Hanken, James 1978 Journal 10 Dec Hotel Mansion Imperial, Oaxaca, Est. Oaxaca, Mexico Yesterday Tom and I took a ½ day trip to the locality above El Tejocote to try once again to get more Thorius. Again we were unsuccessful. The forest was very dry. As this area is lower in elevation than most Thorius localities in Oaxaca, dry season collecting is not possible: if I want to look again, it will have to be during or soon after the wet season. We returned to Oaxaca at mid-day and took the rest of the day off, including a visit to Monte Alban. 11 Dec Yesterday Tom and I visited Thorius localities W of San Vicente Lachixio to get samples of the second of two species for which I have only two for electrophoresis. The first was 16.1 km W and I presume it to be the same place as 15.5 km W three summers ago. There is a large meadow with a small rivulet, all surrounded by pine and pine-oak woods. Fallen logs are abundant and we worked for a couple hours, finding Thorius but only locally (i.e. concentrated in a few logs). This locality is very reminiscent of the locality W of Zaachila, Oaxaca both in the Sierra de la Altepetlac. Three Cochranas and Centrolutes and Scelophorus were also taken. The second locality is a steep, shaded slope 13.6 km W (presumably equivalent to the previous locality 13.2 km W). Again, rotten logs were abundant and we collected
