Type: Biconus atroruber Townes. 
Fore wing 4. 1-10. 2mm long. Wings hyaline with dark brown 
blotches. Female flagellum long and slender, not flattened below 
apicad. Male flagellum without tyloids. Mandible moderately long 
with lower tooth almost as long as upper. Clypeus 1. 5-2.0 as wide as 
long, moderately and asymmetrically convex or weakly and sym- 
metrically convex in profile; its apical margin subtruncate to a little 
convex and usually with a pair of often inconspicuous median 
preapical tubercles or swellings. Malar space: 0.72-1.0 as long as 
basal width of mandible. Pronotum with epomia sharp but not 
prolonged much dorsad or ventrad of scrobe. Mesoscutum with 
notaulus sharp but fine, reaching more than 0.6 the length of meso- 
scutum; surface mat with delicate puncto-reticulation and very 
dense, short setae. Mesopleuron has no ridge on prepectus below. 
Hind coxa with a strong and polished subvertical groove externo- 
ventrally near base. Female tarsus with 4th segment very deeply 
bilobed at apex. Wing venation: areolet large, symmetrically pen- 
tagonal, intercubiti gently to moderately convergent dorsad, 2nd 
abscissa of radius 1.0-1. 1 as long as 1st intercubitus; discocubitus 
broadly angled, ramellus well developed to vestigial; mediella defi- 
nitely arched; axillus close to and paralleling anal margin of hind 
wing; brachiella sometimes short or absent. Propodeum with spira- 
cle round to short-oval and with its apical trans-carina represented 
only by conspicuous ligulo-cuneate, ligulate, ligulo-conic or even 
conical cristae. First gastric tergite without a baso-lateral expan- 
sion; ventral longitudinal carina traceable but often weak or obso- 
lete on postpetiole and sometimes faint also on petiole; dorsal 
carinae more or less suggested toward apex of petiole and on base of
