Silverstream, Wellington, February, 1899 (G. V. Hudson, No. 166c); 
type male in British Muse um; a second male in Cambridge Museum. 
Another specimen (damaged, tip of abdomen missing) in British Museum 
is almost certainly the same species, but differs as follows: Nasus indis- 
tinguishable, represented by a tuft of long black hairs only. Pronotum 
orange. Thoracic markings further reduced, postnotum without dark area 
in middle. Presented by Captain F. W. Hutton in 1902, and determined

Macromastix ferruginosa n. sp. 
Head reddish-orange, an ill-defined but large dark spot in middle. 
Front MM half as broad as head, somewhat swollen, a slightly bifid 
tubercle above antennae. Rostrum reddish-orange, about as long as head ; 
nasus black, rather long in the male, much shorter, a mere rounded 
projection, in the female. Palpi and antennae black. Flagellum eleven- 
jointed, joints nearly cylindrical, gradually and very slightly increasing in 
length to the fourth, then decreasing again; last four more slender and 
with more numerous hairs than first seven. Thoraz ferruginous ; à sier: 
darker central praescutal stripe, most distinct in female; apical margin 
of scutellum obscurely darker; a light-orange patch on pleurae extending 
from base of wing to prothoracic stigma. Abdomen with broad median

arrowly black, those of segments 2-4 in the male more broadly so:

Hypopygium mostly orange, its structure practically as in М. dux Legs 
black; coxae partly ferruginous; bases of front trochanters and front
