ORTHOPTERA OF NOVA SCOTIA. — PIERS. 217 



must have been made between about 1820 and 1822, unless 

 he continued to reside here after he retired, which is i?.ot at 

 all likely. 



Francis Walker, F. L. S., when re-arranging the Orthop- 

 tera in the British Museum, studied and named Lieut. 

 Redman's Nova Scotian Orthoptera, and references to them, 

 twelve nominal species, was made in the former's "Catalogue 

 of the Dermaptera Saltatoria in the British Museum," 

 published in five parts at London, 1869 to 1870. This was 

 the first real contribution to our knowledge of such insects 

 in Nova Scotia; and Lieut. Redman is entitled to the credit 

 of being the first to collect and F. Walker of being the first 

 to make known our orthopteran fauna. In the "Canadian 

 Entomologist," London*, Ont., for February, 1872, vol. iv; 

 No. 2, pp. 29-31, Walker published a list of the "Hemiptera, 

 Heteroptera and Dermaptera (Orthoptera) of America to 

 the North of the United States," the list of Orthoptera being 

 on pages 30 and 31. In this list, which was merely selected 

 from his previous larger work, he gives twelve nominal 

 species of Orthoptera as occurring in Nova Scotia. Unfor- 

 tunately Walker's determinations were occasionally erroneous, 

 and so, owing to lack of confidence in his identifications and 

 nomenclature, but very little use has been made of his list 

 by recent American orthopterists. I have lately had Walker's 

 Nova Scotian specimens re-examined at the British Museum, 

 through the courtesy of Mr. B. M. A. Cummings of that 

 institution, and am thus able in the present paper to assign 

 for the first time, nearly all of his names to their proper 

 species. 



From the dates of Walker's lists until 1896 nothing 

 apparently appeared on the subject, except a mere note on 

 crickets at Windsor, N. S., by the present writer in the 

 Transactions of the N. S. Institute of Science, vol. viii, 

 p. 410, 1894. In August, 1895, I took up the study of these 

 insects and collected about Halifax, the result being a pre-
