HYMENOPTERA FROM SARAWAK. 129 
flagellum covered with a microscopic pile; the wings clear 
hyaline; the nervures and stigma black: ocelli larze, and ina black 
patch; the parapsidal furrows striated on the apical half; the 
metanotum shagreened and obscurely transversely striated. 2. 
Length 9 mm. 
Hab. Kuching. 
There is a distinct keel on the metapleurze above the 
middle; a roundly curved one on the apex of the metanotum: 
the hinder tibiz are long, compressed and reach near to the apex 
of the petiole; it is distinctly narrowed at the base behind the 
spiracles, which project; it is as long as the 2nd and 3rd joints 
united. The marginal cellule is not divided,in the hind wings, 
by a transverse nervure. 
AGATHIDINA. 
Balecemena, gen. nov. 
Areolet narrowed at the top, the nervures, however, not 
touching. Second transverse cubital nervure without a process. 
Radial cellule long and narrow. First cubital and first discoidal 
cellules not separated. Front not much depressed and without 
keels ; there are two short keels between the antenne. Central 
lobe of mesonotum raised; the parapsidal furrows indistinct. Apex 
of scutellum with a stout transverse keel. The base of the median 
segment obliquely depressed; there are two longitudinal keels 
which forma closed longitudinal narrow area in the centre, 
these being the only keels on it. All the claws are bifid. The 
ovipositor is short; its sheaths broad. ‘The antenne are longer 
than the body and taper towards the apex; the basal joints of 
the flagellum are equal in length. The apical three joints of 
the maxillary palpi are not lentical or compressed and are not 
much shorter than the basal. 
May be known by the long, narrow wings, with the long 
cubital and raidal cellules in both wings, by the very short 
ovipositor which hardly projects, by the single central area on 
the median segment, by the short, raised, distinctly separated 
middle lobe of the mesonotum, which does not reach to the 
middle, and by the long antenne and hind legs.
