8 of the 10 spp. of Phyllogomphoides occurring north of South America are dealt with; 4 of these are described and illustrated as new, viz. P. suasillus sp. n. (<3 holotype: Quebrada San Pedro nr. Santa Rosalia, Zacapa Dept , Guatemala; Aug. 20, 1970), P. duodentatus sp. n. (<J holotype: Salto Eyipantla, 8 km S. of San Andres Tuxtla. Veracruz, Mexico; Aug. 15. 1976), P. pugnifer sp. n. (<5 holotype: 3 km N. of Santiago Tuxtla, Veracruz. Mexico; 13-14 Sept., 1965; 9 unknown).and P. insignatus sp. n. (6 holotype: 1.7 mi N. of Gamboa, Canal Zone. Panama; 8-15 Aug.. 1970). — The characterization of the genus Phyllogomphoides is discussed, and the view is advanced that L.K. GLOYD's rejection of Negomphoides was correct (1973. Occ. Pap. Mus. Zooi Univ. Mich. 668: 1-7). and that the name Phyllogomphoides should be applied to the spp. originally placed in Gomphoides, except for infumata, praevia, and perdita, and for those spp. that have been separated into Phyllocycla and Aphylla.
