Dilophus segnis Hutton, 1901, New Zealand 
Inst., Trans. 34: 194. 
This species is related to P. insolita (Hutton) 
but is distinguished by the arrangement of 
the spines on the front tibiae (Fig. 6b ) ; by the 
small, poorly developed apical spurs of the 
front tibiae (Fig. 6a ) ; and by having the hind 
metatarsi of the males more strongly swollen, 
broader than the apices of the tibiae. The 
ninth tergum is twice as wide as long, and 
the hind margin is very slightly concave (Fig. 
6c). The ninth sternum and the claspers are 
shaped as in P. insolita (Fig. 4c). For further 
descriptions and figures of this species see 
Hardy, 1951 (Hawaii. Ent. Soc., Proc. 14: 
272-273). 
LENGTH: Body, 4. 5-5.0 mm.; wings, 4.0- 
4.2 mm. 
TYPE LOCALITY: Christchurch, New Zea- 
land. 
The type is in the Canterbury Museum, 
Christchurch. 
I have previously recorded this species from 
several localities in New Zealand. Two female 
specimens have recently been seen which ap- 
pear to be this species; they were from Blen- 
heim, Nov. 15, 1942 (D. Spiller) and Titi- 
rangi, Auckland, Oct. 2, 1949 (E. Bray). 
Philia tuthilli n. sp. 
Fig. la-f 
This remarkable species is readily differen- 
tiated from any known member of the genus 
Philia by its incomplete wing venation. This 
is the only species which I have seen from 
the entire world which lacks the m crossvein 
(posterior crossvein) and which has the bases 
of veins Mi-j -2 and Mi evanescent (Fig. id). 
This is also one of the smallest species of 
Philia which has been recorded, and the shape 
of the head (Fig. la) is unique for this genus. 
MALE: Tiny, chiefly shining black species 
with a faint, reddish tinge in the ground color 
of the pleura, humeral ridges, scutellum, and 
legs. Pile all black. Head: The upper portion 
of each compound eye is brownish red and 
is densely covered with short pile; the lower 
part of each eye is black. The front margins 
of the compound eyes are produced beyond 
the bases of the antennae and completely ob-
