Psyllidae of New Zealand — Tuthill 103 
Fig. 13. Trioza gourlayi n. sp. a, Lateral aspect of female cauda; b, lateral aspect of male cauda. 
cember 7, 1950, E. S. Gourlay, beaten from 
Discaria toumatou in company with T. discariae. 
Although I collected in the same area 6 weeks 
later, I was unable to find any of this species. 
HOST PLANT: Discarta toumatou Raoul 
(probable) . 
This species is quite close to T. bifida. The 
genitalia of the female are quite different, 
however, and the male forceps, although 
similar, are more slender, curved, and the 
apical notch is more oblique. 
It is with much pleasure that I name this 
species for the collector E. S. Gourlay.
