The materials have been derived principally from the collection of Baron R. Osten Sacken, of the Russian Legation in Washington, kindly intrusted to the author for examination.

The Institution is under obligations to Baron Osten Sacken for editing the work, adding species described by Dr. Loew subsequent to the reception of his manuscript, and for correcting the proofs. He has also added a monograph of the Cecidomyidce, a group of much interest, and one to which it was considered of importance to call the early attention of investigators. JOSEPH HENRY, Secretary S.
