Longeviti/ of unfed kmae, nymplis and adults. 
(Lot 1305.) 
Lai~vae which ejnerged on 10. iv. 1912 were very lively on 21. iii. 1913, Le. after 345 clays. 
(12 lots of larvae which emerged at about the same time were ecjually lively after 
256 days and upwards ; they were successfully raised. They were maintained at 
room temperature! in tightly corked tubes.) 
Nymphs which abandoned the host in an unfed state on 7.xii. 1912 were very active after 
52 days. Similar nymphs which dropped off the host on 31. x. 1912 were fairly active 
after 89 days (28. i. 13); they died after 141 days. (At room temperature! in tightly 
corked tubes.) 
Adults which emerged 24. i. 1912 were lively after 369 days and some were still living after 
421 days (21. in. 13). (At room temperature! on earth in jars.) 
Summary. 
The foregoing raising experiments show that Hyalomma aegyptium 
usually requires three hosts upon which to feed in its larval, nymphal 
and adult stages. When larvae are placed on hedgehogs, however, 
about half of them drop off as gorged nymphs, so that upon this host.
