These Insects approach the Megachiles, whilst the Stelides are connected with the Anthidia(l). Other Apiarire, tho Cuculinre, similar to the preceding ones in their posterior tarsi, and in which, as in the latter subgenera, the labial palpi have the form of squamous setre, and the abdomen is destitute of a brush in both sexes; that are parasitical, like the Crelioxydes and Stelides; sometimes almost glabrous and similar in colour to Wasps, and sometimes pilose in patches, have an· elongated and truncated, Ol' short and almost semicircular labrum, and narrow, pointed mandibles, unidentated at most on the inner side. The pat'aglossre are frequently long, narrow, and setaceous. The scutellum in several is emarginate or bidentated; in others ·it is tuberculous. They are the Nomadre of Fabricius. Several of these Insects appear early in the spring, flitting near the earth or about walls exposed to the sun, in order to deposit their eggs in the nests of other Apiarire. It is this habit, analogous to that of the Cuckoo which induced me to name them Cuculinre. ' In some, almost always glabrous, the paraglossre are much shorter than the labial palpi. Sometimes the labrum forms an elongated triangle truncated at the end, and inclined above the mandibles. There are never more than two complete cubital cells. AMMOBATEs, Lat.
