THE HEMIPTERA OF THE ADIRONDACKS The first records of the Hemiptera of the Adirondack Moun tains, published by MacGillivray and Houghton in 1903, were col lected during June, 1901, in the vicinity of Axton at an elevation of about 1,600 feet. This paper includes 53 species, 34 Heterop tera and 19 Homoptera respectively. A ,few years later Van Duzee* published a list of the species of Hemiptera known to occur in the Adirondacks. The latter, based on a few days' col lecting at Lake Placid and Saranac Lake Junction in 1902 and the forms enumerated by MacGillivray and Houghton, contains 193 species of Hemiptera (92 Heteroptera and 101 Homoptera).
The present list enumerates 397 species and varieties of Hemip tera, 218 Heteroptera (one lygaeid not determined), and 179 Homoptera. All the species are from the vicinity of Cranberry Lake and 95 per cent or more of the forms occurring in this region have been taken on about 200 acres of the Barber tract. How ever, this portion of the tract is represented by a marked variety of ecological and biological conditions. It includes camp site, hills, marshes, bogs, beaver meadows, lumbered areas, forests, tote roads, trails, open areas, dense growth of young trees, burned over areas, coves of Cranberry Lake and the like. The following species, listed by Van Duzee, have not been taken in the vicinity of Cranberry Lake: Homoptera Lepyronia 4-angularis Say Nttet ocephala lutea Walk. Macropsis 3-maculata Fh. Deltocephalus debilis (probably abdominalis Deltocephalus compactus 0. & B. Aconura acuticauda Bak.
Chlorotettix viridis Balclutha osborni, Van D. Trioza 3-p-unctata Fh.
Heteroptera Physatocheila plexa Say Corythucha juglandis Fitch (probably pallipes Parsh.) Xyloco•is (Piezostethus) galac tinus Fieb.
Phytocoris conspersipes (brevi usculus) Rent.
Calocoris uhleri (tinctus) Van D Dichrooscytus elegans Uhler Halticus apterus (Linn.) Strongylocoris (Stiphrosoma) croceipes (Uhl.) Pilaphorus clavipes Uhler MS Ceratocapsus (Melinna) mod estus Uhler.
Orthotylus chlorionis Say. Orthotylus (Diommat us con grex Uhler dorsalis Prov. Orthotylus (marginatus Uhl) (Cyrtorrhinus) marginatus Uhl.) Plagiognathus obscures Uhler The above list includes 23 species of Hemiptera (14 Hetcroptera and 9 Homoptera) not collected in the Cranberry Lake region. This gives a total of 409 species of Hemiptera for the Adirondack Mountains. However, the three papers taken together do not represent a complete list of Hemiptera for the Adirondacks. In fact the last day's collecting added four new species to the Cranberry Lake region. On the other hand, collecting in other parts of the Adirondacks where numerous trees and food plants occur, which are not found at all in the vicinity of Cranberry Lake, will undoubtedly add many new records.
Van Duzee * catalogues 381 species of Hemiptera (197 Heterop tera and 184 Homoptera) for Buffalo and vicinity. The Buffalo list covers several times as much area as the Cranberry Lake region covered by the authors.
