Notes on African Chalcidoidea—IV

Extract

♀ The entire integument of the head and body metallic and shagreened, or highly raised reticulate; the abdominal tergites being a little smoother. Head in profile triangular, from above somewhat thin, shallowly concave across the frons, rounded behind the eyes from vertex to genae; but medianly, behind the raised ocellar traingle, there is an inconspicuous ridge before the occiput; from in front, exceedingly wide, the scrobes set close together in the middle of the face, well above the base line of the bare eyes. Labrum long, spade-shaped, conspicuous; mandibles similar, bidentate, a little asymmetrical. Antenna thirteen-jointed, with simple cylindrical joints; the divisions of the club indistinct. Thorax much swollen; pronotum almost concealed behind the head; nearly separated into two tergites; prosternum posteriorly truncated, triangular; mesonotum with the parapsidal furrows fine and hardly traceable. Axillae quadrate, touching, or only separated narrowly (?). Scutellum with a transverse suture before the unarmed, rounded apex; mesopleural femoral furrow well-marked, and the prepectus rather large. Wings: forewings with the post-marginal almost obsolete; radius very short, with a terminal group of clear cells instead of the usual linear arrangement. Hind wings with the submarginal cell long and wide. Legs: fore coxae long; hind tibiae bicalcarate without apical comb. Abdomen sessile or practically so; broad, depressed and broadly concave above; very shortly carinate (basal one-third) below. The first tergite (which with ii. and iii. is posteriorly, medianly notched), covers threefourths of the surface; tergite ii. reaches the edge; the third is on the edge; while tergites iv., v., vi., vii. are all ventral in position. The ovipositor is broad, stout, with strong teeth on the needles and central piece.
