Sinopsis

Excerpt from Alaska, Vol. 9: Insects, Part II

IT was originally intended to publish the entomological te sults of the Expedition in a single volume, but when the reports from the various specialists came In, the quantity of matter was so great that it was found necessary to divide it into two volumes. The present volume contains papers on the Diptera, Tenthred inoidea, Sphegoidea, Vespoidea, Formicidae, and Hymenoptera. In the latter group, Mr. Ashmead tells us, less than 30 species were known from Alaska prior to the Harriman Expedition, while the number here recorded is 335, of which 201 are de scribed as new to science. This extraordinary increase is due almost wholly to the indefatigable activity of the entomologist of the Expedition, Professor Kincaid.
