 FAUNA OTTAWAENSIS. 



Hemiptera. 



By \V. Hague Harrington, F. R.S.C. 



Since the publication, in June 1892, of the list of Ottawa Hemiptera 

 (Ottawa Naturalist, Vol. VI, page 25), the following additional species 

 have been collected, and have been kindly identified by Mr. E. P. Van 

 Duzee. Unless otherwise stated, only single specimens have been 

 observed. 



HETEROPTERA. 



Corimelsena nitiduloides, Wolff. April 15th. 



Euchistus ictericus, Linn. June 3rd 1893, Mer Bleue. May 25th 

 and June 10th, 1894, Hull. 



Phytocoris tibialis, Reut. Apparently common. July. 



Neurocolpus nubilus, Say. July 29th. 



Lygus pabulinus, Linn. July. 



Diplodus socius, Ulikr. July 30th. On Solidago, near Hull 

 This species is recorded from the Western States, and Mr. Van Duzee 

 expresses his surprise at its occurrence at Ottawa. He asks " did it not 

 come from British Columbia ? " As it was captured not many hundred 

 yards from the main line of the famous C.P.R , it may possibly have 

 stolen a ride across the continent upon some train. 



Limnotrechus marginatus, Say. Sept 3rd. Roth sexes (and 

 young apparently of same species) abundant in the canal. Probably 

 the common species of all our waters. 



Rhagovelia obesa, Uhler. Nov. 3rd. Both sexes abundant in 

 Rideau River, above the railway bridge, near Hog's Back, in the small 

 pools of the rapids. 



HOMOPTERA. 



Agallia sanguinolenta, Prov. June 26th. 



Parabolocratus viridis, Ullwr. This insect was erroneously given 

 in the list as Gypona quebecensis, Prov., which is a synonym of G. 

 striata, Burm.
