the main street of Bejuma to the Bejuma River and followed 

 down stream all day. The river is about fifteen to thirty feet 

 wide, in a sand or gravelly bed, shallow pools alternating with 

 gentle ripples, and the banks, immediately adjacent to the 

 stream, are largely covered with wild cane. There are less 

 frequent growths of small trees and occasional open spots of 

 grass or solid spreads of convolvulus. Where we left the river 

 in the afternoon some round, grass-covered hills lay on the 

 left bank, and between these hills and the river was a small, 

 poorly tended and sickly coffee planting with a few large shade 

 trees scattered through it. At the foot of the hills at the edge 

 of the coffee planting were a few small swampy spots. 



After the day's collecting we found in Jesse Williamson's 

 material a single slightly teneral female Archaeogomphus which 

 he failed to recognize when it was captured, but which he 

 knew he load collected somewhere on the river. On February 

 18 I returned to the river to search for more specimens of 

 the species. Cutting across country, I struck the river at the 

 coffee planting, which, in view of our observations of A. 

 lianuitus in Colombia, seemed to me the most likely spot along 

 the river for specimens of the genus. A thorough search 

 over the entire coffee planting yielded nothing, so I started 

 up river, working carefully adjacent cane patches, dry woods, 

 a small banana field, and the broad expanses of waist-high 

 convolvulus leaves, but without success. About two miles of 

 the river was thus worked and I then returned, working down 

 stream as carefully as I had worked up, and arriving without 

 success about 4 130 p. m. at the coffee planting. Here I found 

 many small libellulines resting on the tips of the dead twigs 

 of the coffee trees (really bushes). These libellulines were 

 busily inspected for half an hour in the hope of detecting an
