I may draw attention to the possibility that N. alba Oliv., and 

 N. pusilla are identical. The only difference is the black lateral 

 bands by N. pusilla. As far as I know N. alba is not represented 

 in collections, and has not been seen by anybody except Olivier. 

 It was very common about the end of May in Bagdad. 



I cannot give anything more on the classification of the other 

 species, as a number of them are not before me ; it would be neces- 

 sary to examine both sexes to arrive at a satisfactory conclusion. 

 Therefore I give only a list of those species, which I believe to be 

 genuine.

THE BOW AND ARROW UNKNOWN TO PALAEOLITHIC 



MAN. 



BY HENRY W. HAYNES. 



My attention has been called to some remarks of Dr. A. A. 

 Julien at a meeting of the New York Academy of Sciences, April 

 7, 1884, printed in their Proceedings, hi, p. 81, in which he takes 

 exception to a statement contained in an article by me in the 

 American Antiquarian, for the preceding month (vi, p. 137). 

 In criticising President Warren, of the Boston University, for 

 misuse of language in calling the builders of the pyramids of 

 Egypt " palaeolithic Africans," I had insisted that the word " pal- 

 aeolithic" is a technical term of science, as strictly limited in 

 its signification as are the words palaeography or palaeontology. 

 As defined in Ogilvie's Imperial Dictionary, it means " belonging
