Conclusions from the foregoing protocol regarding the time H. cin- 

 nabarina var. punctata remains upon the host: 



Larvae placed upon a hedgehog in June-August, the host being 

 maintained at 16-17° C, remain 3-11 days upon the host, the majority 

 dropping off gorged after 4-7 days. In November-December, the 

 temperature being 10-12° C, they remain upon the host 7-21 days, 

 the majority dropping off gorged after 13-21 days. When placed on 

 rabbits and sheep in June, at 17° C. they drop off gorged after 6-15 

 days. 



Nyniplis, placed on hedgehogs at 20° C, all dropped off by day 12; 

 at 11-13° C. they dropped off after 7-29 days; at 8° C. after 32-33 

 days. 



Adults {%) remained upon the hedgehog at 12° C. for 14-18 days. 



Note: — Stockman (1911), who raised H. cinnaharina var. punctata 

 on cattle and sheep, records that. 



The time required by H. cinnabarina var. punctata 

 for metamorphosis. 



In the protocols dealing with this section I include those of Stockman with my own
