126 INSECUTOR INSCITIyE MENSTRUUS 



Ciii, the outer end of cell rst M^ and the fork of M^+o nar- 

 rowly seamed with brown ; pale brown clouds in cell Cui along 

 vein Cu; one or two spots in the basal half of cell M ; a small 

 brown cloud along vein ist A beyond midlength; veins dark 

 brown. Venation : Sc^ at the tip of Sc^ ; Rs long, angulated 

 at origin ; r at the tip of R^ and on Ro beyond midlength ; 

 -??2+3 a little shorter than the deflection of R^-\-5 ; r-tn about 

 one-half m; cell ist M^ long-rectangular, about equal to 

 vein Cii^ beyond it ; petiole of cell M^ a little more than one- 

 half the length of the cell ; basal deflection of Cu-^ at from two- 

 fifths to one-half the length of cell ist M^. 



Abdomen brown, dusted with light gray, especially the 

 sternites ; hypopygium light yellow. Male hypopygium with 

 the outer pleural appendage leg-shaped, the foot split into two 

 subequal, parallel points ; inner pleural appendage slender, 

 suddenly constricted at about three-fifths the length, the apex 

 cylindrical. 



Habitat. — New Zealand. 



Holotype, $ , Wellington, June, 1895 (G. V. Hudson). 



Gynoplistia sackeni is presumably the species mentioned by 

 Hutton (Trans. New Zealand Inst., vol. 32, p. 46, 1900) as a 

 variety of G. wakefieldi Westwood in which the flagellar pecti- 

 nations are unusually elongate ; the antennae are but 17 seg- 

 mented, however, and this latter may pertain to still another 

 species. It is clear that several species are confused under the 

 names of G. subfasciata Walker and G. zvakefiieldi Westwood, 

 the number and degree of pectination of the flagellar segments 

 being far too great to fall within the definitions of the above 

 species. 



Gynoplistia fimbriata, new species. 



Generally similar to G. sackeni; wings with the spot at origin 

 of Rs small ; wing-tip evenly darkened ; cell ist M., small, sub- 

 quadrate ; male hypopygium with the outer pleural appendage 

 profoundly branched, the inner branch very long and sinuous, 

 the tip acute. 



Male. — Length about 14 mm.; wing, 11.5 mm. 



Rostrum and palpi reddish brown. Antennae with the scapal
