A PRELIMINARY LIST OF THE JASSOIDEA
OF MISSOURI WITH NOTES ON SPECIES.
By Edmund H. Gibson and Eric S. Cogan, U. S. Bureau of Entomology.
The following preliminary list of the Jassoidae of Missouri is mainly the result of collections and notes made by the authors during the summer months of 1915. On account of the lack of records for this state the authors were prompted to undertake such a survey. As far as possible collections were made so as to embrace all conditions in different sections, giving some attention to ecological relations. The list comprises some 98 species.

Macropsis apicalis Osb. & Ball. A few specimens swept from weeds at Charleston, Mo., during the late summer.
Bythoscopus distinctus VanDuzee. Found in great numbers on willows in northern Missouri.
