Piaget’s monogi aphic essay is easily the most valuable treatise on the group, the descriptions being good, the uncolored figures in every way admirable, and the scope of the woik duly monographic. Piaget has fairly attempted to include in his original essay a consideration of every species of Mallophaga described up to 1880. In his Supplement he publishes the descriptions of more than 100 new species which have come under his observation. Taschenberg’s memoir is the first part of what he hopes to make a com- plete monograph of the group. It includes the genera Goniodes, Goniocotes, Lipeurus, Ornithobius, Akidoproc- tus and Trichodectes. The descriptions of new species are very complete, and the keys to species in the consid- ered genera of great value; the illustrations only, though good, are not up to the exceptionally high standard of the work. Taschenberg, like Giebel, has had access to Nitzsch’s types. Of the lesser systematic memoirs Nitzsch’s posthumous papers, edited by Giebel, in the Zeitschrift fur gesammte Naturwissenschaft, vols. xvii, 1861, xviii, 1861, and xxviii, 1866, are the most important; all of their contents are, however, included in the Insecta Epizoa. Next in im- portance, as far as number of described species goes, are Rudow’s papers, consisting of an inaugural dissertation (1869) and several articles in the Zeitschrift fur gesammte Naturwissenschaft, 1869-1870. Rudow’s descriptions are deplorably incomplete; Piaget has practically dis- carded them in his monograph. Of treatises on the Mal- lophaga to be found in text-books of general entomology^ that in Burmeister’s Handbuch der Entomologie, 1S32, is markedly the most complete. Finally, of morphological memoirs, those of Kramer on
