Described from 22 females, 19 males (type, allotype and 

 paratypes) all except one pair taken at various localities on 

 Oahu at all elevations (Swezey and Timberlake) ; one pair 

 (paratypes) taken on Pun Kapele, Kauai (Swezey). The 

 type and allotype were reared experimentally from Pseudo- 

 coccus lounsburyi Brain from a female captured on Kaumuo- 

 hona, Oahu (Timberlake). It has been reared experimentally 

 also from Pseudococcus longispinus (Targ.) and under natural 

 conditions from P. montanus Ehrhorn, P. galUcola Ehrhorn 

 and Ripersia palmarum Ehrhorn. It has been found asso- 

 ciated also with Trionymus insulans Ehrhorn on Eragrostis 

 variabilis. The oldest specimen seen is a female taken in Ho- 

 nolulu, Mar. 10, 1910 (Swezey).
