R. K. Selerander 1952' 59 1350 - See Goldman Aug. 30 Mexcala, 1600ft., Guerrero, Mexico. Stopped for the night just off the highway. Vegetation desert type; candelabra cactus, mosquito common; also many low herbaceous plants including a species of morning glory = probably Arid Upper Tropical Zone. Tried collecting meloids at light but none came in; very few insects of any kind came to light. This is surprising since we had collected 5 kinds of meloids here in the afternoon of August 20. Aug. 31 Woke at 6:00. Rather wet because of slight fog hovering along the hillside. Meloids began crawling up on the vegetation (mostly low herbs) shortly after day-break. Collected good series of several species. Spent about 2 hours collecting insects. Drew down heard calling and a few other un- identified bird calls heard. (Here photograph). We then continued along the highway, making a short stop 5mi. NNE Mexcala, 2000ft., Guerrero where I collected a small lizard which was crawling up the stem of a herb about 2 feet in height (specimen # 1434). Ecological situation similar to that at Mexcala. This desert type extends from just east of Chilpancingo nearly to Taxco, being best developed at Mexcala. C. brunneiceps may occur somewhere near Mexcala - worth investigating next year. C. himidi has been taken south of Mexcala, presumably along the river, however, I doubt that himidi occurs in the cactus-mosquito formation.
