Type: 9, Ronnemolla, Scania, Sweden (Lund). Biology: Nielsen, 1928, Entomologiske Meddelelser, vol. 16, pp., 152-155. Scape and pedicel whitish in front; mesothorax entirely black except that subtegular ridge is white. We studied a female of this species from Sweden, determined by A. "Roman, and the types of pallipes and caudata. These differ from Nearctic material only a little in color as indicated in the key. Nielsen reared the subspecies in Denmark from Theridium lunatum, Epeira, diademata, and E. quadrata, and described its early stages (loc. cit.). lb. Sinaraehna pallipes strigis (Howard), new combination Polysphincta (Zatypota) strigis Howard, 1892, Proc. Ent. Soc. Washington, vol. 2, p. 291; 9. Type: 9, Sea Cliff, N. Y. (Washington). Differs from the European subspecies as noted in the key. The entire mesothorax and prothorax may be reddish fulvous, or only the mesopleurum, or only a posterodorsal area of the mesopleurum. The cocoon of the type is cylindric, with rounded ends, 6 mm. long by 2 mm., of densely spun yellow-brown silk with a small amount of loose silk on the outside. Specimens (15cf, 409): From Alaska (Mount McKinley at 1,600 and 2,500 ft.); Alberta (Edmonton); British Columbia (Lillooet, Robson, shore of Shuswap Lake at Salmon Arm, and Vancouver); California (Fish Camp); Maine (Bar Harbor, Casco, and Machias); Michigan (Marquette Co.); New Hampshire (Dolly Copp Camp in the White Mts., Mount Madison, Pinkham Notch, and Randolph); New York (Ithaca, Lancaster, Mc
