eyes; (C) fore wing second submarginal cell showing relatively short vein 1-SR; (D) base of hind wing showing large glabrous area distal to vein cu-a; (E) hind leg showing dark mark on ventral surface of femur.

Material examined

Holotype. Female Philippines, “P.I. Palawan 6.4 km N. of Tarumpitao Pt., 30. V.1958 ”, “[caught] in jungle”, “ H. E. Milliron Collector. ” “ Holotype Ischnobracon gressitti Baltazar ′63” ( BPBM).

Morphology

Length of body 12 mm, of fore wing 11.5 mm and of ovipositor 9 mm. Antenna with 107 flagellomeres. Raised median area of first tergite not conspicuously depressed medially. Fore wing vein cu-a distinctly postfurcal. Second submarginal cell strongly expanded distally, vein 2-M 3.4 times longer than 2-SR. Base of hind wing with sub-basal cell largely glabrous and with large glabrous area distal to vein cu-a. Vein 1-SC+ R interstitial.

Colouration

Head yellow with square mark on face as well as mid-longitudinal stripe on upper part, frons medially and vertex and occiput black. Meso- and metasoma black except for a few dark brown-black marks and apical half of antenna which is brown yellow, fore and

middle legs which are cream yellow, the latter with distinct dark brown mark on coxa and baso-ventral part of femur. Wings smoky yellow with distal margin grey brown.

Notes

Closely related to I. laboriosus and I. albitarsus sp. nov. differing from both in being almost entirely black and in having the antennae yellowish distally.
