Genus AMBLYCNEMUS, Marshall, 1921

The new species of this genus described here differs rather radically from the genotype ( Amblycneinus stevensoni Marshall, Insects of Samoa 4(S):226, fig. 6, 1921) in having the femora strongly toothed. It has, however, the other peculiar characters of Amblycnemus and is, therefore, placed in that genus; I have other new species at hand which also have toothed femora.

In the original description of the genus, the statement is made that one of the most aberrant characters of the genus was the fact that the tibiae completely lacked terminal mucrones. In specimens of the genotype at hand the tibiae of the females have no traces of apical tibial mucrones; the males, however, have the mid and hind tibiae distinctly mucronate at the inner apical angles. In the new Guam species, this situation is duplicated: the males have a prominent mucro at the inner apical angles of the mid and hind tibiae, and the females have no trace of tibial mucrones.

I have before me other new species of the genus, from Fiji and the Palau and Caroline Islands. Many new species will ultimately be described from the vast area between Samoa and Guam.
