350 NEW ZEALAND AMD AUSTRALIAN PARASITIC HYMENOPTERA, 



scutellum, a spot on metopleura just above hind coxa*, first seg- 

 ment of abdomen, a band at base of second and third segments, 

 a narrow band at apex of third and a large band at apex of 

 abdomen yellow or yellowish-white; legs rufous, anterior coxae 

 and trochanters, middle coxa-, a moderately broad annulus near 

 base of hind tibiae and basal joint of hind tarsi, except apex, 

 white; tips of hind femora, a narrow annulus at extreme base of 

 their tibiae, before the white annulus, the rest of tibiae and tarsi 

 black. Wings hyaline with a large fuscous cloud at apex, veins 

 black. 



Head narrowly transverse, smooth, impunctate; thorax rather 

 closely punctate, without parapsidal furrows; metathorax closely 

 rugoso-punctate. 



Type—No. 4904, U.S.N.M. 



Hob. — Australia (A. Koebele, collector). 



Tribe ii.— Labenini. 

 This tx*ibe is represented by only three genera — Labena, Grotea 

 and JYonnus, Cresson. It is not yet recognised outside of the 

 American fauna. 



Tribe Hi.— Lissonotini. 

 Genus Euctenopus, Ashmead, n.g. 



This new genus falls in next to Phytodietus, Grav., so far as its 

 metathoracic characters are concerned, and in having no trans- 

 verse apical carina, but differs greatly in other chai*acters. The 

 two compared may be easily separated by the following diagnoses : 

 a. Transverse median nervure in hind wings 



broken below the middle ; eyes not quite 



extending to base of mandibles, the malar 



space being fully as long as the pedicel ; 



submedian and median cells in front wings 



equal Phytodietus, Grav. 



an. Transverse median nervure in hind wings 



broken at or a little above the middle; eyes 



extending to base of mandibles, without a 



malar space; submedian cell in front wings 



distinctly shorter than the median Euctenopus, Ashm., n.g.
