[Note : — I had to leave at this point and the next day when I 

 hoped to continue I found the young had quitted. This day was dull 

 and thundery and very few insects were moving. I saw no Lepi- 

 doptera moving except those I kicked up. 21 visits are recorded. On 

 twenty occasions food was brought; I failed to identify it eleven 

 times. The other nine times it was always insects and five times out 

 of the nine it was Lepidoptera or partly Lepidoptera, which were I 

 feel certain taken at rest. I particularly draw attention to the number 

 brought, viz., thirteen in five visits. Also to the time taken. The $ 

 took a quarter of an hour to get three Cram bites. The 3- was about 

 ten minutes getting four. The 5 ten minutes getting one Epiblema 

 and three Crmuhites whilst the $ was exactly three minutes getting 

 the C. pamphibts.] 



[Note : — With regard to times my brother and I have had occasions 

 to work at one nest with two hiding tents, each independently noting 

 his own times, and we were unable to check as I cannot hear him 

 speak (unless he shouts very loudly) through the two thicknesses of 

 tent material, we have been surprised after to find that we rarely vary 

 a second on times if we synchronize our watches at the start as we 

 usually do, so I think it may be assumed that the times recorded above 

 are correct to within a second or two.]
