ALEXANDER.—Studies on the Crane-flies of New Zealand. 655 
of Christchurch, as discussed in the appended account, indicates that the 
type-locality is very probable. The fly has not been taken elsewhere. 
Allotype.—d. Length, 14 mm. ; wing, 2-5 mm 
esten as in female, differing as follows : Antennae 16-segmented, 
formula being 2--2--8--4; basal pectinate segments in spiral align- 
ment; pectinations short, the longest about three times length of segment 
that bears it. Head light grey, centre of vertex suffused with dark brown. 
Mesonotal praescutum pale brown anterior end of median stripe and 
face ы base with smooth hemiovate black ren Outer dististyle a flattened 
blade, broadest at base, apex on outer margin produced into conspieuous 
black spine, remainder of apex squarely truncated, not projecting beyond 
spine, margin weakly — te; outer dististyle without setae; inner 
dististyle slender, inner or mesal face near mid-length bulging and provided 
with setae, apex beyond this base slightly d Pb etre with numerous 
setigerous punctures and with a short stout s seta on inner margin. 
Gonapophyses slender, before mid-length bent portes upon themselves, 
"à часта expanded. Aedeagus slender, straight, base dilated, apex bifid.

This is the only species of Gynoplistia so o far described in which both 
sexes are nearly apterous. I am greatly indebted to Mr. Gourlay for the 
accompanying discussion of the conditions under which these flies were found. 
* This little lot is the result of one half-hour's collecting at the locality 
indicated on the labels in the bottles. The flies are fairly plentiful on a 
hot ped and are not only like harvest-spiders Sg reese in appearance, 
but also similar in their movements, each having the same peculiar 
springy y oak They ett in hanging on tall grass-blades without a move- 
ment, basking in the Associated with this species to-day were two 
other Tipulidae, the Medos abundance of the three being indicated by the 
followin: аар Gynoplistia Lng má 50 per cent.; Limnophila skusei, 
:35 per с vs. Hà lorusia novarae, 15 per cent. In their breeding-grounds 
the фал г is a ioa black, peaty ам, and though wet is not slimy. The 
river (Avon) flows through the centre of the city and the locality is about 
five minutes’ walk fr he Square. This is the only locality from which 
I have collected this аби [to which was later added Johnson's Fish-pond, 
Opawa, Christchurch—a single male on 12th February, 1922], and this 
icular stretch is about 100 yards long by 2-5 yards in width at its broadest 
. point, so they seem to have a range. I have not observed particularly 
whether they are to be found in other similar places along the river, but no 
doubt this will be the case.”—-(E. S. Gourlay).

pe, a male, was collected at Wellington in June, 1895, by Hudson. 
This interesting species has been taken only in the Province of Wellington. 
e fly appears to be a characteristic winter and early-spring species.
