An unnamed Coleoptera, probably exotic (x. 30) No. 3 represents a species of coleoptera, *'probably exotic and not yet recognized by any specific name in this ; "So far as we know," says Mr. Howard, referring also to lathridius, "these little beetles, feed for the most part, upon minute fungi or moulds which ac- cumulate upon vegetable matter in damp places like cellars, and it is not probable that they are the primary authors of the damage to drugs or herbs kept in ; This statement by Mr. Howard corresponds with experience, as the drugs before mentioned have been kept in a comparatively damp place. During the sum- mer vacation and in the fall before the steam was turned on the building, a considerable amount of fungoid growths had accumulated in the vicinity in which the drugs were kept. Many of the drugs had become so injured by fungus growths as to be utterly useless. The most abundant pest in the crude drug stock appears to be sitrodrepa panicea (fig. 4), belonging to the family ptinidae, a family whose members in both larval and adult stages feed on dead, dry vegetable and animal matter. This family comprises a number of small beet- les rarely exceeding a quarter of an inch in length and usually brownish in color, A promi- nent characteristic is the hood-like pro-thorax, the head being so bent or drawn back under it as to be almost concealed (fig. 4 b). The indi- viduals classified under the specific name of panicea are most abundant in this family. They are from two to three millimeters long, with the brown sub-cylindrical body almost entirely covered with many fine, short, yellowish hairs, which on the surface of the body, are arranged in parallel longitudinal lines; the upper surface of the body, the wing covers, is finely striated (see fig. 4, a). The young or larva of this beetle is a small white grub with three pairs of of legs a
