NOTES ON SAWFLIES, WITH DESCRIPTIONS OF NEW SPECIES. By S. A. RoiiWER. 0/ the Bureau of Enlomology, United States Department of Agriculture. The following paper, which deals %vith sawflies collected from various parts of the world, is presented for publication now because it contains miscellaneous new species and notes which can not well be included in any revision in progress, and as some of the new species are of economic importance it is desirable that their names be made available. Some of the sawflies were collected by Messrs, Bryant and Palmer, in Java. All of these species have been worked up, and as all of them were new, a complete report of the sawflies of this expedition will be found on the following pages. Most of the Nearc-tic species described have been received for determination through the Bureau of Entomology. A synopsis of the Nearctic species of the genera Lagium and Labidia is included, as it may be useful in determining the species described as new. This paper, which is the second stated contribution from the Branch of Forest Insects, Bureau of Entomology, which has appeared in these proceedings,^ is the result of work on miscellaneous material accumulated by the bureau and from the collection of the Museum in connection vnih the study of sawflies injurious to forest trees.
