This interesting crane-fly is named after its collector,
Mr. E. S. Gourlay, to whom the writer is indebted for muchinteresting material from Banks Peninsula and the vicinityof Christchurch. The strict get,eric position of this very
isolated species must be considered as being in doubt. The
petiolate cell R~ would place the fly near EriolJtera, and it isnew or little-k~own Tipulidw.

possible that more material will demonstrate that a newgroup is neeess~,ry for its reception. A slight proximad
shifting of the base of vein R~ would make a Molophilas ofthis species, as far as venation is coneem~ed, but the male
genitalia are not of the strict Molophitus type. The antenna;
somewhat resemble those of species of Amphineurus of theinsu[sus group, but are even more like those of Molojohilus
quadrifidus, Alex.

Genus XENOSlA,Malloch.
I erected this genus for the reception of one species,
un#ulata, Stein. In my original definition of the genus, iincluded the presence of fine hairs on the upper marginof the hypopleura in front of the spiracle as one of thecharacters of the genus. This applies to the genotype,but not to morosa, Stein, which I consider may properly
be located ill this genus. This character, therefore, must be
eliminated.
