128 INSECUTOR INSClTlyE MENSTRUUS 



the apex acute ; the inner pleural appendage is constricted just 

 beyond midlength, the long, slender apex blackened at the tip. 



Habitat. — New Zealand. 



Holotype, $ , Greymouth (Helms), 



The type specimen bears the name here adopted, Gynoplistia 

 fimhriata, in Osten Sacken's writing. This species differs re- 

 markably from all other species of the genus known to the 

 writer in the deeply branched pleural appendages of the male 

 hypopygium. 



? Gynoplistia anthracina, new species. 



Coloration shiny black ; halteres brown, yellowish basally ; 

 wings dusky, with two broad, brown crossbands ; valves of the 

 ovipositor very long and slender. 



Female. — Length about 5.8 mm. ; wing, 6 mm. 



Rostrum and palpi black. Antennae with the first segment 

 black, the second segment slightly more reddish ; flagellum 

 broken. Head shiny black, the vertex between the eyes very 

 broad. 



Thorax shiny black. Halteres brown, the base of the stem 

 light yellow. Legs with the coxae black ; trochanters obscure 

 brown; remainder of the legs brown, the distal tarsal seg- 

 ments blackened. Wings with a slight dusky tinge, a spot at 

 the wing-base and two broad crossbands darker brown ; the 

 basal spot includes the bases of cells R and M ; the basal band 

 begins at the origin of Rs, extending from cell R and ist 7?^ 

 completely across the wing, ending in cell ist A; the outer 

 band lies at and just beyond the cord, completely traversing 

 the wing but slightly interrupted at cell ist M.^ which is slightly 

 of the ground-color; a small brown spot at the fork of M^-\-^; 

 veins dark brown. Venation : Sc^^ ending a short distance 

 before the fork of Rs, Sc^ at its tip; r very indistinct, not far 

 from the tip of i?i and on R^ at about one-third its length ; 

 Rs long; i?2+3 ^ little shorter than the deflection of i?4-|-5; 

 cell ist Mg small, subrectangular ; petiole of cell M^ more than 

 one-half the length of this cell ; m and the outer deflection of 

 M3 subequal ; basal deflection of Cmi beyond midlength of 

 cell 1st Af,.
