Selander, 1954 64 Toluca to Temascaltepec June 2 Drove from Toluca a few km. W where the road turns to Temascaltepec and Sultepec. The road is in terrible condition and it is possible to go only about 6-10 mi. per hour. Passed through forest stands of pine, then several good stands of fir (large trees). On shoulder of the Volcande Toluca the land is fairly flat - meadow rimmed with stands of pine - fir being not too common. After passing over the shoulder of the Volcan the road descends trough similar country, crossing several canyons. Finally we reached Temascaltepec canyon - one of the largest in the area and descended to about 7500 ft when we camped in a stand of tall oaks for the night. There seems to be plenty of habitat for megalopterus all along the way - and the oak-pine forest at head of Temascaltepec canyon is probably very good habitat. June 3 Descended Temascaltepec canyon, passing Real de Arriba about 3 mi. E Temascaltepec. Before reaching Real de Arriba we stopped and hunted in pine-oak near a small stream - finding Ptililo fusceus and Aimophila rufescens. Bonnie thought she saw a Coctius wren (gularis) in a thicket by the road. Descending to Real de Arriba we found pines on the top of the canyon and a stands of mixed-oak - other broad-leaf temperate trees in the gulleys. Not a great deal of land is farmed owing to steepness of canyon, but on level areas on either side of the canyon the dry pine forest has been cleared and planted. The vegetation around
