NEW GENESA A\D SPECIES OF J.I'STEALIAX THTSANOPTESA—UOOD. 149 



Total length of antenna, 0-974 mm. 



Described from three males taken by sweeping in forest at Nelson, N.Q., 

 February 16, 1911, June 13, 1912, and August 12, 1912, by Mr. A. A. Girault. 



A large and eonspiouous species, very different from the Bornean A. simplex, 

 and one which I take [ileasure in naming for Mr. Alexandre A. GiiauJt. 



Mr. Bagnall, \\ho described the genus Adiaphorothrips, has kindly examined one 

 of the types of ijiraidti and concurs in my assignment of the species to this genus. 

 The shorter tube, the position of the posterior ocelh, and the different proportionate 

 lengths of the third, fointh, and fifth auteniial segments make (jira)ilti easily recog- 

 nisable.
