Apparently Koch based his description of transmarinus upon 

 a female while his description of mordax is clearly that of the 

 male. The differences pointed out between the anal legs of 

 these two forms are essentially secondary sexual characters as 

 found in male and female of the present species, although the 

 longitudinal furrows on the mesal surface of the sixth and 

 seventh joints in the female vary in development and may be 

 deeply impressed in some, in others evident upon one or the 

 other of the joints alone, or may be quite absent as seems to 

 be more commonly the case in the males. .Similarly Brolemann 

 (Ann. Ent. Soc. Fr., 1896, pp. 48-41)) in arguing for the dis- 

 tinctness of transmarinus and mordax relies almost wholly 

 upon secondary characters and does not inform us as to whether 

 he is speaking of male or female. He says: "Pour ce qui est 

 des deux especes de Koch, il me semble qu'il ne peut y avoir de 

 confusion, puisque le 4e article des pattes anales des mordax 

 est tres court, tres renfle, parcouru en dessus par un profond 

 et large sillon, ce qui n'est nullement le cas chezle transmarinus." 

 But this is true only of males while the females conform to 

 Brolemann's transmarinus, which must accordingly be regarded 

 as the same species.
