Deleve Institut royal des Sciences naturelles de Belgique, Brussels, Belgium Almost all of the specimens discussed in this paper were collected by Dr. C. C. Blickenstaff at Suakoko, Liberia, most frequently by light trap. I presume that they were captured during their first flight, just after eclosing. Indeed, in all of the specimens dissected for the extraction of the genitaHa, the abdomen was empty and the tergal sclerites were closely depressed against the sternal ones. Twenty-seven species are listed here; five are new to sci-ence, the others, new to Liberia, belong to species already re-ported from several countries of West Africa. Types and paratypes are deposited in the National Museum of Natural History, Smithsonian Institution collections. Some paratypes are deposited in tlie Institut royal des Sciences na-turelles (Brussels) and in the author's collections. I thank Dr. Paul J. Spangler, Department of Entomology of the National Museum of Natural History, Smithsonian Institu-tion who not only gave me the opportunity to study these Liberian elmids, but was kind enough to revise the English translation of the manuscript.
