the broom. When they left the mines the larvae appeared to me to be 

 quite full fed. 



The eggs were laid in September, 1907, and it was on October 15th 

 that I found the first larva in the fourth instar. This was evidently a 

 very forward individual. The first vacated mine was found in the 

 open on December 9th. Most of my larvae came out of the mines 

 between December 6th and Januarj;- 4th. On the other hand, I found 

 four larvfe in the field, still in their mines, on March 23rd, 1908. I 

 have good reason to believe that the common broom is not the only 

 food-plant, but that the larva may also feed on those brooms with 

 rounded twigs, usually called Spanish brooms.

 Note. — Heavy thunderstorm of extreme violence for one hour and 

 twenty minutes, during which time the birds did not feed. After it 

 was over, as I was drenched and trees and heath fired about 80 to 100 

 yards from my tent by the blinding flashes, I left ofi' for the day. I 

 found I was really too far off to see well. The first observation was 

 made whilst I was outside my tent arranging decorations, and the ? 

 came into a tree within a few feet of me and gave me a good view.
