174 THE CANADIAN ENTOMOLOGIST. 



The specimen figured was examined by Prof. Morse, who wrote to 

 me that it was new, perhaps a northern variety of cristatus. I am inclined 

 to think that this is its proper status, but in any case, it seems worthy of 

 a name. 



The shore of Diamond Lake, where these specimens were taken, is a 

 broad sandy beach about 100 yards in length, and the lake for some 

 distance out from the shore very shallow and reedy. The beach is 

 bounded behind by a narrow irregular ridge a few feet in height, which 

 has apparently been pushed up by the ice in winter. This ridge supports 

 a growth of Banksian pine, some of them quite large and spreading, with a 

 very luxuriant undergrowth of Canada blueberries and other shrubs in less 

 abundance, Lack of the ridge is a large open sphagnum bog with a dense 

 cover of Ericaceous shrubs, such as Dwarf Cassandra, Andromeda, 

 Kill mi a angustifolia and blueberry bushes. Between the ridge and the 

 zone of heath shrubs is a strip of nearly dry sandy soil a few feet wide, 

 with scattered blueberry bushes, etc. It was here that these Tettigians, 

 along with one example of Tetrix acad/'cus, were found. 



2. Tetrix granulatus Kirby. 



Fort William, Aug. 27, 1907, 1 £ , 1 9 ) Temagami, portage between 

 Lakes Obabika and Temagami, Sept. 11, 1908, 1 <?• 



3. Tetrix B runner i Bol. 



Near Temagami Fdlls, Sept. 2, 1908, 1 6* , macropterous, from a 

 small opening on a portage through a forest of mixed white pine, spruce, 

 balsam, canoe birch, etc. A very few Melanoplus islandicus and one 

 M. femur rubrum were the only other Orthoptera found here. 



This specimen measures as follows : Length of body, 10 mm.; 

 pronotum, 12.5 mm; hind femur, 6 mm. It is pale yellowish-brown 

 above, the pronotum marked with two large triangular velvet-black spots, 

 followed by a pair of elongate black streaks. 



This species was reported by the writer from Algonquin Park, some- 

 what doubtfully as T. acadicus (36th Ann. Rep. Ent. Soc. Out., 1905, p. 

 66). The two Algonquin Park specimens, both males, are similar in size 

 to the Temagami one, and one of them is nearly the same in colour 

 pattern, but in both the pronotal process is much shorter, extending in the 

 single specimen now in the writer's collection, less than 1 mm. beyond 

 the tips of the hind femora, the wings projecting very slightly farther. In 

 the Temagami specimen the pronotal process reaches 4 mm. beyond the 

 hind femora, and the wings .75 mm. farther.
