She sometimes bores three canals in the same piece of wood. They are peculiar to warm climates( 1 ). The labial palpi of the other Apiarire are in the form of squamous setre; the two first joints, compared with the two last, are very large, compressed, scaly, and have a membranous or tJ·ansparent margin. The maxillary palpi are always very short, and frequently consist of less than six joints. The labrum, in a great number, is elongated and inclined on the mandibles, sometimes forming a long square and sometimes an elongateu triangle. The Apiarice, which in our work on the natural families of the animal kingdom we have collectively designated by the name of Dasygastrre, are remarkable-as intimated by that name-for the numet·ous, short, cr·owded hairs, forming a silky brush, that almost always(2) covers the abdomen of the females. The labrum is as long as it is wide or longer, and square. The mandibles of the females are strong, inCisive, triangular and dentated. The paraglossce ar~ always very short, squamous, and pointed at the extremity. Of all the subgenera of this little group, that which appears to us to approximate most closely to the Xylocopce, and which alone presents maxillary palpi consisting of six joints, and wings furnished with three complete cubital cells, is the CERATINA, Lat. Spin. Jur.-Megilla, Prosopis, Fab. The body is narrow and oblong; the antennre are 'inserted in little fossulre, and terminated almost in an elongated club; the mandibles are sulcated and tridentated at the extt·emity; the ab.domen appl ·oaches to an oval, and is destitute of a silky br·ush. 'rhe labrum is proportionally shorter than in the following subgenera, where it forms an elongated quadrilateral. According to the curious observations of M. Maximilian Spinola-Ann. du Mus. d'Hist. Nat.-the habits of the females are the_ same as those of the Xylocopre(3). (1) Lat., Gener. Crust. et Insect., IV, 158.' To this subgenus, until we have further examined it, we refer the genus Lutia of Messrs Lepeletier and Servillex, 795. (2) The Ceratinae, Stelides and Crelioxydes, although destitute of a ventral scopa, should make part of this group, on account of the form of the labrum and man· dibles, and other general characters.
