    only one, Gerris rufoscutellatus, a widespread species, was observed. Of the small number of Hymenoptera captured, the most interesting were two species of ants discovered in a decay- ing pine stump. They were representatives of two genera (Lcptothorax yankee kincaidi Pergande and Formica neoru- Jibarbis Emery), and, with the exception of one species, are the first members of this group to be recorded from Alaska. The Formica was subsequently found as far west as Kadiak. Excepting a few bumble-bees (Bombus juxtus Cr.), no other representatives of this order were seen, aside from two species of saw-flies. One of these (Tenthrcdo erythromera Prov.) was already known from Vancouver Island, while the second was a new species of Monophadnus (M’. insularis Kincaid). Only two species of Lepidoptera were captured — moths of the families Geometridee and Tortricidse. Rheumaptera has- tata L. was very common here, as well as at several localities subsequently visited. The second species has been described by Dr. Fernald as Phoxopteris kincaidiana sp. nov. Eight spiders and two Myriapods complete the list of captures at this point. Both of the latter are of interest, one of them (Parajulus alaskanus Cook) being new to science, while the other, a little hairy Diplopod of the genus Polyxenns (A*. pugetensis Kincaid), was originally described from the State of Washington. FOX POINT July 26—2J.—This name is applied to an Indian village at the extreme southeastern corner of the Alaska mainland. It was once populous, but is now deserted. It was the last station touched at by the Expedition on the return journey. Although the season was well advanced for this section of the country, some summer plants were still in bloom, more especially certain of the Umbelliferae. At these plants 23 species of Diptera were captured, the most notable of which were Syrphidae : Pipiza pisticoides Will., Syrphus velutinus Will., Sphcerophoria sulphuripes (Thomson), Eristalis flavipcs Walk., Eristalis obscuris Loew, Criorhina armillata O. S.,
