PLATE 37. 
Amonest a large collection of Diptera recently presented to me by 
Mr. J. W. Campbell, of Christchurch, is a most interesting new species 
of Tachinid, which I describe below in a new genus under the name of 
Campbellia campbelli. Not only has Mr. Campbell secured large numbers 
of valuable Diptera, but he is also an accomplished observer of the 
structure and habits of these insects, as is amply shown in his recent work 
on the adult and pre-adult stages of the Blepharoceridae.* m 
In 1911 Mr. E. H. Atkinson captured a second species, which was sent 
to the British Museum, and through the courtesy of Mr. F. W. Edwards 
the specimen has been submitted to me, and is herewith recorded under 
the specific name of cockaynei n. sp., named after Mr. A. H. Cockayne, 
Government Biologist. 
The extraordinary wing-development in these insects also occurs, only 
to a much greater extent;in the New Zealand Anthomyid Ezsul singularis 
Hutton. A tendency to this development to a less extent occurs mM 
several other species of mountain Diptera. 
Subfamily GYMNOSOMINAE. 
Genus CAMPBELLIA n. g. 
slightly below apex of wing; last section of fourth vein abruptly but 
evenly rounded upward to meet the third at right angle; posterior 01088 
vein about one and a third times its own length from the small cross-Veln 
which is a little beyond the middle of the discal cell; first vein meeting 
costa almost immediately above small cross-vein; veins bare, stoutly 
vibrissae, frontal bristles weak and short, extending to base есе 
antennal joint; otherwise parafrontals bare; post-orbital bristles weak, 
not extending below middle of posterior orbits. Proboscis rather slender, 
elongate; palpi well developed, slender but swollen apically.
