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

 de la Maladie du Sommeil. — I. Pangoniinse." Par le Dr. J. Bequaert.
