. Bulletin of the British Museum (Natural History) Entom Supp. 254 as those of exilis, but the central dorsal process is more developed and is shaped like a wide blade with a scarcely denticulate distal edge ; the lateral processes of the tegumen are thinner and bear at their apices two long rigid bristles ; besides these the posterior edge of the tegumen bears two more short processes, strongly recurved and with apices divided into sharp-pointed teeth ; the valves are pear-shaped ; the penis is of the same shape as that of exilis. I have also examined the male genitalia of B. pseudofea (= isopthalma Herrich Schaffer) and found it to be of the same type as in the two species mentioned above. This uniformity of structure shows the close relationship of these three species, whose venations are identical and whose external appearances are alike. The geographical distribution of the genus Brephidium covers S. Africa (Cape of Good Hope, Natal and Delagoa Bay), the Sonoran region (Florida, Louisiana, New Mexico, Texas and California) and the northern part of the neotropical region (Mexico, West Indies, Central America and Venezuela). It is almost certain that this is a very ancient genus judging by the archaic structure of its male genitalia, the presence of rigid bristles and the beak-like apex of the penis, structures which elsewhere are only found in species of the genus Zizula, a genus also spread over the Old World and S. America. List of Species of Brephidium *Brephidium metophis (Wallengren), i860. Fig. Trimen, 1906. Genus ORAIDIUM Bethune Baker Oraidium Bethune Baker, 1914, Trans, ent. Soc.
