borders of woods and streams, within a radius of twenty miles from this 

 city. I have marked with an asterisk such species as I have taken in 

 Ontario, mostly at Ridgeway ; but without doubt most of the species 

 found here could be found on the Canadian side of the river. 



* Brachytropis calcarata Fall., May to Aug. In damp situations. 



* Trigonotylus ruficornh Fall, June and July. Not common. 



* Mir is instabilis Uhl., M. affinis Reut., May to Aug. Common in dry 



fields. The dark fuscous form is rare here. Some beauti- 

 ful green examples taken at Ridgeway, Ont., May, 1886. 



* Leptopterna dolobrata Linn., May to Aug. In dry fields. Probably our 



most abundant Hemipter. It attains full development 

 about June 1st, and frequently appears in immense swarms 

 in favorable localities. 



* Trachelomiris oculatus Reut., June to Aug. Rare. 



* Trachelomiris Meilleurii Pro v., Nab idea coracina Uhl., June to Aug. 



Common in open rich fields.  



Resthenia iiisitiva Say. One example of the form with black scutellum, 

 taken July 4th, 1879. 



Lopidea media Say, July, common. A few examples of the yellow vari- 

 ety, named C. robinice by Mr. Uhler, taken in July, 1885. 



Phytocoris eximus Reut, July and Aug. 



Phytocoris tibialis Reut., July and Aug. A handsome species, occurring 

 in considerable numbers among rank weeds, near water. 



Phytocoris pallidicornis Reut. One example taken at Colden, N. Y., 

 July, 1885. 



Phytocoris scriipens Say, June and July, Very variable. The most 

 abundant form here is the pale or ochreous variety, gener- 

 ally taken on the Staphylea. One example of the typical 

 form described by Say was presented to me by Mr. Ph. 

 Fischer, who took it near this city, and with it another vari- 

 ety which may prove to be a distinct species • it has the 

 pronotum black, with the narrow edge, and three longitudi- 

 nal vittEe ochreous, and differs slightly in other respects from 

 the ordinary forms of scrupens. 



Phytocoris colon Say. Three examples taken in Aug., 1886. This species 

 was described by Mr. Say in 1 83 1 , but seems to have been 

 overlooked by later Entomologists until 1884, when M.
