CoLLEcTING In SoutH AmericA.—L. A. Williamson, E. B. William- 
son and B. J. Rainey, of Bluffton, Indiana, left New York City by 
steamer on January 15th for British Guiana, and returned to New 
York March roth. On their trip south their first stop was at Bar- 
badoes, where they made only a brief stay, and from there they went 
to Georgetown, British Guiana, and with very slight delay struck 
into the interior, ascending the Demarara River sixty miles to Wis- 
mar, where they spent a few days in the collection of dragon flies, the 
main purpose of the expedition, which was organized by E. B. Wil- 
liamson. From Wismar they crossed the country to Rockstone, on 
the Essequibo River, and collected flies for several days along that 
stream.’ Their next objective point was Tumatumari, on the Potaro 
River, about 150 miles from the coast, and in their collecting expedi- 
tions in that vicinity they ascended the river still twenty miles farther. 
From there they returned over about the same route to Georgetown. 
From Georgetown the three gentlemen went to Paramaribo, the 
capital of Dutch Guiana, and also visited New Amsterdam in that 
country, adding to their collections at both points. This completed 
their collecting tour in South America and they then took a steamer 
to the Island of Trinidad, where they spent two weeks in collecting 
before they took up the return journey to New York. 
They secured a total of about 4,100 dragon-flies, of 135 species, and 
in addition about 500 insects of other orders. 
The dragon-flies secured in South America by Mr. Williamson will 
be added to a collection of about 23,000 he had made previously, which 
includes about I000 species secured on former expeditions to many 
points in the United States, Canada, Mexico, and Central America.—
