WILLIAM H. EDWARDS. 

 We regret to record the death, at the ripe old age of eighty-seven years, 

 of this eminent entomologist, which took place at Coalburgh, West 

 Virginia, on the 4th of April. He was an honorary member of the 

 Entomological Society of Ontario, and contributed a large number of 

 papers to this magazine during a long series of years. His son, the Hon. 

 William Seymour Edwards, of Charleston, W. Va., has promised to 

 furnish us with a memoir of his father, which we hope to be able to 

 publish in the July number. 



ON THE ORTHOPTER.A OF NORTHERN ONTARIO. 



BY E. M. WALKER, TORONTO. 



(Continued from p. 144) 



1. Nomotetti.x boreaiis, n. sp. (PI. 7, fig. 1, ia.) 



Closely allied to N. cristatus Harr., from which it differs as follows : 

 Median carina of vertex somewhat less prominent, projecting a shorter 

 distance in advance of the front margin ; vertex not projecting quite so far 

 in front of the eyes, the angular excavation beneath it, seen in profile, 

 shallower, the frontal costa gently sinuate. Antenna? (broken off in one 

 specimen) 12 jointed, about one-fourth shorter than in cristatus. Median 

 carina of pronotum less regularly arched, highest opposite the fore coxa 3 , 

 the height thence diminishing somewhat more rapidly and irregularly than 

 in cristatus. In the type specimen the midcarina at its highest point is 

 somewhat higher, in the other, which I have figured, about as high as in 

 typical cristatus. Hind femora somewhat narrower and less ampliate at 

 base than in the latter. 



Length of body, 8.5 mm.; pronotum, 8 mm.; hind femur, 5-5.6 mm. 



Two females, shore of Diamond Lake, Temagami District, Sept. 7, 

 1908. 



Both specimens are of a dark rust-brown colour, the dorsum of the 

 pronotum darker, with a grayish tinge and with two pairs of black spots, 

 the posterior larger and somewhat triangular. A pale yellowish specimen 

 was also seen, but not captured.
