While making an intensive study of the bark beetles of Western North America, I noticed that two of the species in the genus Carphoborus were new. Since the last key to the species of this genus has been compiled (Swaine, 1918) Dr. Swaine has described five new species which with my two would more than double the number in the genus. I therefore feel that a new key should be made.I am indebted to the Museum of the California Academy of Sciences for the use of its collection of this genus, and to Dr. E. C. Van Dyke of the University of California for his helpful criticisms.

Species Descriptions

Recent examination of a large number of Rhyacophilidae has resulted in the establishment of some very interesting distributional records as well as the recognition of several new species. New species, descriptions of hitherto unassociated females or little known species, and new distributional records in the Rhyacophila, Glossosoma, Anagapetus, Agapetus, and Atopsyche are discussed in this paper I would like to take this opportunity to thank Dr. L. J. Milne of the University of Vermont for the generous loan of his Rhyacophila holotypes, fourteen of which are figured and briefly described herein. Material from the University of Massachusetts is designated as (Mass.), from the University of Minnesota as (Minn.), from the American Museum of Natural History as (AMNH), from the North Carolina Department of Agriculture as (NC) and from the California Academy of Sciences as (Cal.). Unless designated otherwise types are in the writer's collection at the University of Wyoming.

Akio Baba of Osaka University combined (Chem. Lett. 2013, 42, 1551) reduction of the acid 1 with subsequent condensation with the ketene silyl acetal 2 to directly give the coupled product 3. Song-Lin Zhang of Soochow University showed (Chem. Commun. 2013, 49, 10635) that the allyl Sm reagent 5 could be added to an aldehyde 4 under reducing conditions, leading to the alkene 6. In a related development, Patrick Perlmutter of Monash University reduced (Org. Lett. 2013, 15, 4327) the interme­diate lactol from addition of the alkyl lithium reagent 8 to the lactone 7, to give the alcohol 9. Yoshihiro Miyake, now at Nagoya University, and Yoshiaki Nishibayashi of the University of Tokyo added (Chem. Commun. 2013, 49, 7854) the benzyl radical from the decarboxylation of 10 to the acceptor 11 to give 12. Yasuharu Yoshimi of the University of Fukui (Tetrahedron Lett. 2013, 54, 4324) and Larry E. Overman of the University of California, Irvine (J. Am. Chem. Soc. 2013, 135, 15342) reported related results. David Milstein of the Weizmann Institute of Science developed (Angew. Chem. Int. Ed. 2013, 52, 14131) an Fe catalyst for the hydrogenation of an alkyne 13 to the E-alkene 14. Zhi-Xiang Yu of Peking University showed (Org. Lett. 2013, 15, 4634) that kinetic isomerization of the alkene 15 led selectively to the Z-alkene 16. Umasish Jama of Jadavpur University prepared (Eur. J. Org. Chem. 2013, 4823) the nitroalkene 18 by condensing nitromethane with the aldehyde 17. Vladimir A. D’yakonov of the Russian Academy of Sciences, Ufa described (Chem. Commun. 2013, 49, 8401; Tetrahedron 2013, 69, 8516) the remarkably selective coupling of the allene 19 with the allene 20 to give the Z,Z-diene 21. Sang-Hyeup Lee of the Catholic University of Daegu assembled (Synlett 2013, 24, 1953) the ketone 24 by coupling the alkynyl aluminum 23 with the nitrile 22. Jean-Marc Weibel and Patrick Pale of the Université de Strasbourg showed (Chem. Eur. J. 2013, 19, 8765) that the alkenyl nosylate (p-nitrobenzenesulfonate) 25 coupled smoothly with 26, leading to the enyne 27. Reinhold Zimmer and Hans-Ulrich Reissig of the Freie Universität Berlin described (Synthesis 2013, 45, 2752) similar results with alkenyl nonaflates.
