HuTTON. — On tJio Cranc-flic$ of Neiu Zealand. 45- 



Genus Gynoplistia, Westwood (1835). 



Two submarginal cells ; five (rarely four) posterior cells ; 

 discal cell generally closed ; auxiliary vein reaching the costa 

 nearly opposite the base of the second submarginal cell. 

 First submarginal cell with a short petiole. Seventh longi- 

 tudinal vein distinctly sinuated. Wings and eyes glabrous. 

 Antennae 15- to 22-jointed ; most of the flagellar joints uni- 

 pectinate in both sexes, or serrate in the female. Tibige 

 spurred. Empodia distinct. Ungues smooth. Male forceps 

 like that of Livmophila, usually with one horny claw-shaped 

 appendage. Ovipositor long and pointed. 



Baron Osten-Sacken says that he has in his collection a 

 species of Gynoplistia from New Zealand, in which the wings 

 in both sexes are rudimentary.
