Natural size. with a short tongue, which makes it necessary for this group of bumblebees to perforate long-tubed flowers in order to secure the nectar. Because of this habit they have been given the name Disteleologists (cf. Haeckel, '66; Mtiller, '79; and von Buttel- Reepen, '14), a subject which the writer intends to discuss in another paper. The Phaneroschadonenta also have the following interesting characteristics: (i) they construct—usually near the center ot the comb—one or more bulky, waxen tubes in which they store large quantities of pollen (cf. Figs. 4 and 5); (2) the wax which they produce is unusually dark and brittle, as if mixed with black soil; and (3) their males, like those of the genus Psithyrus, are rather sluggish as compared with those of other The writer would here also like to point out that the Phanero- schadonenta appear early in the spring, that they do not nest on 6 Cf.
