On Two new Species of Bracon. 505 
Type Acentropelma spinulosum, F. Cambr. (sub Metrio- 
pelma). 
In Metriopelma, at least in the species that I refer to Breyer? 
and tetricum, there is no scopula, merely normal hairs on the 
surfaces above mentioned. 
To the synonymy of Metriopelma tetricum, Sim., must be 
added Miaschistopus rapidus, Poc., based upon specimens in 
the British Museum from Keyserling’s collection labelled 
W. Africa. The error of locality misled me into describing 
the specimens as the representatives of a new genus and 
species. 
LXX.—Description of Two new Species of Bracon from 
Bengal. By Col. C. T. Binenam, F.Z.8., F.E.S. 
My friend Mr. L. de Nicéville, Government Entomologist, 
Indian Museum, Calcutta, has kindly entrusted to me for 
identification two species of Lracon bred from the larvee of 
Scirpophaga aurifiua, Zeller, a moth belonging to the family 
Crambide, extremely destructive to the sugar-cane plantations 
in Bengal. So far as a careful examination of the material 
in the collections of the British Museum and of the very 
scattered literature on the subject have enabled me to judge, 
both the species sent have not been previously described. I 
have ventured to name one after Mr, de Nicéville. 
Bracon Nicévillit, sp. n. 
2. Fulvous yellow, the tips of the mandibles, the an- 
tenn, a broad band across the vertex of the head, the fifth 
and base of the sixth abdominal segment above, and the 
sheath of the ovipositor black, the ovipositor itself yellow, the 
posterior tibizs and tarsi fuscous: wings hyaline yellow, the 
apex of both and inferior margin of hind wing infuscated ; 
the front wing with two fuscous clouds, one in front of the 
basal nervure, passing from the costal margin of the wing 
through the discoidal cells, the other covering the apical half 
of the stigma and passing through the second cubital cell ; 
base of stigma yellow; a clear hyaline spot in the first 
cubital cell. Head and thorax smooth and shining; legs 
covered with ashort pubescence; a triangular impressed mark 
on the face above the clypeus slightly raised in the middle, 
with a small pit at each angle connected by furrows; a deep, 
short, impressed line vertically from between the base of the 
antenne to the pit at the apex of the triangle; the thorax
