Two species of the chewing louse genus Ricinus are redescribed and illustrated: Ricinus dalgleishi Nelson, 1972 from Helmitheros vermivorum (Gmelin, 1789), a new host-louse association, and Ricinus tanagraephilus Eichler, 1956 from Euphonia laniirostris d'Orbigny & Lafresnaye, 1837. Also, new host-louse associations are recorded for Ricinus vireoen- sis Nelson, 1972 from Vireo pallens Salvin, 1863, and for females of an unidentified species of Ricinus sp. from Corytho- pis delalandi (Lesson, 1831), which are described and illustrated.

The new species Myrsidea alexanderi is described and illustrated ex Pheugopedius maculipectus (Troglodytidae) from Honduras. Redescriptions and illustrations are given for both sexes of Myrsidea chiapensis ex Calocitta formosa from Costa Rica, and the male of M. dissimilis ex Progne chalybea from Brazil. Also, seven other previously known species or subspecies of the louse genus Myrsidea are recorded and discussed from passerine birds of the Neotropical Region, as follows: Myrsidea antiqua, Myrsidea balteri, Myrsidea diffusa, Myrsidea nesomimi borealis, Myrsidea paleno, Myrsidea psittaci and Myrsidea serini. Our data increase knowledge of intraspecific morphological variability within these species, and also of their host and geographical distribution. New host-louse associations are: Agelaioides badius for M. psittaci; Basileuterus culicivorus and Myiothlypis leucoblephara for M. paleno; Mimus saturninus for M. nesomimi borealis; and Icterus dominicensis and Molothrus rufoaxillaris for Myrsidea sp.
