Art. XXVII.— Description of a new Dipterous Insect. By G. Vernon Hupson.

[Read before the Wellington Philosophical Society, 9th December, 1882.] 
Tus species is parasitic in the common magpie moth (Nyctmera annulata) ; 
it makes its way out of the insect when in pupa by boring a hole in the 
hard shell before turning ; the pupa of the fly is dark-brown, with scarcely 
any trace of articulations; it remains in that state about six weeks. 
Nemorea nyctmerianus, sp. nov. 
Body black with numerous black hairs and bristles; head with a broad 
longitudinal furrow between the ocelli extending downwards towards the 
base of the antennz, covered sparingly all over with black bristles. Eyes, 
reddish-brown, with a slight golden pubescence. Proboscis black, slender, 
covered at the tip with tawny 
bristles ; palpi deep black, with 
one or two short hairs. An- 
tenne less than three-fourths 
the length of the face, jet-black 
throughout, destitute of hairs, 
third joint about twice the length 
of the first and second together. 
Style black. Thorax dull black, 
with many long black bristles 
round the sides and beneath. Scutellum dull ferruginous, darker towards 
the mesonotum, armed with several long spines at the sides. Abdomen 
oval, broader than the thorax and about as long, black with faint bluish 
reflections ; along the anterior margin of the segments there are indistinct 
grey bands, which are crossed by a similar one running down the middle 
of the abdomen, the whole of which is covered with shallow black punctures, 
out of which short hairs rise; long bristles are present on the posterior 
margins of the abdominal segments in the centre and sparingly on the sides, 
becoming very numerous towards the apex. Legs rather long and slender, 
black, the tibiæ fuscous, clothed with short bristles ; foot-cushions small, 
light-brown. Wings hyaline, clouded with tawny towards the base; ribs 
black, becoming brownish towards the base. Scales pearly-white, sub- 
opaque. 
Length, 3 lines. Expanse of wings, 54 lines.
