dark brown. Venation- r at tip of Ri and at two-thirds Ro; cell Mi only 

 a little longer than its petiole; basal deflection of Cui at midlength of 

 cell 1st Mo. 



Abdomen uniformly reddish brown; a very faint and indistinct, 

 capillary, brown, median line, broadly interrupted at the posterior 

 margin of the segments. Male hypopygium reddish brown; outer 

 pleural appendage broad at base, the apex dilated into a dark brown 

 paddle-like blade; inner pleural appendage with the apical half consid- 

 erably narrower than the basal half and provided with numerous tiny 

 seta?. Gonapophyses complex, each side with three spines; the most 

 cephalic of these is the smallest and very slender; the second spine 

 is a powerful horn diiected proximad, lying immediately caudad of the 

 basal spine; besides these there is an elongate spine on either side of 

 the penis-guard, directed caudad, gradually narrowed to the tip. 

 Penis-guard very small and weak. 



Hab. New Zealand (South Island). Holotype, cf , Otatara, 

 Otago, November 25, 1906 {A. Philpott). 



Gynoplistia spinigera, sp. n. 



General coloration light gray; antennas of male 17-seg- 

 mented; wings sybhyaline, the pattern almost obliterated; 

 stigma distinct; abdomen light brown with a subterminal 

 black ring; penis-guard with conspicuous serrations before 

 the apex. Male. — Length 11 mm.; wing 10 mm. 



Rostrum light gray; palpi broken. Antennae brown, the first 

 scapal segment slightly dusted with gray; basal flagellar segment paler 

 on basal half; antennae 17-segmented, the formula being 2+2+9+4, 

 the longest flabellation about four times the segment ; eleventh flagellar 

 segment with only a tiny protuberance and may not be considered pec- 

 tinate by some, in which case the formula would be 2+2+8+5. Head 

 light gray with a U-shaped mark on the vertex, the arms becoming 

 evanescent behind. 



Pronotum light gray. Mesonotal prsscutum gray with four rust- 

 brown stripes, the intermediate pair becoming obsolete behind, being

 tellum destroyed by pin; postnotum gray. Pleura pale reddish brown, 

 dusted with gray. Halteres broken. Legs with the coxae pale reddish 

 brown, dusted with gray; trochanters yellow; femora and tibiae brown, 

 pale ring on femora almost obliterated; tarsi dark brown. Wings sub- 

 hyaline, the pattern very reduced; cells C and Sc very pale brown; 

 stigma conspicuous dark brown ; a small brown cloud at basal deflection 

 of i?4+5; very indistinct brown seams at origin of Rs; along the cord; 

 a small, faint cloud at outer end of vein Cu^ and another on vein 1st A 

 immediately above the end of vein 2nd A; wing-tip clear; veins brown.
