PROGRAM. 



E. R. Sasscer, a Brief Resume of the Family Coccidae. (Presidential 

 address.) 



Mr. Sasscer discussed briefly the history of the study of the Coccidae; 

 distribution and number of species; economic loss caused by these in- 

 sects; useful products such as shellac, cochineal and other dyes, wax, 

 and ground pearls, the last the empty shells of the genus Margarodes; 

 habits in relation to oviposition, part of plant attacked, and gall- 

 making; methods of distribution; natural enemies; and works on the 

 family. Of special interest was the suggestion that Cryplophyllaspis 

 liquidambaris, which forms galls on the leaves of sweet gum, may be a 

 form of Aspidiotus ancyhis, which is always found on the twigs of trees 

 bearing galled leaves.
