EphcJnis liicnin ph'his { Provaneher). Oui' E/ihrdnis was 

 determined hy ^fr. (Jahan as Provanehcr's species. It has 

 heen reai'ed h_v the writer from a otccii species of Macrosi- 

 pli 11)11 on I'ose hushes at ITonohdn, and Mr. Swezey ohtained it 

 from the same host at Waihdcn, ^Mani, on June 18, 1910. 

 This s])ecies seems to have lieen first collected hv Dr. Lyon 

 on April 18, 1914, on the same host. 



Didcrelus clicnupudldphtdis (Ashnu>ad). Our species of 

 Diaereius is not rapac (Cnrtis), hnt Ashmead's species which 

 is chiefly distinguished by having- lo antennal joints in the 

 female and 10 in the nude, instead of 14 and 17 respectively, 

 and by a slight difference in coloration and scnlptnre. This 

 species has heen reared from Aphis hmssicac Linnaeus, and 

 JihopalosipJiuDt persicac (Snlzer) from several localities near 

 llonolnln. 



Diiwcampus terminatus (Xees). The writer has examined 

 specimens of this species from Hnng'ary ; Barcelona, Spain ; 

 Palroa, Xew Zealand; Fiji; Okitsn, Ja})an ; and from many 

 localities in the United States from ]\Lissaehnsetts and Virginia 

 to (^ilifornia and Washington. Perkins also rec(n-(ls it from

 althongh there is a slight variation in color this seems to be 

 independent of its geographic distribution. In the Hawaiian 

 Islands it was probably introduced with Olla (ihdominaJh 

 (Say) from North America, but it now nsnally attacks Coel-
