CHEYSIS. 469 



on the window, and after some preliminary inspection of her nest, 

 and hauling and dragging of the caterpillar, crammed it into the 

 cell. She took quite a long time over it, with sometimes her head 

 and thorax inside the cell and sometimes her abdomen. All this 

 time the cuckoo-wasp remained perfectly still, watching. As 

 soon, however, as the Eumenes had flown away, the Chrysis 

 again approached the nest, slowly, and apparently with great 

 caution. She walked all round it, then up the side, and peeped 

 in, withdrew her head, seemed to give a final good look all round, 

 and popped in. She could not have been more than a few seconds 

 inside, when a loud buzz announced the return of the rightful 

 owner of the nest. I had barely time to glance at the Eumenes, 

 which alighted, as before, on the window, when my attention was 

 attracted by the darting-out of the cell of the burglarious cuckoo- 

 wasp. The Eumenes saw it, too, and with what sounded very like 

 an angry buzz, dashed after it in pursuit, overtook it, and then 

 the two dropped to the ground. I ran out, but I had to go round 

 by a verandah too high to jump, to the steps, and by the time I 

 arrived on the ground the fight was over, and the Eumenes had 

 disappeared. The Chrysis, however, lay on the ground, crippled 

 and crawling painfully, with all its wings torn off close to the 

 roots. I have the specimen and one torn fore wing, which was 

 all I could find, in my collection still. Returning to the nest, 

 I sat and worked at a table near it for more than an hour, and 

 inspected it at intervals through that day, but the Eumenes never 

 returned, and next morning the cell was still open and unsealed. 

 I tried to take it off with care, but it broke to pieces. Inside was 

 one green caterpillar and two semitransparent white eggs, one 

 much smaller than the other ; of these eggs, the larger one was 

 stuck against the wall of the cell, the other deposited on the 

 caterpillar. I may mention that the caterpillar was quite dead."
