The family is represented in the endemic fauna by s}»ccies 

 belonging" in at least five genera, of which Anar/yriis Howard 

 has about a dozen to fifteen species falling in a rather distinct 

 group almost worthy of generic distinction. Xan(JtoPnri/)ius 

 Ashmead has three or possibly more species, none of them bav- 

 ins: been hithertofore descril)cd and onlv one recorded under 

 the name of Ectroma species. Echthrogonatopus Perkins has 

 at least three species, E. hairaiiensis Perkins, E. moloJx-aiensis 

 (Ashmead) and one undascribed. The two remaiiiing genera 

 are represented by one or two species each, and are of unusual 

 interest because of the structural peculiarities in the male sex. 

 The first of these interesting and probably wholly endemic 

 genera is CueJopencyrtus Timberlake with two species parasitic 

 in the larvae of Odynerus. one of which as already stated Mr. 

 Swezey has noted and figured under the name of Agenia.'ipis 

 species. The other genus and species is Nesencyrtii.-; kdaJaa 

 (Ashmead), of which Dr. Williams has reared a large series 

 from the larvae of Nesoprosopis piihescens Perkins taken from 

 an old rotten log near the Volcano House at Kilauea, Hawaii, 

 in February, 1U18. 



The innnigrant and introduced species belong in about 

 twenty genera and have come mostly from the Oriental and 

 Australian regions apparently, although at least three wei-e 

 introduced from Xorth America, these being /I('lr(/()ii(if(>j>i(.s- 

 pseurlopJiaiics Perkins, Saiv)iotum americaiiiiDt Perkins and 

 Aphidcnryrtu.s schizoneurae (Ashmead). Cameron's species 

 BothrieticyrI i(s iiisularis is of uncertain oi-igin although judg- 

 ing by the descripttion it seems to be an ally of Bofhricnci/rfiis 

 planifonnift (Howard) of California, wliicb is the type of 

 this new g-enus. 



"These four species are Botltriciicyrtiis insulnris (Cameron). Hoiitalo- 

 fyltis flaiiiiiiius (Dalinan). Microtcrys flaviis (Howard) an J Coiiiffcriclla 

 bifasciata Howard.
