These capsules prepared thus, were used in 12" x 16" cabinet 

 drawers, two to the drawer. They held down the pests in a very 

 much neglected and crowded cabinet for nearly a year until I found 

 time to work over the material. In pinning the capsules into the 

 drawers I at first thought it necessary to pin them into the sides so as 

 to keep them upright, but later I pinned them into the bottom in a 

 slanting position with good results. By inserting a stout insect pin 

 obliquely to the vertical axis of the capsule (see Fig. 2), it may be 

 pinned in the bottom of the drawer and there is no chance of the 

 creosote running out. This is a fault that I anticipated but it did not

occur, the cotton absorbing all the creosote. The capsules are small, 

 not very noticeable and maintain a strong odor of the creosote in the 

 cabinet. The drawers of the cabinet were quite tight, however, and 

 were not opened a half dozen times in ten months. I believe that the 

 capsules would need refilling about once in every six months where 

 the drawers were frequently opened. 



It is better to use a small amount of cotton and not to pack it into 

 the capsule. Do not use too much creosote either. Capsules in 

 which the cotton is loose are much easier to refill. When capsules 

 are just filled, pin them in an old box set up on end and let them 

 remain a day, so that any creosote which may have run over on the 

 outside will dry before putting capsules into the cabinet.

These notes by no means aim at exhaustiveness. Much is neces- 

 sarily omitted, but as their main purpose is to unravel the tangle into 

 which have fallen the species of the genus occurring in the eastern 

 United States, it does not appear to be appropriate to go minutely 

 into details best treated of in a monographic revision of the genus.
