68 The Ottawa Naturalist. [Aug. -Sept. 



A FEW DAYS' WORK AND PLAY IN CANADA. 



By E. P. Van Duzee, Buffalo. N.Y 



In late June and early July, 1912, I had occasion to attend 

 a meeting of the American Library Association at Ottawa and 

 improved the opportunity to do a little collecting for Hemiptera 

 about the city and to meet a few of my entomological friends 

 there. At the Central Experimental Farm I found Dr. Hewitt, 

 Mr. Arthur Gibson and Mr. Germain Beaulieu and later had the 

 pleasure of taking two very profitable collecting trips with Mr. 

 Wm. Metcalfe. Our first trip was to Beaver Meadow, near 

 Hull, and on the next day he piloted me to a still better collecting 

 ground at Blueberry Point, near Aylmer. At Hull. I was par- 

 ticularly pleased to take a fine series of both sexes of my new 

 Criocoris canadensis. These were swept from grass on the 

 dryer meadows in considerable numbers. On a damper weedy 

 spot I found several examples of a Lygus allied to tenellus and 

 fasciatus which I believe to be still undescribed. It occurs 

 rarely at Buffalo, but I have seen numbers taken by Mr. Metcalfe 

 at Ottawa, and by Mr. Moore at Montreal. Other captures 

 interesting to me were Micro phylellus modestus Reut. in a good 

 series from grassy lowlands, Tropidosteptes canadensis Van D. 

 from an ash tree, and Athysanus chlamydatns described as a 

 Deltocephalus by Provancher and later as Thamnotettix infuscata 

 by Gillette and Baker. I was also pleased to obtain here a 

 typical specimen from its type locality of Gypona hullensis 

 Prov. which had previously been described as pectoralis by 

 Spangberg. Labops hesperius Uhler was common here as it is 

 everywhere in eastern Canada and northern New York and 

 New England. I secured a single specimen of Dichrooscytas 

 elegans Uhler from a cedar tree and Mr. Metcalfe pointed out to 

 me that the plants of a Senecio which was abundant there were 

 infested by a pretty fulvous Psyllid new to me. 



Our work next day was done under entirely different condi- 

 tions. The ground was very dry in the open woods at Blueberry 

 Point, but I took a few very interesting species, chief of which 

 was a series of four specimens of .4 mblytylns 6-guttatus Prov., an 

 elegant little velvety-black Capsid with olive head and three con- 

 spicuous white spots at the tip of each elytron .the anterior of which 

 was pale yellow in one of my examples. It was the first time I 

 had ever seen the species, which appears to be a Macrotylus and 

 is probably very local in its distribution. Here I also took 

 several specimens of Bank's recently described Pindus audax, 

 a species I have long known from western New York. 



I again visited this locality on July 3rd. working then on
