Syno'psis of Subfamilies. 



A. Inner lobe of maxillse obsolete or very small; 



gula without luentigerous process ; prothorax 

 marginate at sides ; front coxae strongly 

 transverse Prionince. 



B. Inner lobe of maxillse more or less well 



developed; prothorax not marginate at sides; 

 front 00X36 rarely strong!}^ transverse. 



a. Head more or less elongated and either 



gradually or abruptly narrowed behind 

 eyes ; gula with a mentigerous process, 

 which, as a rule, is very distinct ; mandibles 

 frequently provided with a ligamentous 

 fringe and molar tooth at base ; wing- 

 vein Cu. 1 usually bifurcate behind and 

 joined near middle to Cu. 2. 

 a'. Head very short in front ; antennae 

 close to the base of the mandibles ; 

 front coxae subglobular, with their aceta- 

 bula rounded, or exceptionally slightly 



angulated on outer side Disteniince. 



h'. Head longer in front ; antennae less 

 close to base of the mandibles ; front 

 coxae conical and prominent, with 

 their acetabula more or less strongly 

 angulated on outer side Lepturince. 



b. Head variable in form, but seldom distinctly 



narrowed behind eyes ; gula with or 

 without a mentigerous process, this, Avhen 

 present, usually very short ; mandibles 

 never provided with a ligamentous fringe 

 or molar tooth at base ; wing-venation 

 generally reduced by disappearance either 

 of Cu. 2 or branch of Cu. 1 or of both, 

 sometimes as complete as in Lepturinie, 

 but only in forms which have no distinct 

 mentigerous process to the gula Ceramhycince.

Inner lobe of maxillae obsolete or very small ; ligula corneous ; 

 mentum not covering base of maxillae ; gala without distinct 

 mentigerous process. Antenna? usually inserted close to the base 

 of the mandibles. Prothorax, except in a few species, marginate 

 at the sides. Mesoiiotum, except in the single genus Phllus,
