JAPANESE HYMENOPTERA OF THE FAMILY TENTHRE-DINID^.
By C. L. Maelatt, M. S.,First Assistant Entomologist, Department of Agriculture.
The following list of sawflieB, with descriptions of new species, isbased on material presented by Dr. K. Mitsukuri, of the Imperial Uni-versity, Tokyo, Japan. Most of the specimens are supposed to havebeen taken either at Tokyo or Nagasaki. The collection is a very inter-esting one and contains many species which are striking from theirdivergence from the types of the same genera in America and Europe.This is notably the case with the genus Cimbex. Several species of thisgenus present a remarkable resemblance to our Vespas, and this resem-blance is without question a protective one. Unfortunately there issome doubt as to the localities from which the specimens were obtained,yet nearly all of the specimens are labeh'd in Jai)anesH characters,either in ancient or modern script, giving notes of locality, which are,for the most part, evidently very restricted. With the assistance ofDr. Philip .Jaisohn, and with the aid of a Japanese dictionary, I havetranslated the labels on the backs of the cards on which the specimensare mounted and have given them in brackets at the close of thedescriptions in connection with the numbers which the specimens bear.These labels are of mountains, small towns or places, particular woods,etc.; evidently localities well known to the collector, but not given onthe ordinary maps of Japan. Other labels relate to the habits of theinsects themselves, as, for instance, the Lophyrus is labeled as occurringon pine, and one of the species of Cimhex is called the "silkworm" indescrijition of its cocoon, and another, the "bee," indicating its resem-blance to some wild bee. All of the specimens are mounted on largetiat cards, with the wings and legs beautifully spread, atiording a veryready means of studying all the structural features except those of thecentral area of the lower surface. Most of the species in this collec-tion prove to be new. This would seem to indicate that the insectfauna of Japan, at least in this family, is but scantily worked uj). Inall twenty-six new species are described.Proceedings U. S. National Museum, Vol. XXI?No. 1157. 493
