quitoes, and other insect annoyances, were present in great variety, 
while the humidity was always high. In the life of the field nat¬ 
uralist, the abundance and persistence of insects which prey, and 
humidity' which enervates, are serious matters. 
The wealth of life, both animal and plant, in this great lowland 
forest appears inexhaustable, and steadily continued work accum¬ 
ulates wonderful collections; but constant application, with pains¬ 
taking examination of first one, then another type of habitat, fin¬ 
ally shows results in a marked reduction of previously unseen 
forms. This forest, however, was the richest piece of country, 
from the insect standpoint, examined by the expedition. 
In the vicinity of Aracataca other pieces of forest, relatively dry 
in character, heavily matted jungle scrub and meadow land of 
rank grass were also studied, and yielded in their turn important 
collections. Iguana lizards scuttled about the wine palms in the 
compound of the United Fruit Company; and bats, which roosted 
in hundreds in the attic over our room, tried collecting the insects 
attracted to our gasolene lights on the veranda. The bats were 
discouraged by our collecting some of them, and our lights continu¬ 
ed to be centers of insect attraction. From Aracataca wereturned to 
Bolivar, packed our collections, and sailed for home in late August. 
As a result of the expedition the Academy was enriched by a col¬ 
lection of seven thousand seven hundred specimens of insects, of 
which four thousand four hundred were representatives of the 
order Orthoptera, the chief object of the field work of Messrs. 
Rehn and Flebard, as well as a moderate-sized collection of reptiles 
and amphibians, and a few mollusks. The greatest result of the 
work, however, was the accumulation of quantities of original ob¬ 
servations made in the field, in numerous cases on species regarding 
which no knowledge of their habitats and occurrence exists in scien¬ 
tific literature. This information can be secured only by trained 
observers, and collections made without such correlated observa¬ 
tions fall, to a very considerable degree, short of the full usefulness 
which could be theirs. These notes will be utilized as the detailed 
study work on the collection progresses. 
The Academy is under lasting obligations to Mr. Orlando L. 
Flye and Mr. M. A. Carriker, Jr., for their untiring kindness and 
courtesy and invaluable assistance, and also to their respective 
families for their cordial hospitality to its representatives. The
