has tliougliT it wise To redeseribe the species with a review of 

 the host records. In accordance with a recent paper by Ciish- 

 man and Eohwer^-' the species must be placed in the genus 

 EplilaUes Sehrank. A species that is best referred to Itoplectis 

 is also brought forward as new.

There seems to be considerable confusion in regard to this 

 species probably arising from the fact that Ashmead failed to 

 descril)e the female correctly. That the hind legs are entirely 

 red in the female was not In-ought out, Ashmead merely adding 

 to Cameron's description of the male, which w^as copied ver 

 batini with one slight omission, the length, and the statement 

 that the ovipositor is less than one-half the abdomen. This 

 may account for Perkins believing that there is a second "com- 

 monplace Pimpla'' in the Islandst, a record which I cannot ac- 

 cept as all the local collections sliow but this one species and 

 the new Itoplectis described below. Morley has synonyuiized 

 ]iaii''aiien.sis with Ephialtes turionellae (Linne) after exauiin- 

 ing (\imeron's type male. AVhile there seeuis to be no reason 

 to dispute Morley's decision that the male of this species is 

 quite typical of turianellae, this in itself even if entirely true 

 is not sufficient grounds for synonymizing the species, since 

 two species as in the present case may be quite or nearly iden- 

 tical in one sex and as clearly distinct in the other. 



Ilawaiiensis is probal)ly an iuimigrant froui some part of 

 America and Perkins considered that he had seen the same
