MACROCENTRIN &. 
ZELINI. 
Zele melanonotus, sp.n. 
Ferruginous, the head, pleure and breast largely tinged with pallid yellow ; 
a stripe across the vertex through the ocelli and the mesonotum, except the 
sides of the middle lobe, black, the antennz dark brown, darker coloured above, 
the scape except above pallid yellow, the head yellow, the orbits paler in tint ; 
legs testaceous, tinged with rufous, the coxee paler, the hind tarsi infuscated ; 
wings hyaline, iridescent, the costa and stigma testaceous, the nervures darker 
coloured, the basal almost black, the transverse median nervure received shortly 
beyond the transverse basal; the recurrent nervure received in the middle 
of the cellule ; the basal abscissa of cubitus oblique, roundly curved, the 2nd 
straight, the basal abscissa of radius straight, obliquely sloped, about one 
quarter shorter than the 2nd; the Ist transverse cubital nervure straight, 
sharply obliquely sloped, as long as the 2nd abscissa of the radius and one- 
fourth longer than the 2nd, the apical half of the anal nervure roundly curved 
downwards on the basal half, upwards on apical. Female. Length 12 m.m. 
Base of metanotum irregularly punctured, the rest irregularly transversely 
striated. First segment of abdomen fully one-quarter longer than the 2nd ; 
distinctly narrowed and of equal width behind the spiracles, becoming gradually 
widened, but not much, from these. Tips of mandibles black, palpi pilose, 
long, reaching to the middle coxe. Sheaths of ovipositor short, hardly reach- 
ing to the top of the penultimate segment. 
METEORIN2. 
Erythrometeorus. 
Wings with 3 cubital cellules, the 2nd oblique, 3 times longer than wide, 
rounded at the base, receiving the recurrent nervure close to the base ; stigma 
large, receiving the radius before the middle ; the radial cellule not reaching to 
the apex ; the basal abscissa of the radius short, straight, forming a blunt angle 
with the 2nd, which is not half its length ; transverse median nervure received 
shortly beyond the transverse basal ; anal nervure interstitial ; the 2nd discoidal 
cellule closed. Clypeus separated from the face by a furrow, its apex trans- 
verse. yes oval, malar space slightly longer than them. Vertex and cheeks 
not margined. Thorax short, wide, reticulated, without parapsidal furrows ; 
the mesonotum rounded at the base, the metanotum steeply sloped, its sides 
broadly rounded. Abdomen with a slender peduncle, one-third of the total 
length, its apical third dilated, the spiracles placed at the base of the latter ; 
the rest of the abdomen forms a longish oval ; the 2nd segme nt is as long as the 
petiole and longer than the other segments united. Legs normal, the spurs 
short. Antenne stout, shorter then the body, 18-jointed, the 3rd joint longer 
than the 4th ; they are placed above the middle of the face. Mandibles with a 
long, curved apical tooth, the sub-apical with its apex transverse, clearly 
separated from the apical. The marginal cellule in the hind wings is not 
divided by a nervure and is narrowed towards the apex.
