of this rare species. In May 1910, at Box Hill, he found in a 

 hole in a flint a small colony comprising a certain number of 

 workers, a queen, eggs, and young larvie. Some days later in 

 the same locality he found a second but smaller colony, also 

 in a hollow flint. From the appearance of these colonies it is 

 exceedingly probable that they had been actually founded 

 by the females in these situations. These two colonies were 

 placed together in a plaster nest, but the larger one killed the 

 queen and workers of the smaller and appropriated their brood. 

 The nest is now in excellent condition, and has reared about a 

 hundred workers during the two years, but no females have 

 been produced, and only one male, on July 5th, 1911. The 

 ants seem almost entirely carnivorous. 



Workers of this species also have been often found in nests 

 of other ants by Donisthorpe. 



The species of the genus Cremastogaster are undoubtedly 

 self-founding. Emery found a deälated female of C. scutellaris 

 (in a hole in a tree) on October nth, 1903. He placed her in a 

 Janet nest, where she passed the winter without laying eggs. 

 On April i6th, 1904, there were twelve eggs, but on May 2nd 

 only ten. 



On June nth some of these eggs had become small larvœ ; 

 on the 2 ist two larvae had pupated, and there were some 

 eggs and one larva. Some of the eggs were used to feed the 

 larva. The first worker hatched on July 9th ; the second three 

 days later, but was a cripple. He now gave the ants some 

 honey, which was the first food they had taken. On August 6th 

 there were six pupae, one of which hatched on the 12th and 

 another on the 14th. Thus the colony was definitely founded. 

 PouLTON and Hamm witnessed a marriage-flight of C. scutellaris 

 (near Porto Pi, Palma, Majorca), in July 1901, and picked up 

 three deälated females. These were kept by Hamm in Oxford 

 in a small box without food or water. One of the females kept 

 aloof from the other two, who were always seen together, and 

 after a month or two the solitary female was found to have a 

 leg missing, and shortly afterwards she was dead. The two 

 survivors in due course laid eggs and brought up a small brood 

 of larvae, W'hich produced small workers the following year, 1902. 



Mr. Cook records a case of C. lineolata adopting a new queen.
