THE RISE OF THE KISSING-BUG

Years ago the United States Bureau of Entomology received from an exasperated clergyman in Georgia a dead insect, enclosed in this note:

"Prof. Riley: What is this devil? He sailed down on my hedge. I took hold of his lone front leg, and as quick as lightning he speared me under my thumb nail and I dropped him. My thumb and whole arm are still paining me . . . "

The miscreant was a fine specimen of Reduvius personatus, the cone-nosed blood-sucker, soon thereafter to achieve heights of newspaper notoriety together with its cousin, Melanolestes picipes, as the "kissing-bug." How many persons died (in type) from kissing-bug bites in the year of enlightened civilization, 1899, will never be known. But from far and near, from California and Connecticut and the Carolinas, from Minnesota and Maryland and Maine, came startling reports of this hitherto unfamed creature's depredations upon the human countenance. Thereby the spider family was relieved of much unmerited odium, for it is more than suspected by entomologists that a large proportion of so-called spider bites are really the work of the more vicious but less formidable-appearing kissing-bug, as is often evidenced by the nature of the puncture.

The kissing-bug is about half an inch in length, flat-backed, shaped in geometrically regular angles, and armed with a large, hard beak. It is this beak which does the damage, for the kissing-bug is a fighter and will risk a prod at anything that gives it cause of offense. Testimony is not lacking that it sometimes punctures the human epidermis with a view

to obtaining blood at first hand instead of from its natural prey.

But the curious feature of the kissing-bug's bite is its after effect. Neither the southern Reduvius nor the northern Melanolestes possesses any venom apparatus. Now, an insect without fangs (or sting), duct, and poison gland, can no more envenom the object of its attack than a fish can kick a man to death. Yet we find such authorities as Dr. L. O. Howard, the United States Entomologist, Professor Le Conte, Mr. Charles Drury, of Cincinnati, and others, including a mass of medical witnesses, declaring from first-hand observation that the kissing-bug bite causes much swelling and severe pain. Le Conte, indeed, compares the effect to snake bite, and states that people are seriously affected for a week. A case is recorded from Holland, South Carolina, where there were vomiting and marked weakness. Mr. Schwartz, an expert of the Bureau of Entomology at Washington, was bitten twice upon the hand and testifies to the painful effects. In 1899, when the species was very common in Washington, the Emergency Hospital had a long list of patients who appeared on the records under the heading, "Insect Bite."
