The following is a list of the principal publications of the 

 Entomologist during the year 1891 — fifty-six in number — 

 giving title, place, and time of publication, and a summary of 

 contents. A similar list of publications for the years 1875, 1876, 

 and 1877 is appended. 



The Squash Bug.* (Country Gentleman, for January 8, 1891, Ivi, 

 p. 23, c. 1, 2 — 26 cm.) 



To inquiry from Kane county, 111. , answer is made that Paris green is not 

 available against the squash-bug or any other of the bugs proper (Hemiptera). 

 The best remedies are trapping the bugs and destroying the eggs. Trap with 

 pieces of wood and kill the bugs found under them. Examine for egg- 

 clusters on the underside of the leaves, and for the colonies of the newly- 

 hatched bugs near them, and crush them. Prevent injury to the base of the 

 stalk by applying a mixture of salt and ashes.

For destroying weevil infesting a flour and feed store in Orange county,

 phide of carbon is recommended, to be used after the manner reported by 

 Professor Cook as having been successfully used for^the purpose in a mill in
