleura separated from the metanotum by a distinct raised line, which stands out prominently, being margined on each side by a more or less distinct channel. Wings subhyaline, with a dullish cast. Areolet imperfectly trapezoidal in form, the petiole shorter than any of its sides, one-half of the curved and longest side of the areolet, one-half of the second recurrent nervure and a short distance of cubito-discoidal nervure, hyaline; stigma and nervures almost uniformly light brown, base of the wings yellow. First dorsal segment strongly punctured, the spiracles distinctly produced, the succeeding dorsal segments becoming less and less punctured, to almost smooth.

Tegulas, one spot aside and below them, coxae and trochanters of four anterior legs, part of posterior coxa? and trochanters, yellow. On the posterior legs the greater part of femora, apex of tibiae and all of tarsi are more or less dark brown. Apex of first dorsal segment somewhat claret-brown, the second, third, fourth and greater part of fifth mostly ferruginous. Type : Coll. Am. Ent. Soc, Phila. Type locality, New Jersey.
