Distribution. 



In this work 14 families of parasitic Hymenoptera are recognized in the Hawaiian 

 fauna, not a single one of which is pecuHar to the archipelago, but, on the contrary, 

 all have a wide geographical range, or at least have some representatives in all parts 

 of the world. 



These 14 families are represented by 128 species, distributed in 69 genera. Of 

 these genera only 1 1 are, apparently, endemic or peculiar to the Islands, viz., 

 Zacraniinii, Platytnischodes, Hypodiranchis, Neolclaps, Meso/eiaps, Solindenia, Pleu7-o- 

 nenropliion, A//iyreodoii, Banchogastra, Pycnophion and Ecphylopsis. 



Most of the other genera, except Ophcliims Haliday and Echthromo7'plia Holm- 

 gren, are represented in nearly all the known faunae. North and South America, 

 Europe, Africa, Asia and Australia, the two mentioned being more particularly confined 

 to the Australian and Asiatic faunae. 



Of the eleven genera mentioned as being apparently peculiar to the Islands, ten 

 are here described for the first time, and there is but little doubt in my own mind that 

 most of these will be found to have representatives in the Australasian fauna, from 

 whence it is evident, taking all things into consideration, that the Hawaiian fauna 

 was originally derived. 



Of the one hundred and twenty-eight species of parasitic Hymenoptera enu- 

 merated, eighty-seven are suppo.sed to be new and are here described for the first time, 

 so that, for the present, nothing can be said of their distribution. 



The known species, however, may be arranged into three categories, as follows : — 



(i) Of Asiatic or Australasian origin (5 species). 



Chalcis obscurala Walk., Tomocera californica How., (= Moratiila testaceiceps Cam. = M. testaceipes 

 D. T.), Evania appendigaster Linne and E. sericea Cam. 



(2) Of North American origin (7 species). 



Encyrtus fuscus How., Coccophagus lecanii Fitch, C. ochraceus How., Hemiteles tnelitaeae Ashm., 

 JJ. taiellus Sa)', H. variegatus Ashm., and Aphaereta tnuscae Ashm. 



(3) Of European origin (5 species). 



Spalaiigia hirta Hal., Tetrastichus hagenowi Ratzeb., Lissonota bellator Grav., Metacoelus femoralis 

 Fourc., and Bassus laetatorius Fabr.
