Haemaphysalis leporis-palustris. 



The life-history of this species has been studied experimentally by 

 Hunter and Hooker (1907, pp. 53-54), Hooker (1908, pp. 47-48), Rohr 

 (1909, pp. 100-110), Hunter and Bishopp (1911, pp. 228-229), Hooker, 

 Bishopp and Wood (1912, pp. 90-96), and Hadwen (1912, pp. 97-98). 

 Rohr's observations were made in Brazil, his " Haemaphysalis proooima " 

 havinof been found on wild rabbits and aofouti; Hadwen studied the 

 species in Canada, specimens having been collected in Manitoba and 

 British Columbia from Lepiis americanus; the remaining authors' 

 investigations were carried out in Dallas, Texas. In the following 

 pages I have sought to arrange the data supplied by these authors so 

 as to pre.sent them in a uniform mannoi'. A summary will be found at 

 the end of the section.
