Method oj Collecting. An insect net is not a satisfactory instrument to 

 use in collecting adult hanging-flies (Bittacus) which are to be used for 

 experimental purposes. These long-legged, soft-bodied insects ordinarily- 

 fly among weeds and grasses. Many individuals are injured by sweep- 

 ing the foliage or on being removed from the net. 



The instrument which I have frequently employed is a very large 

 lamp chimney, the top end of which is closed with a piece of cheesecloth 

 held in place by a rubber band. By holding the lamp chimney at the 

 elongated, closed end, the large basal opening may be quickly thrust 

 over the insect as it hangs quietly from some support. Then, after 

 making a successful grab in this fashion, one may hold the palm of his 

 hand over the opening and carry the fly to a prison box. 



A convenient box to take into the field for holding the flies that are 

 collected is one made of wood, about 18" x 16" x 12", and provided 

 with several fresh twigs of some woody or semi-woody plant to serve as 

 supports for the insects. The box should have a closable opening about 

 the size of the base of the lamp chimney. When the opening of the
