P. PEARSON 1951-1952 Liolaeemus (cont'd) 3 I dead Flecturo. always composed themselves on close to their rock were fully exposed, almost at angle to sun's rays. April 20 Big & appeared by q-rock between 7:45 and 7:55a; 7:58 ran 5 feet to back on dead grass, some jumping. 8:00 fly took off west to me, probably its first flight of the day. 8:01 & came 30 ft. toward me, more jumping (push-ups). 8:10 & onto rock. 8:28 larger & appeared from down-gulch and chased; at 8:20 still flying at his tail as they ran. 8:40 a & walks up gulch to one of the normal grass berches 5 ft. from q burrow. When approached he walked on toward q rock but not into burrow, tip of his tail rustling. At 10:20 fast tethered w/d 2ft. from q rock. 10:28 saw molly-tailed & approach, jumping, duck on q rock, then at 10:30 attack repeatedly. This & lives under a rock about 20 ft. from q rock 5 km. E. Lago Drake April 22 At 6:55 a.m. encountered a large ♂; rectal 19°, substrate 5° (sand), air 23°F. Temp. at 7:05 under a bigged rock (but no bigged) was 4½°; at about 8:00 set up to take movies of molly-tailed ♂ (#3829). Tethered a ♂ outside his burrow and another outside burrow of ♀. the former approached me, then passed me to my left. Just after passing me another bigged dashed from up behind me and disappeared behind a sand & were "inspecting", finally settled in a copulatory position; the ♂ with a firm bite on side of q neck. I held this position for 15 minutes without a wriggle while I took movies from 15 feet. Finally q wriggled + broke loose, they rolled side by (for about 1 minute), then q dashed off behind Flectures. ♂ then stood up higher, did his dance while ♀ sat q patient. Then q dashed back but ♂, and ran off again (see movies). Cought her in a hole under Flectures - lots of dry Flectures stuff, old tunic tunnel. ♂ then backed home and fought with 2 catters in front of his burrow. April 23 Caccereberg 15, 200ft.
