Dr. Hammond and I tried this formula during last Summer, 

 but with little or no success, we also soaked strings of dried 

 apples in the mixture and placed them on the trees with the same 

 result, I then plastered some decayed bananas on the bark of the 

 trees, from which we captured a few Catocalae and numbers of 

 small Noctuae. I have no doubt but the decayed fruit if fairly 

 tested and tried would be a success, either bananas or pears. To 

 collect at night you need only your collecting-box, bottle, and a 

 lantern; I painted or baited the trees about waist high and a few 

 inches square, then with a leather belt around the waist, with a 

 dark lantern fastened thereto, I could walk up to the trees with 

 my hands free and plenty of light. I noticed on nights during 

 an electrical storm, i.e., plenty of flashes of heat lightning with 

 no thunder, there were few or no specimens of any kind. 



The following table will give the time of appearance of the 

 different species in the vicinity of Frankford, Philadelphia, com- 

 piled from my diary of several years. I might remark that 

 north or south of here would make a few days difference either 

 way, and again after a dry hot Spring would make ten or twelve 

 days difference.
