FIVE SPECIES OF ICHNEUMONIDAE NEW TO 

 THE BRITANNIC LIST. 



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



Among some Ichneumonidae sent by me to Dr. A. Roman, 

 the eminent Swedish hymenopterist, were the following 

 five species which do not appear to have been previously 

 recorded from the British Isles, viz. : — 



Ichneumon amphiholus, Kriech. 



Phygadetwn oppositus, Thomson. 



Hemiteles fumipennis, Thomson. 



Cryptus titubator, Thunberg. 



Hypamblys buccatus, Holmgren. 



Ichneumon amphibolus, two females, one taken at Portnoo, 

 Co. Donegal, among grass and vetches in a small meadow 

 on the cliff, the other at Poyntzpass in one of my fields 

 among herbage. In each case the insect was taken in 

 September, and curiously enough on the same day, viz., 

 17th, though at a year's interval, the Portnoo specimen 

 being taken in 1918, the Poyntzpass one in 1919. It is 

 near to /. stigmatoriiis Zett, but differs according to Dr. 

 Roman ^ in the following points — the antennae are stouter, 

 with the basal half not rufous, the areola is subelongate, 

 the anterior femora always, and the 3rd segment of the 

 abdomen very often black. In my specimens the 3rd 

 segment is black. 



Phygadeuon oppositus, a female taken at Portnoo in 

 September among sallows on the roadside. It belongs to 

 the fumator group. 



Hemiteles fumipennis, a female taken at Portnoo at the 

 same time and place as /. amphibolus. I have not got 

 Thomson's descriptions of these two species, so I am unable 

 to indicate the points of distinction from their allies. 



Cryptus titubator, a male taken at Portnoo in June among 

 sallows on the roadside. Dr. Roman tells me that it is 

 a small race of C. albatorius Vill. and was called infumatus 

 by Thomson.
