Fore wing as long as body. Pterostigma ( Fig. 142 ) nearly 2.7 times as long as wide and issuing r slightly proximally from its middle; r just one-third shorter than width of ptertostigma; 3-SR 1.65 times as long as 2-SR, SR1 straight, 1.3 times longer than 3-SR and approaching tip of wing; 1-R1 clearly 1.5 times length of pterostigma ( Fig. 142 ). First discal cell fairly high, 1-M twice as long as m-cu, the two veins parallel with each other; 1-SR-M just bent and 1.26 times length of 1-M ( Fig. 143 ).

First tergite ( Fig. 144 ) broad, i.e. as long as broad behind, pair of spiracles near before its middle, beyond spiracles almost parallel-sided. Second tergite 3.1 times as wide behind as long laterally and as long as third tergite; suture between tergites 2-3 bisinuate, deep and almost smooth. Every tergite polished. Hypopygium pointed, ovipositor sheath long, as long as hind tarsus + tibia + two-thirds of hind femur ( Fig. 145 ).

Ground colour of body blackish brown to black with much reddish yellow to testaceous pattern. Oral organs with palpi brown. Light coloured: margin of eye and cheek, pronotum, imaginary line of notaulix, tegula, tergites laterally; sternites yellowish. Legs brown; light to yellowish brown: fore tibia + tarsus, proximal half of middle tibia and proximal two-thirds of hind tibia. Wings brownish fumous, pterostigma brown with a great basal yellow spot, veins brown to light brown.

Variabile features of the female (22): Similar to the female lectotype. Body 4.8-5.2 mm, usually 5 mm, long. Antenna about as long as head, mesosoma and two-thirds of metasoma combined. Antenna with (22-)26-32(-34) antennomeres. First flagellomere 1.2-1.3 times as long as broad, further flagellomeres gradually shortening so that middle 12-16 flagellomeres subcubic to cubic, last 8-10 flagellomeres attenuating so that penultimate flagellomere 1.1-1.2(-1.3) times as long as broad. - Head in dorsal view usually 1.8 times, exceptionally 1.75-1.9 times, as broad as long. Hind femur (3.1-)3.3-3.6 times as long as broad medially ( Fig. 146 ). 3-SR 1.5-1.6 times as long as 2-SR. First tergite exceptionally either with broadening sides beyond pair of spiracles, or somewhat longer than broad behind ( Fig. 147 ), or slightly shorter than broad behind; second tergite exceptionally with fine longitudinal striation. Ovipositor sheath shorter than to as long as body. Colour of body usually as in lectotype, less usually ground colour of body reddish yellow to testaceous with a few dark pattern.

R e d e s c r i p t i o n of the male (12): Similar to the female. Body 3.5-4(-4.5) mm long. Antenna shorter than body and with 26-36 antennomeres. Flagellomeres either similar to those of the female or flagellomeres 1.3-1.4 times longer than broad. Head in dorsal view 1.7-1.8 times as broad as long. Hind femur 2.9-3.3 times as long as broad medially, nearly evenly broad. First tergite either as long as broad behind or 1.1-1.2 times longer than broad behind. Ground colour of body either blackish to black with light pattern or reddish yellow with dark pattern, rarely body (with legs) entirely black (melanic form).

R e m a r k s: Within the subgenus Glabrobracon the species B. hemiflavus is nearest to

B. lividus TELENGA and B. chrysostigma GREESE considering their more or less reddish

yellow body, form of first tergite and fairly long ovipositor sheath; the three species are

distinguished by the features keyed:

1 (2) Temple in dorsal view more or less receded ( Fig. 148 ). Claw more long and its basal lobe slightly more pointed ( Fig. 149 ). First tergite 1.1-1.2 times as long as broad behind, margin of scutum crenulate ( Fig. 150 ). Pterostigma brown to light brown, wings hyaline.: 3.5-4 mm ............................ B. (Gl.) lividus TELENGA 1936

2 (1) Temple in dorsal view rounded ( Fig. 137 ). Claw less long and its basal lobe less pointed ( Figs 141 , 151 ). First tergite of variable length, margin of scutum not crenulate ( Figs 144 , 152, 153 ).

3 (4) Second submarginal cell of fore wing less long, 3-SR 1.2-1.3 times as long as 2-SR, SR1 reaching tip of wing ( Fig. 154 ). Basal lobe of claw not pointed, large ( Fig. 151 ). First tergite 1.1-1.3 times as long as broad behind ( Figs 152, 153 ). Pterostigma yellow, wings subhyaline to faintly fumous.: 3-5(-5.5) mm................. ................................................................................ B. (Gl.) chrysostigma GREESE 1928

4 (3) Second submarginal cell of fore wing long, 3-SR 1.5-1.6 times as long as 2-SR, SR1 approaching to almost reaching tip of wing ( Fig. 142 ). Basal lobe of claw pointed, less large ( Fig. 141 ). First tergite as long as broad behind ( Fig. 144 ), exceptionally slightly longer ( Fig. 147 ) or broader. Pterostigma bicoloroured: brown basally with a great yellow spot ( Fig. 142 ).: 3.5-5.2 mm .............................. ...............................................................................
