Ecological and Behavior Notes 41 



by the doorway and entered their nest through a rent in 

 the sack. The colony was very strong — at least in the 

 estimation of the small son who complacently sat down 

 upon the sack. Bees of this species were seen visiting 

 the few remaining flower heads of sweet clover on August 

 24, 1916. 



Apis mellifera Jjinii. A white flower spider, Mesumena 

 vatea Clerck. [C. R. Shoemaker] was inconspicuously at 

 rest among the flower-heads where it was sucking the 

 life-blood of a honey-bee. I could not see the spider at 

 first, but was attracted to the motionless honeybee among 

 hundreds of active ones, and soon discovered the reason 

 for the condition. 



ANTS 



Crematogaster lineolata Say. [W. M. Wheeler]. In 

 the fall, solitary queens of this species are found in tun- 

 nels made by the Ceratina bee and Hypocrahro wasp in 

 sumac and crimson rambler stems. Often the queen 

 makes for herself a little crypt, and uses bits of pith from 

 the sides to plug up the opening. A dead queen was 

 found in such a stem on March 9, 1919 ; it had probably 

 died of the cold despite the fact that she had made for 

 herself a cozy little room by building a partition or plug 

 of tightly packed pith. During the summer the colonies 

 become quite large. One such colony was taken in the 

 stem of a crimson rambler rose on August 14, 1917. 



Camponotus herculeanus L. subsp. pennsylv aniens 

 De G. [M. W. Wheeler]. Several females of this species 

 were flying about the lights in the house in the evening 

 of June 18, 1918. Some were smaller than others, and were 

 probably males. One female flew under the lampshade 

 containing a sixty-watt lamp, came out fluttering the 

 wings and fell dead. On June 28, 1918, a worker of this 

 species was taken from the jaws of a cincindcla beetle. 



Eciton schmitti Emery. [W. M.. Wheeler]. A long file 

 of workers of these driver ants was seen at Wickes on
