College, Amherst,

THe. new species described in the present instalment are allfrom New Zealand, where they were collected in tile North
Island by Mr. Thomas It. Harris, in the South Island by
Messrs. Gourlay, Harris, Howes, and Tapley, and in Stewart
Island by Mr. Norman J. Jensen. My deep thanks areextended to all of tile above-mentioned students for theprivilege of retaining the type-specimens of the species
described.

J)icranomyia ~Zelandoglochina) paradisea circumcincla,

Male.--Length 8-9 ram. ; wing 8"8-9"5 ram.
Generally similar to the typical form, differing asfollows :-Mesonotal prmscutum with the median stripe darker andmore conspicuous ; scutal lobes darkened ; postnotal mediotergite blackened medially. Legs with the fore femora

Wings with the pattern more extensive, the apex narrowly
seamed with brown ; vein C, in cell M with a conspicuous
