According to Mr. Smeathman these bees are very injurious to wooden houses, the posts of which they bore and perforate in various directions, so as to weaken them very much. The holes they make are half an inch in diameter. Drury hazards the conjecture, that the curiously dilated anterior tarsi, and the long hairs with which it is furnished, appear to be useful to the creature for containing the substance of which these insects compose their nests. This, however, is but mere conjecture; since it is the males only which possess this curious construction; and this sex takes no share in the construction or provisioning of the nest in any species of bees with whose economy we are hitherto acquainted. There are certainly several distinct species confounded together under the common name of Xylocopa latipes. SYNAGRIS CORNUTA [male]. Plate XLVIII. fig. 3. ORDER: Hymenoptera. SECTION: Diploptera.

Front of the head dark orange, the hinder part brown. Antennæ dark orange brown, and about the length of the thorax; the basal joint elongated. Ocelli distinct. From the front of the head proceed two slender horns, about three-eighths of an inch in length, of a solid bony substance, bending at the extremities toward each other, which the insect can open and close together horizontally, and which are the mandibles greatly developed. The base of these horns extends downwards, and forms a kind of {99}hollow beak, terminating in a point which encloses the tongue, and serves as a guard or fence to secure it from external injuries. Thorax and legs orange brown. Abdomen probably of a dark mazarine blue [?] when the insect was living, but is now of a dead black. Wings brown, opake, and shining. PLATE XLIX.
