Pt. Barns, Alaska July 20 afternoon on ridge. Overcast light west wind. Insect activity apparently depressed somewhat by cold wind, but the index of activity still high. Large numbers of minute to small Chironomida (+40 per sq. meter) were present in reticulated areas between frost blisters, most of them climbing up the vegetation. Muscid activity was not as noticeable as last time but individuals were higher than preceding visit (see counts). Crane fly activity in top of polygons noticeably increased over last visit. Fungivoids dropped. Mosquitoes dropped owing to cold weather, but a few were encountered during the events. Sciarids as on the increase as also the scelidinum. Spiders were more common in counts than for any immediate previous events. The vegetation changed quite perceptibly in appearance. Petrotilus on top of the ridge has appeared with a great profusion of bloom—the stalks are about 1/2 the height of last year's dead stems, but even so stand out quite conspicuously. The Ranunculus along the beach ridge (marsh side)
