Jalisco '46 Lipilo fusca 45. Sierra de Tajalpa, 1-1/2 mi. W of Sayula, 7450 ft., Jalisco, Met. to Guadalajara, 5200 ft., Jalisco, Met. Aug. 6, 1946 fuscae were noted. fast the crest of the ridge a juvenal P. fusca was collected in a cornfield about 1/4 mile from the limits of C. Guzman. The country all the way is a north-south agricultural val- ley, with Ciudad Guzman lying at the south end of the valley. The surrounding hills are low, and mostly scrub-covered, with a few pines along the crests. C. Guzman is at an elevation of 5100 ft. We returned to the same cornfield from which we had collected the juvenal P. fusca and took 1 Melozoa piopieri and 3 adult Brownlowbees. Lowbees are quite common here, but fly into the cornfields when disturbed, and are impossible to find. They seem to inhabit brush-filled barrancas between fields, and are also found on small knolls near the fields. These two knolls are covered with xerophytic shrubs, and with small candelabra cactus. Lowbees were noted commonly all the way back to Camino Nacional No. 4, through San Andres Xitlean, Sayula, Atoyac R.R. Station, and Zacualco. They were noted on the crest of the ridge just south of C.N. No. 4. The valley running through Zacualco to Sayula connects with C.N. No. 4 farther west, and a playa
