The animal kingdom, arranged after its organization : forming a natural history of animals, and an introduction to comparative anatomy . subgenera. Pepsis, Fab., has the labrum apparent; the antennae in the males straight; the maxillary palpi not much longerthan the labial; the males have the hind tibiae and tarsi compressed. AH the species are exotic, especially SouthAmerican, and have the wings coloured. Ceropales, Latr., has the labrum and antennae of Pepsis, but the maxillary palpi are much longer, with veryunequal-sized joints. Pompiliu, Fab., resembles Ceropales in the latter respect, but the antennae of both sexes are convoluted andcomposed of loose joints ; the labrum is but slightly exposed. Type, S. viatica, Linn, [a common species]. Theseinsects provision their nests with Spiders, having first pricked them with their stings. Salim, Fab., is established upon the males of some species which have the pro- and metathorax proportionablymore elongated than in Pompilus, and the mandibles are not toothed. Planiceps, Latr., differ from Salius in havmg the head flat, with the posterior margin concave, the ocelli very. HYMENOPTERA. 595 small and distant; the fore-wings have only two complete cubital cells, the second of which receives the firstrecurrent nerve. Aporus, Spinola, has also two complete cubital cells, but the second receives the two recurrent nerves ; in otherrespects they entirely resemble Pompilus. The others have the first seg^nent of the thorax narrowed in front like a knot, and the first abdominal segment,and sometimes part of the second, narrowed into an elongated peduncle; the upper wings have always three perfectcubital cells, and the commencement of a fourth. Ammophila, Kirby, has the mandibles dentate, and themaxillae and labium very long and proboscis-like ; the secondcubital cell receives the two recurrent nerves. T>T)e, Sphexsabulosa, Linn, [a very common British species], the femaleof which provisions her nest with caterpillars. Miscus,
