LIST 2 
Chiggers for which only fragmentary information is available. 
All from wild-caught rats unless otherwise indicated. 
42. Euschongastia audyi (Womersley) 
One for 2 days, three for 8 days when rat died. 
43. E. indica (Hirst) 
The records for this chigger are very difficult to interpret. Evidently it feeds for a very 
long time, longer than for any other species recorded, and too long for host rats to be kept in 
small cages in the present style. Records from wild-caught and 2-day rats indicate a minimum 
feeding time of at least 12 days and a maximum of possibly some months, but of forty-nine 
chiggers from seven i-day rats only four fed for more than 15 days, giving a mean time of 9 days. 
Such an inconsistency may indicate different biological races, or a feeding time which varies 
with host behaviour, and is being further investigated.
