LXVIII. — Notes on the Synonymy contained in Dr. Bequaerf s recently published Paper on Tabanidie collected in Belgian Congo *. By Ernest E. Austen. (Published by permission of the Trustees of the British Museum.") The paper by Dr. Bequaert forming the subject o£ the present communication contains a number of misapprehen-sions Avhich it seems desirable to correct without delay. The subjoined notes deal solely with species^ and are not concerned with questions relating to genera, otherwise it would not be difficult to show that Dorcaloemus, Austen, which is regarded by Bequaert as a subgenus of Pangonia, Latr , is really entitled to generic rank. Chry sops fusca, Ric, is the c? of C. stigmaticalis, Lw., not of C. distinctipen7iis, Austen, as suggested by Bequaert {t. cit. pp. 2.22-223). The S mentioned by Dr. Bequaert * " Tabanides recueillis au Congo Beige par la Mission pour L'Etude de la Maladie du Sommeil. — I. Pangoniinse." Par le Dr. J. Bequaert.
