Icaria nigra, Smith (1858), var. catiiarinse {Ca.m..) = AncistrocerHs 



catharince, Cam. (1913). 

 All the species published with the specific name " catharince " 

 in Cameron's paper on the Waigiou Hymeuoptera (Bijdr. Dierk. 

 viii. pp. 76-86, 191.3) bear labels with the specific name " heau- 

 forti " on the type-specimens. The var. catharince differs from 

 the type in having the following yellow facial markings : — a 

 bilobed mark between antennae at base, a mark on lower orbits 

 on each side, and two apical marks on clypeus. There is a 

 specimen in the British Museum from Aru (Coll. W. W. Froggatt) 

 which agrees with the type in the Amsterdam Museum.
