140 THE CANADIAN ENTOMOLOGIST. 



spruce swamp Podisma glacialis Canadensis, Mel. islandicus and Tetrix 

 granulatus were taken. 



At the foot of the mountain is an area of exposed rock, on which 

 Circotettix verruculatus, Camnula pellucida, Mel. a flam's, etc., were very 

 abundant. On the shady path up the mountain-side the only Orthopteran 

 met with was Mel. islandicus. which was not uncommon, but when we 

 reached the plateau referred to above, we found Chloealtis conspersa, C. 

 abdominalis and Sten. curtipennis, long- and short-winged forms of each ; 

 Mel. extremus and fasciatus, long-winged ; Circotettix verruculatus, 

 Camnula pellucida, Melanoplus atlanis and Tetrix acadicus. On the top 

 of the mountain both forms of Mel. fasciatus and of the two species of 

 Chloealtis were common, especially the long-winged form of the first-named 

 and that of C. abdominalis. A few females of Mel. altitudiuum and 

 many specimens of Mel. islandicus were also taken here. 



The country about Nipigon is rugged and picturesque, and wooded with 

 heavier timber than grows in the vicinity of Ft. William. We saw many large 

 white spruce, aspen, balsam poplar and canoe birch, and the vegetation 

 is, generally speaking, more luxuriant than in most parts of Northern 

 Ontario along the Canadian Pacific Railway. The Nipigon River above 

 the Railway Bridge flows swiftly between steep clay banks over a hundred 

 feet high, but a little below it there is a waterfall, after which it flows 

 placidly out to Lake Superior, the banks sloping gently to the water's edge, 

 which is bordered by low bushy pastures and damp woods. Here and 

 there open reedy marshes jut out into the river, and, not far below the fall, 

 there is an island consisting of a narrow strip of tamarack swamp sur- 

 rounded by a broad belt of open, partly submerged, marsh. This marsh 

 yielded the only species of Orthoptera, Mecostethus lineatus, not found at 

 Fort William, and was a wonderful locality for dragon-flies. 



The Orthoptera here are practically the same as those found at Fort 

 William. The most noticeable feature was the abundance of Mel. Brutieri, 

 which, with Camnula pellucida, was the common campestral species, 

 especially on dry soil. Mel. atlanis was quite local, and l\f. femur- 

 rubrum does not seem to have been observed at all. The same tendency 

 towards the development of macropterous or long-winged individuals in 

 species usually regarded as normally brachypterous or short-winged was 

 observed here, though apparently not in such a marked degree as upon 

 Mt. McKay.
