The Peloprei construct rounded or globular nests of earth in the interior of houses. They are formed like a spirally convoluted cord presenting on their inferior side two or three ranges of holes, so that they resemble the instrument known in France by the name of a Tinker's whistle-siffiet de chaudronnier. The holes are passages to as many cells, in each of which the Insect places the body of a Spide1·, Fly, &c., along with an egg; it then closes the ol'ifice with earth. To this division belongs the P. apirifex; Sp!tex spirifex, L. Black; abdominal pedkle and legs yellow. In the south of France( 1 ). 4. In other Fossores the first segment of the thorax merely forms a simple linear and transverse border, of which the two lateral extremities are remote ft·om the origin of the superior wings. The legs are always short or of modet·ate length. The head viewed from above appears transversal, and the eyes extend to the posterior margin. The abdomen forms an elongated semi-cone, rounded on the sides near its base. The labrum is entirely exposed or very salient. I have formed these Insects into a small family called BEMBEOIDEs, from the genus BEMBEx, Fab., Of which it is constituted. In these Hymenoptera, peculiar to hot climates, the .body is elongated, pointed posteriorly, almost always varied with black and yellow or russet, and glabrous; the antennre are approximated at base, slightly geniculate at the second joint, and enlarging towards the extremity; the mandibles are narrow, elongated, dentated on the inner side and crossed; the tibire and tarsi are furnished with little spines or cilia, most remarkable on the anterior tarsi of the females. We ft·equently find one or two teet.h under t~e abdomen of the males. Their motions are extremely rap1d; they fht from flower to flower with a sharp and interrupted hum. Several diffuse an odour of roses. They only appear in summer. Some of them have a false proboscis, bent underneath; their labrum forms an elongated triangle.
