 oUes Desvoi y's term later/lia to the buccae (or to the genae) and 

 app ies D^vSc^^^ term medianae to the upper region of the gei.ae. 

 ffibeck (1927) applies the designation intermediate triangle to an 

 "o^espondmg to the latter i^egion (compare also the transverse 

 iSieSon) which corresponds in a general way to the mferior orbit 

 of Loew's terminology. . 



Walton (1909) considers that the '^genae ' ^rf ^onti^^f /^P'lJ^f^f;

 HmMi (1898) applied the designation genovertical plates. Theie is 

 no Ob ectLii to Hough^s term for the areas in question, provided that 

 t is unSood that'the true genae, ge, take no part m the formation 

 oVthriTovertica plates. Lowne (1890) calls these areas the para- 

 ^roi alf ti e pa^^^^^^^^^ of Bezzl 1925), bui they represent only 

 t^e ipp^^^^ of the parafrontal ai^as of lower -^-f^ (--^^ 

 the mrafacials of the Diptera represent the lower areas of the paia- 

 frLS Series of lower insects) and the designation parafrontals
