.4fe/rac/.—Fogging ot^the high forest canopy in Panama yielded 15 species ofa genus
previously known from few specimens from scattered Neotropical localities. The addition
ofotherCentral American specimens, includingthe previously describedA', compta (Duda)
and A', schildi Duda, made a total of 18 species, ofwhich 16 are new (one left unnamed).
New species of Notaulacella are vitlata, spinosa. biiscki. cabimae. albitarsis, polita. pau-
cipilosa. octicola, :eleki. lineigena, sagittata. broadheadae, ligatura, tripunctata, laterivit-
tata.
