Mr. J. Chester Bradley has begun, in the May number of the “Entomological Student,” a monographic revision of the Evaniidœ of North America, a work badly needed by our students.

On learning from me that I had several new species in this family, he has requested that I should publish them at once, so that they may be incorporated in his monograph, which will be published in the Transactions of the American Entomological Society of Philadelphia.
