NEW CHALCIDOID HYMENOPTERA. By A. A. GiRAULT, Bureau of Entomology, U. S. Dept. Agriculture. 1. Mirzagrammosoma new genus of the EJachertini. Female: With the habitus of Zagrammosoma Ashmead but the scutellum without grooves, the vertex more elevated, elevated nearly for the length of the eyes which thus appear to be in the middle of the side of the head, the cheeks a little longer than the eyes. Antennas inserted about in the middle of the face, the scape compressed (about three times longer than wide at apex), also the funicle and club, as in the named genus but there are two short ring-joints. Mandibles 6 — dentate. Submarginal vein distinctly broken in regularity, distinctly longer than the marginal, the postmarginal two-thirds its length. Club not very distinctly jointed. Hind tibial spur distinct, not large. Parapsidal furrows rather long, meeting the small axillae which are nearly entirely cephalad of the scutellum. Pronotum conical, as long as the scutellum which is about two-thirds the length of the scutum. Propodeum a little shorter than the scutellum, with a delicate median carina and no others, the spiracle very minute. Abdomen sessile, as long as the thorax, conical. Cephalic coxse elongate. Elachertine in appearance. (1) Mirzagrammosoma lineaticeps new species. Female: Length, 2.05 mm., slender. Purplish black, the legs except the hind femora and tibiae (except the latter at tips) and head pale yellow (middle and hind coxae not seen) ; a narrow pale yellow line down two-thirds of the pronotum from cephalic margin, latero-dorsad and ventro-laterad (total of four lines). Meson of proventer caudad broadly golden yellow. A broad black line down middle of the face from vertex to clypeus and another across the vertex and down each side to the eyes and then from the ventral ends of the latter to the end of the head across the cheek. Mandibles pale yellow, reddish at tip. A pale golden line up the lateral margin of the axilla and along the scutum some little distance beyond (cephalad). Thorax finely scaly, the propodeum glabrous; abdomen delicately scaly. Fore wing with the following remarkable pattern, the venation black except the pale postmarginal vein: A long cone-shaped black marking orig-inating near base in an acute point, running clavately up the center of the blade and a little distad of the apex of the postmarginal vein obliquing up to the cephalic margin just before the apical turn, the obliqued portion narrowing cephalo-distad ; a rather narrow apical black stripe (but absent from the cep halo-distal fourth of the apical margin) ; an oblique (cephalo-proximad) , rather narrow stripe from the first long marking at a little before its elbow to the base of the stigmal vein and entirely involving that vein; and another similar stripe but much 279
