SO that they may be properly studied. Small card boxes, or if these 

 are not to be had, large envelopes are generally used to send scale 

 insects through the mails. With the insects there should always be 

 enclosed, when possible, the following information : locality in which 

 the insects were collected, date of collection, name of food plant, name 

 of collector, extent of injury to the plant, and any other remarks that 

 may seem desirable. 



We are indebted to Dr. C. L. Marlatt for verifications of species 

 and to Prof. Herbert Osborn for literature used from his excellent 

 library on Coccidie.
