One of the species has adapted itself to life in houses, feeding upon flies and bed-bugs. The young have the curious habit of coating them- selves with particles of dust or fibre which conceals them perfectly from casual observation. A similar species, Conorliinus sangui- uigis, nearly an inch in length, is found in houses in the South- ern States,—not to feed on bed-bugs, how-ever, but as a bed-bug itself. It is especially inclined to bite children, and many cases of supposed spider-bites are believed by Dr. Leconte to be really due to this insect. He also states that he has known a patient to suffer from the effects of such a '' bug'' bite for nearly a year. Fortunately, the insects are not very common, their large size and black color, with red markings, making them easily visible and readily destroyable. The largest species occurring in the Eastern United States is the so-called 'wheel-bug,' Prionidus cristatus, and this becomes more common southwardly. It la
