Sulphur-Butterflies (Colias).* — In this family the wings are rounded, and form a gutter for the reception of the abdomen. They are the commonest butterflies we have. * In some countries they flock upon certain trees, completely covering them, so that in the sun they appear to have a golden hue. Darwin met a vast cloud of them, ten miles at sea, off the Bay of San Bias, and as far as could be seen the swarm extended. Sir Emerson Tennent observed a flock in India that was several days in passing a given point at a high rate of speed. Sir Robert Schomburgh observed a cloud of another genus crossing the Essequibo River, South America, that was nine miles wide, and was nine hours in passing the Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original Holder, Charles Frederick, 1851-1915; Holder, Joseph Bassett, 1824-1888, joint author.
