146 Psyche [October 



The cage was now turned 180°, all other conditions remaining 

 unchanged. The Chionea at once demonstrated its positive 

 phototropism by running in a straight line towards the light. 

 Arrived at the glass-covered part, however, it turned aside without 

 going under it. After a little while, it was seen to go under this 

 glass cover for a short time, but soon came back and returned across 

 the whole uncovered field, coming to rest at the edge of the other 

 glass cover, which was now on the darker side of the cage. Left 

 to itself, the Chionea would sometimes tumble down from the 

 wire-netting of the cover, and run about for awhile on the snow or 

 earth. However, it always soon climbed the glass wall again, and 

 took to its former place in the open part of the cover, which, 

 exposed to the draft, was probably colder than the snow. 



To test out whether Chionea really preferred the open region 

 because of its being colder, I warmed my hand by means of a hot 

 electric light bulb, and could, by coming near it with the heated 

 surface of the hand, drive the insect from the open field of the 

 cover into the space under the glass cover. I concluded that the 

 Chionea, as a rule, seeks out the coldest place it can possibly find. 

 The experiment was then closed. 



On November 25, in the morning, the Chionea was found sitting 

 at the under surface of the glass cover which was covered with 

 hoar-frost. The snow in the cage was partly melted, and the 

 resulting humidity had formed an ice-crust on the glass cover. 

 The Chionea seemed perfectly at ease while resting on this icy 

 surface. 



Towards noon I brought the insect out into the open air to the 

 edge of the balcony, on which fresh snow had fallen. It was 

 watched but otherwise left entirely to itself, and was seen running 

 over the snow alongside the whole railing of the balcony, the di- 

 rection being against the wind (positive anemotrop?). It kept 

 itself somewhat on the inner side of the railing on the side of the 

 house, but pursued its course in a nearly straight line. Only once 

 it turned to the outer side and had to be driven back to prevent its 

 falling from the balcony. Three times it went to the left (the side 

 of the house-wall), going below the edge and to the underside of the 

 snow-layer covering the railing, remaining quiet for a short time, 

 but each time returned soon to the surface of the snow and con- 

 tinued its walk. Though on these three occasions it came near to
