were allowed access to the females as they became available and additional 
males were introduced as required. Both sexes were fed about every 30-40 
days, usually when oviposition had temporarily ceased or when, from their 
general appearance, the females seemed to require food. The presence of the 
spermatophore in the genital aperture of the female can only be determined 
by handling the tick, and a few days after copulation it may become loosened 
and fall away. For this reason, the records of copulation are limited in number 
because it was considered advisable to disturb the females as little as possible 
between the oviposition periods. 
Experimental Records relating to females kept at different temperatures. 
It is necessary, at the present time, to condense experimental evidence 
for economy of space and therefore the records are presented synoptically 
below, Synopses I, II and III recording the life-histories of females main¬ 
tained at 22°, 30° and 37° C. respectively: 
Synopsis I. Females and progeny maintained at 22° C.
