 Iloniatito, Mo. Tlio day was dull and gloomy; despite 

 the fact that wasps of tliis ,«>:enus are supposed to he sun- 

 lovinu^ creatures, more than a dozen of these were seen 

 on tlie sandy patches alon.ir Joachim creek, apparently 

 forairiiiff, walkincf nervously ahout and explorin*:: all 

 small holes anil crevices. They were also out here on

Arachnophociotnis frrnn/incKs Say. [S. A. Kohwcr]. 

 Two specinuMis of this Pomjiilid wasp were taken at 

 A\'i(.'ks, Mo., on .Inly 17, and one at Moselle, Mo., on Sep- 

 temher L'."}. On .July o, IDl'l, Mr. F]rnst Schwarz and I 

 watched one of these wasps carry an enormous Lycosid 

 spider, Dolmcdes idonciis [.) . 11, Hmerton] crossin<2: the 

 road amid many passinij^ automohiles. The wasp 

 grasped the spider's paljn in its mandihles and was walk- 

 ing hackwards, dragging the spider thus; this was no 

 easy task, and she was obliged frequently to tug and 

 strain when the spider became lodged against some ob- 

 struction. She was compelled rej)eatedly to leavi- her 

 property by the ])assing machines, but each time she left 

 it she took an elaborate flight of orientation, just as we 

 have seen other individuals of this species do when leav- 

 ing their prey when homeward bound to examine the nest. 

 Each time she returned to it readily, excepting oue 

 time when for its safety we moved it two feet to place it 

 out of the track of the passing automobiles; as we ex- 

 pected, she returned to the exact spot where she had left 

 it, and after a prolonged search stumbled upon it as if by 

 accident.
