P. PEARSON 1955 Oct. 2. Leon. Met a trape tracked, even by ants. The osilae from here must have come from up in the bunchgrass. Osgood's Yola must be the one between here and Frying, not the one on the A.G.S map NE of Tilcara. I'm for part out 2 logs of trape on hill [1] mi. W of the station and about 500 ft higher: most of them along 2 stone walls. One wall through bunchgrass - [illegible] others. The other wall with bunchgrass but also lots of broken bushes, a few trees. Scored up 2 smallish trapeus with more interrupted flight than Mothfereta. Altplain side looking, but the bunchgrass line looks OK for osilae. Could see far up & down the valley. The forest on the east side only goes for a mile or so above Leon. To the south the valley becomes much wider, flatter. Oct. 3 Leon. 4th osilae, 1 Heperump, 1 Grymytoma? and 1 Maravosa, the latter in one of the highest trape, near osilae. The opy also near osilae. One osilae was in the brushy - bunchgrass line. Scored up 3 trapeus: 2 smallish, one almost as big as adult Mothfereta, but different flight. Sign at Leon station says 1622 m. The river is not more than 50 ft lower so the level on Simon's or Bordin's level (1500) are approx. Gruesome train ride from Leon to La Quiaca - 10 hours to go a little over 100 miles, garbage-filled carrels, no seat.
