On tributary quebradas of the Rio Uraca, a beautiful stream 

 above the railroad bridge, we found capitalis and miniata in 

 about equal numbers, and macro pus about twice as numerous 

 as the other two together. These quebradas were of the inter- 

 mediate type described in the last two sentences of the pre- 

 ceding paragraph. 



49. Tucacas, \"enezuela. On the coast. Terminus of the 

 railroad, which has three inland termini, San Felipe, Aroa and 

 Barquisimeto. Back from the town is a small, boggy stream 

 three to six feet wide and one to three feet deep, sides steep 

 or overhanging, from which the town receives its water sup- 

 ply. Adjacent to the stream were literally thousands of spider 

 lilies (Crinuni) in bloom and there were many wet patches of 

 heliconias. Dry woods and dry heliconia patches were adja- 

 cent and gave evidence of flooding during the rainy season. 

 The lower part of the stream is shallower, broader, and sandy 

 or gravelly, with a few low ripples. Collected March 23-25, 

 1920. A few Hetaerina caja were taken here. 



50. Tumatumari^ on the Potaro River, about seventy-five 

 miles above Rockstone, British Guiana. Elevation not noted. 

 Country hilly and heavily wooded. Above town on the right 

 bank is a small, sluggish stream, known as Cashew Creek, 

 two to six feet wide, with a mud bed. A similar stream with 

 less flow of water is on the left river bank below the' falls in 

 the river. A trail from Tumatumari leads back into the forest 

 and about four or five miles from town crosses Tiger Creek, 

 a sluggish stream almost too large to wade. Further up-stream 

 there is a large waterfall in Tiger Creek known as Washer- 

 woman Falls. The trail from Tumatumari to Tiger Creek 

 crosses a few little streams from a few inches to as large as 

 three feet in width. They are generally muddy and some of 

 the smaller ones lose themselves in the forest. One of these
