IRISH ICHNEUMONIDAE AND BRACONIDAE IN 



1920. 



BY REV. W. F. JOHNSON, M.A., F.E.S., M.R.I. A. 



The cold wet summer of 1920 was no better for Ichneumon 

 Flies than for other insects, and, as a consequence, my list 

 is not as long as it might have been. I was very unfortunate 

 in the weather while at Portnoo, and my captures were 

 but few. In spite of all drawbacks, however, I have three 

 species to bring forward as additions to the Britannic List, 

 which are as follows : — 



1. MiCROCRYPTUs FEMORALis Thoms. — Poyntzpass, in 



July, at Hog Weed in my field. Dr. A. Roman 

 who kindly determined this and other species 

 for me, tells me he has since seen it from England. 



2. Glypta Schneideri Krieger. — Portnoo, in June, 



on cliff. Dr. Roman says it is " probably " 

 this species, which was originally described from 

 the island of Borkum in the North Sea and has 

 been taken in Sweden. 



3. Mesoleius fraternus Holmgren. — Poyntzpass, in 



my fields flying along the hedgerow. This 

 species is near M. fallax Hlgr. but has no areolet 

 (vide Holmgren " Monographia Tryphonidum 

 Sueciae," p. 173). 



Sir C. Langham very kindly sent me a piece of wood 

 bored by Sirex gigas in hopes that either Sirex or Rhyssa 

 persuasoria might emerge ; Rhyssa alone emerged. A male 

 was the first to appear on May 3rd ; this was followed by 

 a female on May 6th and a second on May 9th. I 

 unfortunately killed the male and first female, but I kept 

 the second female alive and she lived till May 25th, i.e., 

 16 days. 



At Lenaderg on June 5th Mr. Davies and I spent a long 

 time watching Rhyssa at work, but we did not obtain any 

 additional observations to those already published.^
