48 ICHXEUMOXID.!. 



stigma and longer basally than apically; fenestrse minute and 

 broadly discreted; recurrent nervure hardly sinuate; lower wings 

 with the first recurrent strongly postfureal. 



Range. Europe, Sikkim, Burma, Japan, Malay Archipelago, 

 Tasmania, Texas, Canada. 



The head, thorax, and legs resemble those of EphtaUct, but 

 the abdomen aud wings are more similar to those of certain 



OPHIONIN-S. 



This genus, a $ of which is figured by Ratzeburg (Ichn. lorst. 

 iii, p. 94), was placed by Gravenhorst under Banchiis and originally 

 contained females only,' since he erroneously relegated the males to 

 his Ophionid genus Macrus. They were united by Wesmael, in 

 his " Notice sur les Ichneumonides de Belgique appartenant aux 

 genres Metopius, Banchus et Coleocentrus" in 1849, in which he 

 states the opinion that they belong rather to the PIMPLIN.E. 

 Thomson retains the genus in this position on account of the 

 oblique incision of the basal segments, though indicating the 

 affinity shown with the OPHIOXIN.S by the apically compressed 

 abdomen.

Coleocentrus mollerii, Bingham, Journ. Bomb. Nat. Hist. Soc. 1898, 

 p. 116, pi. A, tigs. 4, 4a, 



A very large black species, with profuse flavous markings. 

 Head black, with the clypeus, face below antennae, a dot at the 

 frontal orbits, and the cheeks flavous ; vertex with a few shallow 

 punctures. Antenna elongate and filiform, with the scape intu- 

 mescent, flavous beneath and deeply emarginate externally ; 

 fl:igellar joints apically oblique. Thorax black, with the pronotum 

 anteriorly and at its hind lateral angles, two short discal stripes on 

 the oval,* convex and transversely rugose mesonotum, mesopleurae, 

 the whole of the laterally flat, posteriorly rounded and apically 

 obliquely sloped metanotum, and large spots on the metapleuraB, 

 flavous. Scutellum punctate with its base, and a dot on either 

 side, flavous* ; postscutellum very small and compressed. Abdomen 

 nitidulous, with all the segments flavous- banded before the apex, 

 the basal ones depressed and deplanate, the apical subcompressed ; 

 the two basal segments discally glabrous, the remainder finely 

 punctate above at the base ; flavous bands of the fourth and 

 fifth segments laterally dilated, that of the sixth modified into a 

 transverse diamond shaped spot ; terebra a little longer than one 

 and a half times the length of the body (51 millim.), with the 

 valvulae ferruginous. Legs black ; the front ones with the coxa? 

 and trochanters apically, the femora in front, and whole of tibiae 

 and tarsi, flavous ; posterior legs with coxal spots, the trochanters 

 huskily, the intermediate femora externally and apically, the apical 

 half of the hind ones, the apical half of the intermediate tibia3 and 

 the centre of the hind ones, flavous ; posterior tarsi ferruginous.
