On November 3rd, 1928, I collected at Stone Mountain, Georgia, a Carabid beetle—Dicaelus elongatus (Bon.)—which gave off a very strong discharge of gas which turned to a dense smoke. This appeared to come from the sides of the thorax, instead of from the posterior end of the abdomen as in the genus Brachynus.
